OPPO defends another 5G patent against Nokia's opposition: Mannheim trial scheduled for December, UPC PI motion conceivable, and what would the EUIPO do under the proposed regulation?

Nokia and OPPO are giving each other a hard time in different patent validity fora. Recently, even some Nokia patents that gave rise to German injunctions have been deemed invalid in other--but definitely reputable--jurisdictions. It's a monumental, earth-spanning dispute. There hasn't been anything so large and long-running in the wireless sector for years.

The latest development involves OPPO's EP3624524 on "wireless communication methods, network device, and terminal device." It's a 5G declared-essential patent that OPPO asserted against Nokia in Mannheim, with a trial scheduled for December 5, 2023. In early February, an opposition panel of the European Patent Office (EPO) declared the challenged claims non-novel, but did not take a specific position on (non-)obviousness. Yesterday, the panel upheld the patent in an amended form.

The Bardehle Pagenberg patent attorneys who achieved that partial victory are Tobias Kaufmann and Dr. Nikolaus Buchheim.

In June, another OPPO patent-in-suit was also defended in an amended form, and a modification of the claim language that looked like a minor clarification to me resulted in a non-essentiality determination by the Mannheim Regional Court. So I want to be careful about any predictions at this point. The patent may or may not be standard-essential in its narrowed form. And if it's not essential, then it may or may not be infringed, but an infringement allegation would have to be based on what Nokia's baseband stations actually do as opposed to a (rebuttable) presumption that what reads on the standard is infringed by a product that has been declared standard-compliant. As there is no pretrial discovery in Germany (in fact, nothing even remotely like U.S. discovery), it is far easier to properly plead an infringement case over a SEP than over a non-SEP.

I've recently attended several preliminary injunction hearings before Local Divisions of the Unified Patent Court (UPC): two in Munich (with Bardehle Pagenberg having won one case while the other is under advisement), and one each in Vienna and Helsinki. Companies are increasingly concerned about the implications of a patent surviving, in one form or another, a validity challenge, as the UPC appears rather willing to grant preliminary injunctions over such battle-tested patents, provided (of course) that other requirements, such as urgency, are met.

The Nokia v. OPPO/OPPO v. Nokia dispute showcases various of the things that can happen in SEP enforcement, raising the question of what would happen--or would have happened--if the proposed EU SEP Regulation was already in force.

With respect to what implications the amended claims of EP3624524 would have under the EU SEP Regulation, there are at least two interesting questions:

  • If there had been an essentiality check based on the patent as originally granted, would the EUIPO routinely perform a new one in a situation like this?

  • If the claim amendments pushed the patent out of the area of essentiality, but the patent could still be asserted as a non-SEP, wouldn't the patent holder actually be in a stronger position than if it was deemed essential for purposes of the EU SEP Regulation?

EPO Board of Appeal invalidates standard-essential patent asserted by Nokia in four jurisdictions against OPPO and in at least two against Vivo

The disputes between Nokia and OPPO on the one hand and Nokia and Vivo on the other hand have been going on for some time with no resolution in sight. I noticed that an Indian appeals court ordered OPPO to make some interim payments, but that's not going to force anyone into a global license agreement. Never has, never will.

At the same time, Nokia and OPPO are challenging each other's patents, and I have a few updates about that.

  1. Surprisingly, what appeared to be a minor amendment to the claims of one 5G patent that OPPO is asserting against Nokia was deemed a significant narrowing of the claim scope by the Mannheim Regional Court, resulting in a bench ruling of non-infringement that OPPO may appeal now.

    Thus far, Nokia has managed to defuse all of OPPO's countersuits in Germany, getting some stayed (because of preliminary opinions or decisions concerning the validity of the patents-in-suit) or dismissed. But there still are some cases pending, and as far as I can see, there is no OPPO v. Nokia case yet where all appeals have been exhausted.

  2. Today I learned from the Mannheim Regional Court's spokesman that tomorrow's announcement of what could have been final judgments against OPPO and OnePlus has been canceled. The related proceedings involve EP2087626 on "additional modulation information signaling for high speed downlink packet access" and have been reopened in light of the revocation of that patent by the European Patent Office (EPO).

    It's a dramatic turn of events (or at least it would be dramatic if it wasn't just one of numerous lawsuits in the wider context). OPPO has snatched victory from the jaws of defeat. This is the chronology of events:

    Nokia already asserted EP'626 against Daimler. It was the first of Nokia's patents-in-suit against Daimler to be upheld by the EPO's Opposition Division. The NokiaNews website wrote in 2021 that "Nokia won the first battle in the dispute against Daimler" (though Nokia had previously won a couple of injunctions, this was the first validity decision in Nokia's favor).

    Yesterday, one of the EPO's Boards of Appeal heard OPPO's appeal--and at the end of the appellate hearing declared the patent invalid, just two days before the Mannheim court was going to issue an infringement ruling (presumably an injunction). Theoretically, decisions by a Board of Appeal can be appealed further to the Enlarged Board of Appeal, but only under narrow circumstances, and general guidance from the Enlarged Board of Appeal for future cases wouldn't resurrect EP'626.

    Nokia brought infringement actions over EP'626 against OPPO in Germany, the UK, and the Netherlands, and also sued over member of the same patent family in India and Indonesia (in Indonesia, Nokia's cases were dismissed on procedural grounds; Nokia also brought an Indonesian infringement action against Vivo over a member of that patent family). Nokia also sued Vivo over that patent in Germany.

    Therefore, the invalidation of EP'626 affects quite a number of Nokia enforcement actions. The ones in Germany, the UK, and the Netherlands have been resolved (short of another surprise turn of events). In jurisdictions like India, the EPO decision will serve as persuasive authority.

  3. A couple more Nokia patents have been invalidated in China as the following SIPO documents show:

OPPO effectively defends 5G standard-essential patent against Nokia's opposition: EPO upholds claims based on minor clarification; Mannheim trial scheduled for 6/27

The patent spat between Nokia and OPPO is about two weeks away from its second anniversary. It became known this month that Nokia obtained injunctions against a dozen German resellers of OPPO and OnePlus devices. The parties' efforts to invalidate each others patents (not only the ones that are actually being asserted) are a major part of the earth-spanning dispute. Last month OPPO invalidated another two Nokia patents and a written decision in favor of Nokia's opposition to one OPPO patent came down as well.

This week, OPPO achieved something that might have paved the way for a Mannheim injunction against Nokia this summer. At the end of an opposition hearing held on Tuesday (6/13), the European Patent Office (EPO) upheld, with only a minor clarification added to the claims and the description, one of OPPO's patents-in-suit (click on the image to enlarge):

The patent-in-suit is EP3672346 on an "information transmission method, terminal and network device." The Mannheim Regional Court's Second Civil Chamber (Presiding Judge: Dr. Holger Kircher) will hear the OPPO v. Nokia infringement case over this 5G standard-essential patent the week after next (June 27 to be precise). That trial could get really interesting.

All that it took for OPPO (lead patent attorneys: Bardehle Pagenberg's Tobias Kaufmann and Dr. Patrick Heckeler) to fend off Nokia's opposition was the following insertion into the claim language as well as the first page of the description:

determining, by the terminal, that the time interval is not less than a preset time interval;

An interval defined by a standard is only meaningful if a minimum period of time is predefined. Presumably the relevant determination here is made by the end-user device, so I assume that this insertion is not going to change anything about the essentiality analysis. While OPPO has already exited the German market, I doubt that Nokia would want to do so, and that's why Nokia must defend itself against OPPO's offensive cases or it might have to settle before it gains decisive leverage in another jurisdiction.

