Apple v. Samsung Saga

The long-running patent battle between Apple and Samsung took a comedic turn when the CAFC (2015-1171) threw out a $120 million judgment against Samsung for infringing Apple touch-screen patents that were obvious (8,046,721 & 8,074,172). Through bogus claim construction, the district court was also reversed in finding Samsung infringing Apple's 5,946,647 patent, which claimed an "analyzer server" that Samsung did not employ in its similar technology. The upshot: pathetic jurist work by Northern California Judge Lucy H. Koh.

Not Running

Commil USA v Cisco (CAFC 2012-1042) illustrates the incompetence of the patent law system in the US. The case went up to the Supreme Court and back down to the CAFC before being settled on a rather simple, well-established technical fact of non-infringement: Cisco did not run a claimed protocol at each mobile device. Instead, Cisco used a single copy of the protocol for all connected devices. This overturned a jury verdict which the district court judge had let stand. The CAFC panel noted that "a reasonable jury" could not have found what it did. Which is to say the reasonable juries do not exist. Not to mention district court judges on up.

Fenner Investments sued Verizon Wireless for infringing 5,561,706, which claimed locating and tracking "personal identification numbers." Claim construction of "personal identification numbers" as being personal led to stipulation of non-infringement. Fenner insisted "personal identification numbers" meant device-specific, not personal, despite the specification stating "personal identification numbers are not associated with any particular communications unit or physical location but are associated with individual users," and arguing the same to overcome prior art during prosecution. A CAFC panel (2013-1640) affirmed.

In Bard v. Gore (CAFC 2014-1114), the CAFC abandons all pretense of equitable rule of law by ignoring its own precedents and exercising biased caprice. In dissent, Judge Newman sharply points this out.

This case returns to the Federal Circuit on appeal of a district court decision on remand from an en banc decision of this court. The issue is willful infringement and its consequences, which this en banc court remanded for de novo determination as a matter of law, vacating the judgment entered on the jury verdict.
The panel majority, while mentioning that willful infringement is now a matter of law, does not undertake the required de novo review... In all events, the question as it relates to willfulness is whether the defense of invalidity could reasonably be raised, not whether it eventually succeeded... On the entirety of the premises and applying the correct legal standards, the judgment of willful infringement cannot stand.
Extensive precedent supports judicial refusal to enhance damages when the case is close and the equities counsel moderation, not punishment... Thus, regardless of whether willfulness was a supportable ruling, the doubling of the damages award is untenable.

Bad Medium

EMD Millipore sued Allpure over its device to put "a medium" into and get out of a jar (6,032,543). It lost in summary judgment, for noninfringement, owing to prosecution estoppel. It's easy to tell how lame the assertion was when the claim construction argument went to the meaning of the term "removed." Hamilton, Brook, Smith & Reynolds represented the plaintiff.

United Video Properties, which owns TV Guide and Rovi, decided it wanted a prime cut of Amazon for infringing 6,769,128 & 7,603,690. Carefully biased claim construction insured noninfringement.  The lynchpin was prosecution estoppel. Ironically, a term was struck ("Internet delivered data") during prosecution that actually broadened claim scope. But of course, with Amazon being the target, the court skewed claim construction to get Amazon off the hook. (CAFC 2013-1396).

But, in response to customer complaints about DataTern, those two software giants filed a DJ against DataTern's assertion. DataTern argued lack of subject matter jurisdiction, to no avail. The fix was in. Summary judgment of noninfringement for all claims of the patents, upheld on appeal. The district court had allowed that to apply to all SAP products, but the CAFC (2013-1184) pared that back to the single product in dispute.

The Greed Gene

Bayer CropScience sued Dow Agrosciences over a claim to bogus genetics. Its assertion was found not infringed; affirmed on appeal. (CAFC 2103-1002)

When the inventors applied for the patent at issue, they had sequenced one gene coding for one enzyme, using a test purportedly capable of finding other, similar genes. In writing its claims, the owner - now Bayer CropScience AG - decided to claim a broad category based on the function of the particular enzyme, defining the category by using a term with an established scientific meaning. In doing so, Bayer got ahead of the science: experiments had not confirmed that the term even applied to the particular enzyme whose gene Bayer's inventors had sequenced. Soon science showed that it did not, and Bayer knew as much years before its patent issued - but did not change its claim language. When it ultimately sued Dow AgroSciences for infringement, Bayer recognized that the term used, in its established scientific meaning, did not cover the accused product (itself different from the particular enzyme whose gene Bayer's inventors had sequenced), so it argued for a broad functional claim construction.

The reckless disregard for the law continues at the CAFC. In Commil v.