OPPO has invalidated another two Nokia patents this month: European Patent Office revoked patents and rejected proposed amendments

The 5G patent dispute between Nokia and OPPO will "celebrate" it second anniversary in about six weeks. Nokia won and started to enforce some German injunctions, but OPPO decided to exit the market--for the time being, and who knows for how long. In other jurisdictions, Nokia did not get leverage either. As a result, the dispute drags on and on, with no resolution in sight.

The parties are attacking each other's patents, not only the patents-in-suit but also additional ones. They've both made some headway, but OPPO's challenges started earlier and that's why OPPO is ahead in terms of actual invalidation decisions (as opposed to preliminary opinions, several of which favor Nokia's attacks on OPPO patents).

OPPO is rather defensive and makes use of its patents only for retaliatory purposes, while patent licensing is a strategic business area for Nokia. Therefore, whatever patents OPPO manages to strike down has implications for what represents a major revenue source to Nokia.

None of the decisions so far is final as they can all be appealed, but this month OPPO has won two more favorable decisions from the Opposition Division of the European Patent Office:

  • On March 3, the EPO revoked, at the end of an oral hearing, EP3167669 on "apparatuses and methods to introduce flexible support for services" in its granted form and also rejected Nokia's proposed amendments to the claims.

  • As the result of an oral hearing on March 9, the EPO also revoked EP3395029 on "methods, apparatuses and computer program product for pdu formatting according to sdu segmentation", in the form in which it was granted and simultaneously rejecting Nokia's proposed amendments (click on the image to enlarge or read the text below the image):

    "The European patent is revoked because, account being taken of the amendments made by the patent proprietor during opposition proceedings, the patent and the invention to which it relates were found not to meet the requirements of the EPC (Art. 101(3)(b) EPC)."

A Chinese article provides an overview of 10 oppositions (nine by OPPO, and a tenth by a third party) to Nokia patents.

There'll be more news from this dispute, unless they settle, which they presumably will, but possibly later, not sooner...

Nokia gets preliminary opinions from European Patent Office according to which two more OPPO patents-in-suit are invalid as granted: outcome will likely hinge on amended claims

It's been more than 19 months since Nokia sued OPPO, and almost as long since OPPO filed its first countersuits. It's already an "epic" dispute. Most other patent spats in this industry are settled within about a year, as a result of which there are normally--at best--some infringement decisions, but nothing significant happens on the post-grant review front before it's already over.

OPPO has managed to get seven Nokia lawsuits stayed over validity doubts, most recently a Munich case. But Nokia is also working hard to poke some holes into OPPO's patent portfolio, and has received preliminary opinions supporting its invalidity theories in several cases.

Late last week, the European Patent Office (EPO) rendered preliminary opinions on two more OPPO patents-in-suit challenged by Nokia:

  • EP3624524 on "wireless communication methods, network device, and terminal device"; and

  • EP3557938 on a "method and device for random access."

As my Nokia-OPPO battlemap shows, EP'524 is being asserted in Mannheim (Second Civil Chamber; Presiding Judge: Dr. Holger Kircher) and EP'938 in Hamburg.

The preliminary opinions reflect that the Opposition Division deems either of those patents invalid in its granted form. But there is still time for auxiliary requests as the related opposition hearings have been scheduled for (different days in) September. Preliminary opinions are "newsworthy", but the longer I watch those EPO post-grant reviews, the more I focus on actual decisions such as this one in January.

No auxiliary requests have been filed for EP'938 so far, and on the ones for EP'524, the EPO did not take a position on the existence of an inventive step:

  • "Claim 1 of Auxiliary Request 1 differs from claim 1 of the patent in that the alternative feature 1.3B has been deleted. Feature 1.3A, which is still present in the claim[,] is not disclosed in D3. For this reason, the subject matter [...] is new [...]."

    The Opposition Division leaves it to the parties to argue for or against the presence of an inventive step, and "note[s] that feature 1.3A is disclosed as such in D1, D2 and D5 [...]."

    A disclosure "as such" is just the starting point of an inventiveness debate. The question is then whether there is a teaching, suggestion, or motivation to combine.

  • "Claim 1 of Auxiliary Request 2 differs from claim 1 of Auxiliary Request 1 in that the features of dependent claims 2 and 3 have been added. So, the 'first time domain unit' has been replaced with the more specific feature 'time slot' and the 'second time domain unit' has been replaced with the more specific feature 'symbol'. So, claim 1 of Auxiliary Request 2 is more restricted than claim 1 of Auxiliary Request 1. Since[] the latter claim is new [...], this also applies [to] claim 1 of Auxiliary Request 2. This applies mutatis mutandis to the other independent claims 5, 8 and 9."

    Here, again, the Opposition Division does not take a position on the inventive step, and "note[s] that 'slot/subframe' and 'symbols' as such are disclosed in D1, D2, D3 and D5 [...]."

  • Auxiliary Request 3 further narrows the scope by specifying that the first research is a search space. Novelty is not an issue, but "a 'search space' as such is disclosed in D1, D2, D3 and D5." This means there will again have to be a discussion of whether there is a teaching, suggestion, or motivation to combine certain prior art references.

The preliminary opinion on EP'524 stresses that Nokia cannot "freely develop as many inventive step attacks as [it] wishes in the hope that one of said attacks has the chance of succeeding." Instead, Nokia will have to present a single theory starting from what it considers to be the closest prior art, unless there are specific reasons for which several starting points are "equally valid."

The Mannheim Regional Court will hold the EP'524 infringement trial on May 23. That court--especially its Second Civil Chamber--is known to be difficult to persuade of invalidity contentions based on an alleged lack of an inventive step. In Mannheim you ideally want to rely on non-novelty as an obviousness theory will not persuade the court to stay the case unless there really is no reasonable argument that can be made for the presence of an inventive step.

Defendants routinely argue in Mannheim and other German courts that an amended claim should not enjoy a strong presumption of validity as it has not been examined. Here, however, OPPO can now point to a preliminary opinion by the EPO's Opposition Division (i.e., by a panel of three patent examiners) that acknowledges novelty and leaves open the question of the inventive step at this procedural juncture. Plus there still is time to file additional auxiliary requests.

There is an asymmetry here: OPPO has left the German market, and there are no signs of it coming back anytime soon. As a result, Nokia's German injunctions do not put OPPO under any particular pressure to settle, but Nokia presumably does want to retain its ability to ship mobile base stations to its German customers. Right now, Nokia has more at stake in Germany than OPPO. If several OPPO patents get invalidated, but one or two are upheld even if in an amended form (so long as they are still infringed), a situation can arise in which Nokia will deem it prudent to settle the global dispute.

Meanwhile, proceedings are ongoing in a Chinese court (Chongqing) to set a global FRAND rate for an OPPO license to Nokia's standard-essential patents.

Should this dispute not be settled in the coming months, then both parties may file complaints with the Unified Patent Court (UPC)...

European Patent Office revoked another Nokia patent last week due to OPPOsition

With the Nokia v. OPPO/OPPO v. Nokia dispute still ongoing, decisions keep coming in. At the beginning of this week, I reported on the Mannheim Regional Court's confirmation of the dismissal of one Nokia v. OPPO complaint, and just before the weekend I've discovered on the website of the European Patent Office that on January 3, the Opposition Division of the EPO--further to an oral hearing held on November 15, 2022--revoked Nokia's EP3298744 on "enhancing data transfer".

All claims were invalidated, and Nokia was not able to salvage the patent in an amended (narrowed) form. Nokia can appeal the decision, though.

It's not the first and probably not the last Nokia patent to come under the revocation wheels as a result of OPPO's opposition filings. In October I reported on preliminary opinions by the USPTO and the EPO according to which another Nokia patent is invalid.

A Chinese website reported in November that OPPO is seeking the invalidation of (at least) 10 Nokia patents. In 9 of those cases, OPPO is the primary challenge, and in a 10th case, OPPO joined proceedings started by other parties (Daimler and its supplier TomTom; Daimler obviously dropped out after a settlement with Nokia). What I have also found now in the EPO Register is a November 23, 2022 notice according to which EP3092836 on a "method and apparatuses for delivering a trigger report for machine type communications". That patent is also listed on ETSI's website. The revocation notice states that the Opposition Division took Nokia's proposed amendments into account, but revoked the patent nonetheless.

No settlement in sight, but more patents to be invalidated or held not to be infringed? We'll see.

OPPO lands several punches as Nokia has to withdraw Mannheim case, USPTO and EPO doubt validity of key patent

Since OPPO's withdrawal from the German market in August, things haven't gone too well for Nokia in its dispute with the Chinese smartphone giant. The exceptions all just confirmed previous wins. For example, Nokia prevailed (on two near-identical patents from the same family) in what is just a tiny market for OPPO: the Netherlands. Also, as the Karlsruhe Higher Regional Court confirmed to me yesterday, it denied OPPO's motions to stay the enforcement of Nokia's Mannheim injunctions (which doesn't mean that OPPO's appeals couldn't succeed; the hurdle is high for such stays in Germany, far higher than in the U.S. where the balance of hardships plays a key role).

In various other regards, those two months have been dreadful for the Finnish wireless company, which is generally managing its patent business very well and has a lot of growth opportunity in that area, but needs an exit strategy from the increasingly costly (not only--but also--in terms of fees) tit-for-tat with OPPO. If things go on like that, Nokia risks finding itself in a Vietnam-style quagmire at a time when some more important renewals are on the horizon.

Nokia had a perfect start: four out of four decisions in Germany (two in Mannheim, two in Munich); or five out of five, but again, two of those patents are barely distinguishable from each other, which is why I count them as one. I could imagine a number of defendants--even more lucrative targets than OPPO--that would have settled at that stage. But OPPO is amazingly resilient. Other patent holders than Nokia will be watching those developments with concern.

After those first four German injunctions, the Dusseldorf Regional Court stayed two Nokia v. OPPO cases, as did the Munich I Regional Court about a month ago.

In a jurisdictional decision, China's Supreme People's Court remained consistent with its OPPO v. Sharp caselaw: according to Chinese media reports, a global FRAND license fee is now going to be determined in China. I haven't been able to find out whether it would be an option for Nokia to leave the Chinese market (should it consider refusing to comply), but it's a huge market for telecoms infrastructure (though Nokia's share may be very low) and a local joint venture (Nokia Shanghai Bell Co., Ltd.), with respect to which Nokia informed its shareholders (PDF) of a financial liability:

"Other financial liabilities mainly include a conditional obligation to China Huaxin as part of the Nokia Shanghai Bell definitive agreements where China Huaxin obtained the right to fully transfer its ownership interest in Nokia Shanghai Bell to Nokia in exchange for a future cash settlement. The financial liability related to the conditional obligation is measured based on the expected future cash settlement with any changes recorded in financial income and expenses in the consolidated income statement. "

A Chinese FRAND determination might provide Nokia with an exit from a war it may never be able to profitably win. Nokia could accept those terms and later tell courts in other jurisdictions that those terms should not be a comparable for the purposes of a FRAND determination in a hypothetical Nokia v. Apple, Nokia v. Samsung or similar case in a jurisdiction like the U.S., UK, or Germany.

OPPO has recently also landed some punches in key Western jurisdictions:

The Mannheim Regional Court yesterday confirmed to me that today's Nokia v. OPPO trial has been canceled. As the court told me, Nokia has withdrawn its Mannheim complaint against OPPO affiliate OnePlus (known for high-end Android devices) over one of the two patents on which Nokia had prevailed in Munich--EP3557917 on a "method and apparatus for providing efficient discontinuous communication." Previously the court (the case was pending before the Second Civil Chamber under Presiding Judge Dr. Holger Kircher) had advised the parties of its preliminary opinion that the patent did not appear to be actually infringed, contrary to what the Munich court had determined against OPPO (as opposed to OnePlus).

Last week, the Patent Trial & Appeal Board (PTAB) of the United States Patent & Trademark Office (USPTO) granted an OPPO petition and instituted an inter partes review of a Nokia patent as OPPO "has shown a reasonable likelihood that it would prevail with respect to all claims challenged in [its petition]" (click on the image to enlarge):

There isn't any infringement litigation in the U.S. between Nokia and OPPO. It's the most transparent jurisdiction, so we would know. This means OPPO itself decided to take the fight to the United States, which is another sign of how determined OPPO is to chase Nokia around the globe.

The PTAB decision follows a preliminary opinion by an opposition panel of the European Patent Office, according to which the European patent from the same family has been deemed invalid (click on the image to enlarge):

In the EPO's preliminary opinion, most of the claims even lack novelty, and claim 4 lacks an inventive step.

While Nokia has a lot of patents and some "weeding out" may be desirable, one question must be asked: is this profitable?

It's not even clear what percentage of its German sales OPPO is actually losing at the moment: Deutsche Telekom (T-Mobile) is still selling three OPPO and two OnePlus devices. And that carrier is a large Nokia customer, so I doubt that Nokia will sue them.

Patent licensing firm IPCom sued Nokia in the 2000s because it was the most lucrative target at that point. The alternative would have been to focus on softer targets. Now it could be that Nokia did everything right except for having underestimated OPPO's ability and determination to defend itself. The ROI of suing some other implementers in the meantime--especially some who are susceptible to German injunctions and for whom it would not be an option to withdraw from the market--would likely have been higher.

Huawei presents itself as unstoppable innovation engine, striving to balance product business and patent licensing interests, expecting more revenue from automotive licensees

Sometimes a coincidence is about as timely as coordination would have been. About a week before Huawei's major IP event that took place earlier today, the German Patent and Trademark Office issued a press release on China having overtaken the U.S. in terms of the number of digital communications patent filings, which is perfectly consistent with European Patent Office statistics. Huawei is the #1 company in that field. While I never described patent counts as the perfect metric (what I'm most interested in is litigation results wherever available), they are yet more meaningful than unempirical opinion papers by economists that incredibly claim to have the definitive answer without evaluating a single patent, much less a statistically representative sample of patents.

Huawei's Chief Legal Officer Dr. Song Liuping (note that this is the Chinese order with the family name before the given name) explained in today's opening address that Huawei increased its R&D investment to 142.7 billion yuan (more than US$21B) last year, amounting to 22.4% of the company's total revenues. Both the absolute amount and the relative share represent 10-year highs. Those numbers are perfectly consistent with the EU Industrial R&D Investment Scoreboard, according to which Huawei has the world's second-largest R&D budget. A significant part of that R&D investment (approximately 15%) relates to foundational research.

Dr. Song noted that Huawei filed more than 10,000 patent applications in each of the last two years (another record high for the company). Huawei filed more than 3,500 patent applications (more than any other company, with Samsung a close second) last year with the European Patent Office alone, and is the number 5 patent filer with the United States Patent & Trademark Office.

You can actually see the number of European patent applications, with only the first digit being hidden (but easy to infer from the other parts of the column chart), behind Huawei's IP Chief Alan fan in the picture the company provided along with its press release on today's event:

Just like so many others with an interest in corporate patent strategies, I've been asking myself in recent years what implications the trade war started by former president Donald Trump and continued by the Biden Administration was going to have for Huawei's IP licensing business. IAM interviewed Mr. Fan a few months ago, and even the headline (pretty much all that one can find in front of the paywall) says Huawei's IP department intended to grow licensing revenues but would not lose sight on the goal of supporting the company's business units. At today's event, Mr. Fan again noted that Huawei, notwithstanding its strong patent portfolio, was still making products (large numbers of them, in fact), so its IP strategy has to be coordinated with the business units.

In the Q&A session toward the end, Dr. Song gave a thoughtful answer to the question of what he regarded as the greatest challenge he faced in his 20+ years at Huawei--an answer that has to do with the hostile environment I just mentioned. Dr. Song said the politicization of business, legal, and technical questions was a major challenge, and one that he undoubtedly deems regrettable as it unnecessarily complicates the quest for solutions that serve the economy at large and society.

What I was primarily trying to figure out today was what Huawei's intentions and priorities relating to its formidable patent portfolio are likely going to be. I got the impression that Huawei's positions are centrist. Neither are they going to be another Apple and pursue the devaluation of standard-essential patents (SEPs) nor are they going to start a suefest. I'm pretty sure we're going to see them resolve most situations through licensing negotiations, but they will likely enforce if it can't be avoided. In the latter case I wouldn't want to find myself on the receiving side.

One industry from which Huawei clearly expects increasing patent licensing revenues is automotive. This much they made clear today. Last year, a SEP license agreement between Huawei and a Volkswagen supplier became known. Huawei is the most significant SEP holder not to license its patents to car makers through the Avanci pool (for now, at least). Huawei has entered into component-level agreements. The fact that the automotive sector was specifically mentioned today suggests to me we'll hear about more bilateral license deals between Huawei and either car makers or their suppliers.

Huawei had some interesting guest speakers with WIPO and EPO backgrounds, a former diplomat who urged cooperation between Western and Eastern countries, one of the elder statesmen of Germany's IP law community (Professor Heinz Goddar, a Boehmert & Boehmert partner), and--quite interestingly--Mattia Fogliacco, the President & CEO of Sisvel, a globally active patent licensing firm and patent pool administrator. Huawei's Alan Fan stated the company's intent to participate in patent pools (as IAM--again, sorry for the paywall-noted in its report on today's event). But there has been no announcement of Huawei's participation in a Sisvel pool unless I missed something. Mr. Fogliacco stressed that a patent pool primarily has two tasks to fulfill: to ensure that the patents in the pool represent true innovation, and to strike a balance between licensors' and licensees' interests particularly with respect to royalty rates.

"Balance" was the keyword here. It's easy to think that a company with a strong patent portfolio, substantial licensing revenues, and an occasional need for enforcement is primarily interested in patent monetization. But the reality is often a lot more nuanced. Despite the impact of the trade war, Huawei is still a major product maker. And even companies like Qualcomm, Ericsson, and Nokia get sued by patent holders more often than one might think (either directly or in the form of patent assertions against their customers). Case in point, an IP Watchdog article just criticized a U.S. court ruling in a case where Qualcomm had to defend itself.

Huawei is a licensor as well as a licensee, a SEP holder as well as an implementer of standards, and that was unmistakably reflected by the content, topics, messages, and the speakers at today's hybrid (in-person plus online) event. There wasn't a particular announcement oaf a license deal or partnership. Instead, the part I personally liked best was when three very young inventors--almost fresh out of university--presented the innovations they created at Huawei, such as (now quoting Huawei's press release) "an adder neural network that significantly reduces power consumption and circuit area to a game-changing 'optical iris' that provides a unique identifier for optical fibers." Now I'm waiting for announcements relating to license deals and the participation in patent pools--and enforcement action though they appear to try hard to avoid those in the first place.

European and German patent stats confirm China has taken lead over U.S. in digital communications patent filings: Huawei, Ericsson lead the pack; OPPO ahead of Nokia; Apple is nowhere

Yesterday, the German Patent & Trademark Office (Deutsches Patent- und Markenamt; DPMA) issued a press release on its 2021 annual report, and the headline translates as follows:

"China ever more innovative in digital technologies"

The German PTO highlighted that China has, for the first time, overtaken the United States in the field of digital communications technology patent applications as its numbers increased by 6.8% from 4,032 to 4,308, while the figure for the United States--home to the most aggressive proponents of the devaluation of standard-essential patents (SEPs)--went down by 2.4% from 4,218 to 4,115. Even if the U.S. figure had remained stable, China would have taken the lead.

While China's ascent to the top is indisputably impressive, it's arguably no less remarkable that Sweden--a relatively small country --is #4 on the list as it overtook Korea. Sweden's patent filings in this field went up by 3.6% (from 1,223 to 1,267--more than quarter of China's numbers!), while Korean patent applications declined by 5.8% from 1,249 to 1,176.

If we want to understand these dynamics, which are immensely important from an innovation policy perspective as well as with respect to pending SEP litigations (Ericsson v. Apple (Apple is countersuing only over non-SEPs), Nokia v. OPPO/OPPO v. Nokia), we need to take a look at the major players. The German PTO's annual report doesn't list particular filers, but fortunately the European Patent Office (EPO)--whose report equally attests to China's and Sweden's incredible achievements--provides a list of the top 10 filers in the field of digital communications (click on the image to enlarge):

Key takeaways and observations

  • Despite Trump's trade war that the Biden Administration continues, Huawei is unstoppable--and the undisputed number one in the world. They have a corporate presentation coming up next week, and I plan to follow it over the livestream--it's a must-attend given that company's strength in wireless patents.

  • The other Chinese companies among the top 10 filers in the field are OPPO (#5), which is in the top 5 and has surpassed Nokia (688 v. 658), with which it is embroiled in two-way litigation; ZTE (#7), which is increasingly interested in outbound licensing and has recently started enforcement actions and Vivo (#10), which is being sued by Nokia but also countersuing in Dusseldorf.

  • Ericsson is #2, clearly ahead of Qualcomm in the third place and more than twice as strong as Nokia (#6). Sweden's strength in digital innovation is almost entirely attributable to Ericsson alone. One cannot respect innovation without applauding Ericsson's engineers.

  • But what about Apple, against which Ericsson is enforcing SEPs? Nowhere on the list. Over the years they've acquired SEPs (such as from Nortel and Intel), but that's about it. It's been a few years since they acquired Intel's mobile chipset business, so I'd have expected them to play a more significant role already. But... they are nowhere to be seen.

    Apple is a luxury goods company making the closest thing you can find in the digital economy to a Veblen good. More than anything else, Apple brutally exploits its market power over everyone, with my primary concern being how it treats app developers. It squeezes suppliers and seeks to deprive employees of their rights to form unions (just yesterday, Microsoft announced a far more cooperative stance on unions).

    Policy makers in the U.S. and elsewhere must understand where Apple is coming from when it takes positions on patent policy and on mobile app stores. It seeks to substitute market power for foundational research. That formula, however, doesn't yield a consumer surplus. Nor are deceptive lobbying practices by Apple-funded organizations the answer.

    Apple won't change unless it has to. It's up to policy makers, competition regulators, and the courts of law to require Apple to compete on the merits, to fairly reward innovators, to open up iOS app distribution, and to invest not only in its expansion into ever more markets (it's like an insatiable octopus in that regard) but also in the digital communications technologies without which its gadgets wouldn't work in the first place.

    The United States has no one but itself--and above all, Apple's ability to perpetuate its market power and spawn monopoly after monopoly--to blame for having lost the lead in this field to China, and for trailing (relative to population size) a country like Sweden by a huge factor.

New § 83 of German Patent Act entered into force today, requiring Federal Patent Court to hand down preliminary opinions within six months: foolish and pointless 'reform'

The most stupid piece of patent legislation I've ever seen--apart from bills that never got enacted--is PatMoG2, last year's German patent "reform." Most of it entered into force in mid-August 2021, and 8 1/2 months later there still hasn't been a single case in which the "proportionality" language inserted into § 139 made a difference. What those advocating for stronger defendants' rights pursued as their #2 priority was a plan to mitigate the effects of bifurcation (invaliditation proceedings typically taking much longer than infringement cases). In that regard, too, the only clever and honest way to deal with it would have been for those "reform" advocates to tell politicians--politely, but clearly--"thanks, but no thanks." Instead, they contented themselves with crap, hoping that it would enable them to falsely claim victory without changing a thing in practice.

It was a win-win-win situation in the sense that patent holders preserved the status quo, "reform" advocates had something to show (though anybody who knows how patent litigation in Germany works wouldn't expect different outcomes), and politicians could make it look like they had solved a problem.

Short of abolishing bifurcation (as Judge Pichlmaier suggested in his comments to Juve Patent), the only thing that would have helped net licensees is a lower hurdle for getting cases--or the enforcement of injunctions--stayed. Oddly, a lower standard for staying the enforcement of injunctions during an appeal was even proposed as a solution by certain lobbyists representing key net licensors. But the misguided and incompetent "reform" camp didn't take the deal, and got nothing useful in the end.

All they achieved was that the German legislature inserted language into § 83 PatG (Patentgesetz = [German] Patent Act) that calls on the Bundespatentgericht (Federal Patent Court) to hand down its preliminary opinions on nullity complaints within six months of service of a given commplaint on the patent holder. That new § 83 PatG entered into force only today as a grace period was needed so the Federal Patent Court could adjust. Today is a Sunday (plus, a national holiday (Labor Day)), but if you are patent holder and a nullity complaint is served on you anytime now, then the six-month target applies.

Yes, it's merely a target, not a rule. You can't get an infringement case stayed only because the Federal Patent Court takes longer. And six months is typically quick enough for main proceedings, but doesn't solve any problem in fast-track preliminary-injunction proceedings.

If a patent is less than nine months old, it can still be challenged before the patent office (usually the European Patent Office). In that case, one cannot file a nullity suit yet. It is an oversight--due to incompetence by too many of the people involved--that the "reform" bill doesn't address this problem. The Federal Ministry of Justice realized this when it was too late, so the measure got enacted anyway, but there is a plan to publish a "bugfix" at some point.

Even in those cases in which the six-month target applies, what good it will do? I'm very, very skeptical.

I actually have a lot of sympathy for the judges over at the Federal Patent Court. Those "reform" advocates complained about how long it takes until those nullity complaints get adjudicated, but that's because of the court's caseload. Granted, the Federal Patent Court could decide more cases if it reduced the number of judges on a nullity panel from 5 to 3 and/or didn't require every single judge to write an opinion for internal purposes only the per curiam gets published in the end). But that's not the judges' fault either.

Defendants to infringement lawsuits must present their nullity action at the time of responding to the infringement complaint (in order for the infringement court to consider it). From service of the nullity complaint, patent holders have two months to respond in defense of their patents. That period was often extended, sometimes up to five months, and now the Federal Patent Court is going to be extremely reluctant to grant extensions. That will also apply to the reply briefs that nullity plaintiffs submit.

The Federal Patent Court will, therefore, have a pretty developed record in front of it early on. But will it then actually render preliminary opinions that are going to help the infringement courts as they have to decide on whether to stay a case pending a parallel nullity action?

Even the six-month target isn't legally binding, but time is at least measurable. What simply cannot be measured is the quality of what the Federal Patent Court will deliver at that early stage.

That court won't all of a sudden have far more judges. It can't do magic just because of that new § 83 PatG setting an insanely ambitious target. With the old timeline, about half of all cases never reached the point at which the judges even had to seriously assess the merits: disputes often got settled before. Now the court has to form an opinion--albeit only a preliminary one--on virtually 100% of all cases, and on a very short timeline.

The predictable net effect is that the Federal Patent Court's preliminary opinions will simply be less helpful than in the past (where they came down at a much later stage). There is no hard and fast requirement that those preliminary opinions must actually indicate in which party's favor the court is inclined to rule. In fact, the very § 83 PatG merely says that the court shall inform the parties at the earliest stage possible of "aspects that will foreseeably be particularly relevant to the decision or serve to focus the oral hearing on the outcome-determinative questions." In other words, those preliminary opinions don't have to be opinions. Acctually, they aren't even called preliminary opinions in German: the more literal translation of "Hinweis" is closer to "notice."

All that the Federal Patent Court has to do in order to reach the (non-binding) six-month target is to lay out the agenda. It doesn't have to decide on claim construction at that stage, nor does it have to express an opinion as to whether the challenged patent was anticipated by a given prior art reference or doesn't involve an inventive step over a combination of prior art references. The court can just identify what questions are in dispute between the parties. That's it.

Those advocating "reform" wanted fast food, and fast food--not gourmet food--they shall get.

Is that going to assist the infringement courts (which are in a position to identify the bones of contention by themselves)?

Is that going to result in more stays of infringement proceedings?

Are the judges of the Federal Patent Court going to be forever grateful to the automotive industry and Big Tech for having called into question their efficiency and for having lobbied for something that just puts unreasonable pressure on them?

No, no, and no.

Nokia 4G patent upheld by European Patent Office, stronger than ever thanks to Daimler's wasteful litigation effort

The dispute with Daimler is the gift that keeps on giving to Nokia. The case settled seven months ago, but yesterday Nokia's EP2550762 on "signalling of channel information" got upheld by an opposition panel of the European Patent Office with only a minor amendment, which still allows Nokia to claim that it is essential to the 4G/LTE standard. The patent relates to carrier aggregation (aggregating bandwidth from different parts of the spectrum).

Nokia didn't assert that standard-essential patent (SEP) against Daimler, but it was on a list accompanying Nokia's infringement notice, so Daimler and its supplier TomTom challenged it, possibly also hoping to drive up Nokia's litigation costs. Daimler wasn't actually listed as a party, but their lawyers (Quinn Emanuel) obviously weren't opposing the patent pro bono.

Let me quote from the EPO's summary and a pagraph that will now be inserted into the patent specification:

"In independent claims 1, 4, 7, 11 and 14 of the present patent, a disclaimer has been included for differentiation from this prior art document"

This makes the patent more valuable for Nokia's future 4G enforcement campaign. It is a significant accomplishment for Nokia's patent attorneys, Cohausz & Florack partners Bjoern Brouwers and Dr. Christoph Walke. It wasn't easy because the opposition board raised some issues in a preliminary opinion. The opposing parties, however, withdrew well in advance of yesterday's oral hearing.

Some automotive companies have yet to learn how to get their money's worth in patent litigation. Sometimes the economically smarted choice is to take a license. Before Daimler reached that conclusion and took an Avanci pool license, it had already paid substantial "tuition fees" in the form of ultimately unsuccessfully defending itself against Nokia, Sharp, and Conversant--and an IP Bridge case against Daimler would have gone to trial in Munich later this month.

Earlier today I also questioned the wisdom of Ford defending itself against Avanci licensors Sisvel, IP Bridge, and Longhorn IP.

When Daimler settled with Nokia, the Finnish wireless company had won "only" one injunction each in Mannheim and Munich. But shortly after that settlement I looked more closely at the state of affairs in various proceedings, only to find that Nokia would probably have been able to enforce the Mannheim injunction without a need to provide security in possibly just a matter of months, and that Nokia would very likely have won several more injunctions. That is not to say that no one can defend against Nokia: sophisticated smartphone companies would do a better job than Daimler. An interesting benchmark: OPPO outperformed Daimler against Sharp.

Daimler's litigation department managed that litigation a bit like people who order whatever item on the restaurant menu is priciest. You could take a burger straight out of McDonald's, put it on the menu, charge $350, and those types of people would order it even if they could get a filet mignon from wagyu beef at half the price at what would still be an upscale restaurant on the other side of the street. There came a point when others in the organization were no longer prepared to support that wasteful spending. Now they just have to realize at Daimler that it's a mistake in German patent litigation not to hire interdisciplinary teams consisting of attorneys at law and patent attorneys. Patent attorneys won this one for Nokia.

Nokia definitely got a lot of value out of the Daimler dispute. But again, sophisticated tech companies, above all smartphone makers, are the real challenge, provided that can come up with a new challenge to EP'762 as merely rehashing Daimler's unavailing arguments won't help.

First four OPPO v. Nokia countersuits over 5G patents have been docketed in Mannheim, Munich, and Hamburg

About a month ago, Gizmochina reported on OPPO having filed countersuits over 5G patents against Nokia in China and an unspecified number of European jurisdictions. This is what I expected to happen, especially after I became aware of the litigation prowess the Chinese smartphone maker demonstrated in its recently-settled dispute with Sharp. OPPO is to be reckoned with, and as OPPOsed to letting others push it around, it fights back. I don't know whether OPPO brought any patent infringement counteractions against Sharp, but I have been able to find out about a couple of Dutch declaratory judgment proceedings, such as one targeting Sharp's EP'181.

Now, against Nokia, OPPO is also claiming that its own 5G patents are infringed. While I haven't yet been able to find out enough about the cases in China and other European jurisdictions that I could meaningfully write about them, OPPO's first four offensive cases in Germany have been docketed--by three different courts:

  • Mannheim Regional Court:

    • Case no. 2 O 112/21 (Presiding Judge Dr. Holger Kircher) over EP3624524 on "wireless communication methods, network device, and terminal device"

    • Case no. 7 O 125/21 (Presiding Judge Dr. Peter Tochtermann) over EP3547772 on "data transmission method and apparatus"

  • Munich I Regional Court:

    • Case no. 7 O 11301/231 (Presiding Judge Dr. Matthias Zigann) over EP3563600 on "separate configuration of numerology-associated resources"

  • Hamburg Regional Court:

    • Case no. 315 O 217/21 over EP3557938 on a "method and device for random access"

Three aspects of these first four discoverable OPPO v. Nokia cases stand out, the first two of which relate to venue selection:

  1. Wireless patent cases are very rarely filed in Hamburg. That's why this blog has so far not reported on a single Hamburg patent case other than mentioning an Avago (Broadcom) case against BMW two years ago. In that case, the law firm of Bardehle Pagenberg was on the defending side. Bardehle is one of two law firms representing OPPO against Nokia in Germany. The other is Hogan Lovells.

    For lack of local case law, the Hamburg Regional Court is a dark horse with respect to standard-essential patent (SEP) enforcement--and a case like this is an opportunity for that court to make a decision that might get a lot of attention and attract more filings of that kind.

  2. Both Hogan Lovells and Bardehle have offices in Dusseldorf, and Nokia brought some of its own cases against OPPO in that city. In Mannheim (the center of gravity of that dispute) and Munich, suits are flying bidirectionally. In Dusseldorf, OPPO doesn't appear to have responded to Nokia's cases yet (maybe because it's a much slower court than Munich and Mannheim), and instead elected to go north and open another battle front in Hamburg.

  3. The patent numbers immediately struck me as high: OPPO's patents-in-suit are very young. The window for filing an opposition with the European Patent Office is still wide open.

    This has an interesting procedural effect: even if Nokia makes its opposition filings pretty soon (which I guess it will), the EPO is not going to start the opposition proceedings until the opposition period has expired. That's because it would be inefficient for the EPO to commence the process while there is a possibility of further filings being made with respect to the same patent. As a result, OPPO's infringement cases are almost certainly going to be adjudicated before the EPO's opposition division renders any preliminary validity assessments.

    By the way, the six-month target (merely wishful thinking by lawmakers, not a hard and fast rule) under this year's German patent reform for the Federal Patent Court to hand down a preliminary opinion wouldn't apply anyway (too early for that)--and due to a gaffe by the lawmakers and governmental officials involved with the drafting of that reform bill, patents young enough to be opposed before the EPO wouldn't have been affected anyway. It's a blunder--it's what happens when those make patent law don't really understand how things work in practice. The ministry officials told stakeholders they hoped the incoming government (most likely a new government coalition in light of the outcome of recent elections and early-stage negotiations between the parties) would take an initiative to amend the law during this new legislative term. But that's another story, as these cases were filed too early to be affected by the reform even if Nokia had been able to challenge those patents in the Federal Patent Court.

Nokia tends to double down once someone countersues. Escalation is presumably inevitable in this dispute. There is a lot at stake given the huge unit volume that OPPO and its affiliates (Realme, OnePlus etc.) represent, and at a point at which Nokia has some major renewals coming up (Samsung--with whom they appear to have resolved only peripheral licensing questions, but haven't tackled the real issue (5G) yet--as well as Apple). At the same time, OPPO can't afford to appear to be a soft target: otherwise it will face a neverending barrage of patent assertions by patent holders of all sizes, not just the Nokias of the world but also numerous non-practicing entities.

From a cross-licensing point of view, Nokia's advantage is minimal expose. Nokia's own unit volumes are low because there's a huge number of handsets sold in the world per each base station, and Nokia is only in the latter business now. Today's Nokia phones are made by a third party named HMD, which has a trademark license but is otherwise independent from Nokia. OPPO can therefore sue only over Nokia's base stations.

An escalating multi-jurisdictional SEP dispute between one of Europe's two most important wireless companies on the one hand and a high-volume rising-star Chinese electronics company on the other, while the other European wireless giant--Ericsson--is apparently meeting resistance by Apple to a royalty demand that is tiny compared to Apple's sales and margins, is definitely not the context in which the European Union would be prepared to reduce SEP holders' leverage by weakening enforcement. Europe's automotive industry and other net licensees won't get their way. At the end of the day, policy makers can see clearly that the automotive industry is in a position to resolve its SEP licensing woes at a manageable cost, but car makers largely even refuse to take Avanci's $15/unit pool license. Whether the European economy as a whole is a net licensor or net licensee of SEPs doesn't matter: the thing is that European net licensors very much need to generate revenues from licensing, while for car makers it's just a minor cost of doing business, no matter how much they may be crying--and whatever European car makers end up paying will also have to be coughed up by their competitors on the world stage. Therefore, industrial policy considerations are going to dissuade the European Commission from tampering with SEP enforcement at this juncture.

I'll keep researching and monitoring the Nokia-OPPO dispute, and hope to be able to provide more litigation data in the not too distant future.

Apple and Intel just dealt Qualcomm a post-settlement blow: EPO revokes patent underlying German fake injunction against iPhone 7 and 8

On the legal front, this week was the worst ever for Qualcomm in its corporate history, due to the FTC's sweeping victory in the Northern District of California on Tuesday shortly before midnight Pacific Time. Today, Friday, Qualcomm suffered another defeat--less impactful than the other one, yet significant: a three-examiner panel of the Ppposition Division of the European Patent Office (EPO) sided with Apple and Intel by revoking, as requested by those two Silicon Valley companies, European Patent EP2724461 on a low-voltage power-efficient envelope tracker, a patent that Qualcomm temporarily enforced to prevent Apple from selling the iPhone 7 and iPhone 8 (and the iPhone X, but Apple was no longer offering it anyway) in Germany, an attempt to put pressure on Apple for which Qualcomm had to make a $1.5 billion deposit.

Quite apparently, the recent Apple-Qualcomm settlement agreement, which resulted in the dismissal with prejudice of all infringement and antitrust/contract actions around the globe, did not and does not preclude Apple from continuing to challenge the validity of Qualcomm's EP'461 patent, which I just call the "Munich fake injunction patent" alluding to its enforcement history. (This is not the time and place to speculate on whether that agreement will have to be renegotiated; suffice it to say that a hedge fund manager with formal legal training said, as a guest speaker on a Susquehanna International Group conference call yesterday, that he couldn't find anything in the redacted version of the agreement that would suggest it couldn't possibly happen, and he explained why it's actually even hard to imagine that even the most creatively-crafted clause in the agreement could deprive Apple of whatever rights it might have as a beneficiary of the FTC case.)

On Tuesday, I was first to report and comment on Judge Lucy H. Koh's antitrust ruling; today I was the only third-party person in meeting room 128 of the EPO's main building in Munich. Qualcomm had dispatched a team of eight: four Quinn Emanuel lawyers (led by two partners: lead counsel Dr. Marcus Grosch and recently-named partner Jérôme Kommer), a German professor who served as their expert witness, and three Qualcomm employees from San Diego. Apple and Intel were represented by four patent attorneys from Samson & Partner (including the name partner himself, Dr. Wolfgang Lippich, Dr. Georg Jacoby, and Dr. Martin Vetter) as well as--in an advisory, non-pleading capacity today--Freshfields Bruckhaus Deringer partner Prince Wolrad of Waldeck and Pyrmont and principal associate Dr. Eva-Maria Herring, credited for numerous key court filings such as Apple's answers to several Qualcomm complaints.

Such a rock-star lineup on both sides--14 professionals in total--shows that today's hearing was hugely more important than one might have thought in light of the recent Apple-Qualcomm settlement as well as the Munich Higher Regional Court's decision to lift, pending the appeal (which was subsequently mooted by the settlement), the lower court's injunction because it came down for all the wrong reasons.

The relevance of today's ruling by the EPO's Opposition Division, which Qualcomm can and undoubtedly will appeal to a Technical Board of Appeal (TBA) of the EPO, transcends the scope of, and past and potential future harm caused by, this particular patent as the German federal government is preparing a patent reform package with a particular emphasis on access to injunctive relief. In fact, an "expert talk" (a spokeswoman for the ministry insisted it was not a "roundtable," though I think it was one by any other name) took place just earlier this week--and I'll encourage the officials in charge of drafting the bill to consider this case, which was arguably the highest-profile German patent injunction that ever came down. I'll also remind them of how German media giant Bertelsmann's Arvato services company lost a great deal of business from Microsoft earlier this decade because of the mere threat of a Mannheim injunction>.

Let's look at it this way: because of German patent law--and the way the courts apply it--effectively granting patent injunctions as an automatic conseqwuence of an infringement finding, and because defendants are deprived of a full invalidity defense (unlike in any other jurisdiction, though it's also a tall order to get U.S. juries to invalidate patents), two models of the commercially most successful high-tech product ever--the iPhone--were banned by the Munich I Regional Court even though

  • the appeals court found that the lower court erred in three ways, one of which is that the regional court should have reopened the record after the first trial instead of entering an injunction,

  • decisions in the U.S. (by the ITC and the United States District Court for the Southern District of California) very strongly suggested that Qorvo's envelope tracker chip simply doesn't infringe that patent, and

  • today we know that the patent shouldn't have been granted in the first place (though, again, Qualcomm can and presumably will appeal that holding).

It was a long day (from 9 AM to around 5 PM local time) at the EPO, and I'd rather go into details on the invalidity finding when the written decision is handed down. What I do wish to point out is that the opposition panel (chairman: Manuel Pavón Mayo; 1st examiner: Ali Hijazi; 2nd examiner: Thomas Agerbaek) chose a very well-structured and logical approach today that I really liked. They adopted Dr. Lippich's suggestion to start with claim construction (especially the pivotal term, "offset") so as not to put the cart before the horse (in the U.S., that's just normal; in Europe, it unfortunately isn't, but I hope it will be at some point); just before the lunch break, they determined that the patent was invalid as granted; thereafter, Qualcomm (whose lead counsel is generally very successful with claim amendments as I've seen on other occasions) brought what they call an "auxiliary request," which is an amended claim; Apple and Intel's first attack on the validity of the amended (narrowed) claim failed, but the second one, based on a different closest prior art reference, succeeded after extremely thorough analysis with a lot of back and forth and several breaks that were required to arrive at this well-considered decision (which I therefore believe stands an excellent chance of affirmance).

I also wish to thank the EPO's press office for their support, despite the fact that there were times when I was an enemy of the EPOnia state, though I have for several years now refrained from commenting on their internal matters. Today a highly competent and dedicated panel did some world-class work.

Finally, I'd like to get back to Judge Koh's ruling. On page 104, she also addressed this problem of Qualcomm using non-standard-essential patents such as EP'461 against Intel-powered Apple devices in order to bring Apple back into the Qualcomm fold:

"Once Apple started purchasing modem chips from Intel, Apple challenged Qualcomm’s royalty rates, as Tony Blevins (Apple Vice President of Procurement) testified at trial: 'There are court proceedings where we’re trying to establish what is a FRAND rate for royalty.' [...] In response, according to Blevins, Qualcomm sought patent injunctions around the world against Apple’s handsets: '[T]hey had filed injunctions against Apple and lawsuits on non-SEPs, again, to improve their position . . . on the SEPs.' [...]"

I remember, from watching the San Jose trial in January, how counsel for Qualcomm tried to get an FTC witness to say that Qualcomm's royalty demands would be validated by Qualcomm being able to shut Apple out of a major market like Germany. So much for that one.

Munich I Regional Court schedules additional June trial over Qualcomm's four zombie patent lawsuits against Apple

Four of Qualcomm's eight Spotlight-related patent infringement actions against Apple in Munich were dismissed in January for non-infringement, while the proceedings relating to the other four cases (two lawsuits per patent targeting different Apple entities) were reopened because Qualcomm had not yet had the opportunity to argue that a panel of three examiners at the EPO's Opposition Division erred when they preliminarily agreed with Apple and Intel that those patents are invalid.

I checked again with the press office of the Landgericht München 1 (Munich I Regional Court) and was told yesterday that "for the time being" the court scheduled another trial session for June 13, 2019. The parties already argued (non-)infringement at a first hearing as well as a trial last year, so presumably the sole focus of the additional June session will be on (in)validity.

Five and a half month later, on November 26, 2019, the EPO's opposition panel will hold a hearing and make its decision (click on the image to enlarge; this post continues below the image):

In German infringement proceedings, defendants' ability to argue invalidity is limited. As opposed to a full invalidity defense, there is bifurcation: full invalidity challenges must be brought in separate fora (the EPO for "young" patents, or the Federal Patent Court of Germany), and the courts deciding on infringement will, at best, stay a case pending the resolution of a parallel invalidation proceeding. The decision on a request for a stay is based on limited analysis as opposed to a full trial. In practical terms, obviousness arguments are hard to prevail on; stays are usually based on indications of non-novelty.

However, when a competent forum deems a patent invalid, its findings bear significant weight with the infringement court. A credible invalidity opinion from a forum within the European Patent Organization (the international organization running the EPO) often has the practical effect of reversing the burden of proof, requiring the patent holder to persuade the court that the related findings are either not well-reasoned or, should a patent not be young enough that the EPO can revoke it Europe-wide, are based on a legal standard that German courts don't apply to the German parts of EPO patents.

Here, the EPO's opposition panel took a preliminary position, with the actual hearing taking place later this year. A preliminary holding like this obviously has significantly less weight than a final (but appealable) revocation decision. But it was important enough to warrant a reopening of proceedings.

Qualcomm isn't going to gain any leverage from those Spotlight (a search feature) cases anyway as iOS 12 contains a workaround. Any "win" would be purely symbolical, as would any potential damages. But Qualcomm is facing huge problems in its patent infringement actions against Apple, which is presumably the reason why it keeps spending a lot of money on cases that won't result in any serious leverage. Qualcomm is desparately trying to prove that its patents (in these cases, non-standard-essential patents) have value, and to portray Apple as an infringer--even when there's already a workaround in place.

Maybe Qualcomm will stipulate to a stay so the Munich court won't have to hold the mid-June trial session and write up an order to stay the case. Given that the EPO will decide only five and a half months later, it's hard to imagine (though I have no idea of what Qualcomm told the court as to why it believes the EPO got it wrong) that Qualcomm will be able to dissuade the court from staying the cases. It's also very, very likely that the EPO will revoke those patents, in which case Qualcomm will have to appeal the Opposition Division's decision to a Technical Board of Appeal. All of his is taking time, but those cases are pretty clearly going nowhere.

Later this month a first hearing in a later-filed Munich Qualcomm v. Apple case over an antenna patent will be held.

BlackBerry suing Facebook and its WhatsApp and Instagram subsidiaries over five European software patents in Munich

As the former director of the European NoSoftwarePatents campaign I always find it shocking what kinds of patents the European Patent Office (EPO) grants despite the exclusion of "programs for computers as such" from the scope of patentable inventions according to Article 52 of the European Patent Convention (EPC).

Post-grant reviews often do away with those patents, but rarely ever on the basis of Art. 52 EPC per se. What typically happens is that the Federal Patent Court of Germany or other courts of competent jurisdiction categorize some claim limitations as "non-technical" and purposely ignore them in their novelty or inventiveness analysis. Whatever little remains then is often anticipated by, or at the very least obvious over, the prior art. But, unfortunately, efficiency gains (reduced data volumes, increased processing speeds, economic use of screen space etc.) often serve as an excuse for circumventing Art. 52 EPC.

Tomorrow the Munich I Regional Court will hold a first hearing in one of eight BlackBerry v. Facebook/WhatsApp/Instagram cases over a total of five different patents--all of them pure software patents. Patents on "programs for computers as such."

In March 2018, BlackBerry sued Facebook as well as its WhatsApp and Instagram subsidiaries in the Central District of California (= L.A., though geographically it would be SoCal). Facebook's VP of Litigation and Deputy General Counsel, Paul Grewal, issued the following statement:

"Blackberry’s suit sadly reflects the current state of its messaging business. Having abandoned its efforts to innovate, Blackberry is now looking to tax the innovation of others. We intend to fight."

The fact that Facebook still isn't paying BlackBerry any royalties is a good sign. Don't feed the failed-business-turned-troll!

Mr. Grewal used to serve as a United States Magistrate Judge in the Northern District of California. Over the years this blog mentioned him quite often, most notably in connection with Apple v. Samsung discovery and (un)sealing disputes as well as his mediation effort with Oracle and Google, a case that he realized just had to go to trial.

While there has been some media coverage of BlackBerry's U.S. litigation against Facebook (and a countersuit by Facebook), I haven't been able to google any articles on the eight Munich lawsuits, even though a couple of first hearings have already taken place there. This is the list of patents and first hearing dates:

  1. EP1734728 on a "method and apparatus for switching between concurrent messaging sessions" (first hearing held on 01/10/2019)

    accused functionality: showing two chat histories in parallel

  2. EP1633114 on a "system and method for maintaining on a handheld electronic device information that is substantially current and is readily available to a user" (first hearing held on 01/17/2019)

    accused functionality: automatically identifying user profiles containing partly identical data

  3. EP1746790 on a "method of sharing an Instant Messaging history" (first hearing: tomorrow = 02/14/2019)

    accused functionality: sharing messages from the chat history

  4. EP1540495 on a "method and system for displaying group chat sessions on wireless mobile terminals" (first hearing: 02/28/2019)

    accused functionality: displaying chat history while text is being edited

  5. EP2339799 on an "IM contact list entry as a game in progress designate" (first hearing: 02/28/2019)

    accused functionality: chatting during gameplay

This is another series of Munich cases in which Quinn Emanuel is asserting patents on behalf of a patent monetization-focused client against a Freshfields client. QE is representing Qualcomm against Apple in a series of German infringement cases, and Freshfields is defending Apple. Here, QE is suing Freshfields client Facebook on BlackBerry's behalf.

The BlackBerry company was named Research In Motion (RIM) when it filed the related patent applications. The irony is that "Research In Motion" is structurally similar to the names of many patent trolls, but the company was actually focused on making products at the time and itself the target of lawsuits brought by trolls, with the NTP case (settled for $612.5 million) being the most well-known example, while it's now named BlackBerry, but far more interested in patent monetization while its namesake products became pretty irrelevant a long time ago, thanks to the iPhone and Android.

I was in frequent contact with RIM in 2006, shortly after the costly NTP settlement that happened on the eve of what would most likely have been a U.S. injunction. I remember that they were the first company (of many) to tell me about the problems they had with Qualcomm, and that they were really happy about the Supreme Court's eBay v. MercExchange ruling (on patent injunctions) that year. But times have changed, and now they're asserting software patents against Facebook and its two most famous subsidiaries as if Article 52 of the European Patent Convention didn't exist.

In addition to suing companies like Facebook directly, BlackBerry engages in privateering. Last week, PatentlyApple reported on a declaratory judgment action brought by Apple against a troll named "Fundamental Innovation Systems" that wants (but hopefully won't get any) license fees from Apple over a dozen former RIM/BlackBerry patents.