In Aristocrat v. International Game (CAFC 2010-1426), there was no direct infringement of gaming machine method claims because the accused infringer didn't control a player's actions. Bad claims drafting was the root problem here. Many prosecutors don't understand how claims are treated in litigation, as in this instance. On the finer point of indirect infringement, the CAFC noted inattention all around: "neither the parties, nor the district court in its summary judgment order, expend significant time on the question of indirect or induced infringement." The district court found non-infringement based upon outdated case law. (The CAFC and SCOTUS substantially change patent law willy-nilly on an irregular basis.) Current law of indirect infringement, under the Akamai precedent, is based upon the notion of a hypothetical "single party would be liable as a direct infringer." With all the facts and law before it, but too inattentive to do its job properly, the CAFC remanded for the district court to figure it out, while giving the law firms involved another welcome boost for more fees to their clients.

Inequitable Estoppel

Bumper Boy asserted animal collar patents that the district court denied on non-infringement against Radio Shack via equitable estoppel, as Bumper Boy wrote a threatening letter, then did nothing for years. On appeal (CAFC 2012-1233), a 2-1 decision highlighted the often capricious court interpretation of the law in this country. A CAFC panel majority: 1) found that Bumper Boy mysteriously eluded equitable estoppel on a CIP even though "these claims do not draw on any new matter"; 2) completely ignored Radio Shack's invalidity arguments, contrary to law (ostensibly for not filing a cross-appeal, when it wasn't necessary. As the dissent pointed out: "the prevailing party need not file a cross-appeal in order to defend a judgment in its favor on any ground that is supported by the record.") Dissenting Judge Newman was rightly disgusted with colleagues Moore and Reyna.

In Move v. Real Estate Alliance (CAFC 2012-1342), Move duped the district court by having the judge whitewash non-infringement. On appeal, a CAFC panel found "the district court failed to conduct an indirect infringement analysis," as Move may have induced infringement: "knew of the asserted patent and performed or knowingly induced the performance of the steps of the claimed methods, and that all of those steps were in fact performed." Under the controversial Akamai precedent, "liability under § 271(b) may arise when the steps of a method claim are performed by more than one entity, provided that the other requirements for inducement are met."

Failing to locate SEB's patent, the attorney issued an opinion letter stating that Pentalpha's deep fryer did not infringe any of the patents that he had found.

After trial, the district court found the case "exceptional" under 35 U.S.C. § 285 and awarded treble damages, attorneys' fees, interest, and costs to Wordtech." The only appeal challenge was for the liability verdicts against two INSC employees.

Database monolith Oracle tried to put a DJ hurt on 5,894,554 as invalid and/or unenforceable. Patent owner epicRealm counterclaimed infringement, then passed the torch to Parallel Networks to carry on. '554 goes to "efficiently managing dynamic web page requests. Specifically, the claimed invention seeks to lighten a web server's processing load by allowing it to off-load dynamic web page requests to one or more page servers."

Beginning its enforcement campaign with the beginning of the alphabet, Silicon Graphics sued ATI and AMD, ultimately for infringing 6,650,327, which claims pipelined floating point graphics calculations. Two other patents had been asserted, but summary judgment in favor of defendants wiped the litigation of those. Summary judgment of non-infringement, as well as a district court finding that a Microsoft license covered part of the action, wiped '327's assertion. But the counterclaim case proceeded to trial, where the patent was found not invalid. Then, naturally, appeal from both sides. Besides claim construction and infringement, a look herein at exhausting defenses and counterclaims.

Dun In

Judson A. Bradford had some ideas for collapsible shipping containers. So he patented. 5,725,119 came first. Then 6,230,916, a divisional of '119. 6,540,096 was a CIP of '916. Enforcement went nowhere: noninfringement. But the CAFC revived Bradford's prospects owing to a too-narrow claim construction. Of particular interest in this case is that Bradford damned himself in the '096 CIP having benefit of the earlier '119 parent prior date.

Global Locate took SiRF and others to the ITC to stop the defendants from importing products infringing six of its GPS patents, which claim methods for improving signal reception. Global Locate prevailed. The defendants appealed. At issue were standing, infringement, and whether GPS-based methods were patentable subject matter under the Bilski standard.

Close-call patent litigation cases are not unusual, but many are exercises in denial. In this episode, Bid for Position bid for doggedness over 7,225,151, which claims a method for conducting a continuous auction. Having lost on non-infringement by a clear-cut claim construction, appeal makes Bid's grasping lawyers look doggedly witless. The not-so-thin line between advocacy and asininity is traversed again.

i4i Review Redux

Microsoft has prevailed upon the CAFC to rehear, en banc, only the willfulness portion of its affirmation of the district court ruling in i4i v. Microsoft. In other words, the CAFC cut Microsoft a break, probably because the CAFC wants another bite at cleaning up the willfulness standard. A revised CAFC ruling was issued today that takes out the sentence: "Microsoft does not challenge the jury instructions on willfulness or the sufficiency of the evidence supporting the jury's willfulness finding," and adds a section on willfulness to its revised ruling.

Trading Technologies sued eSpeed and Ecco for infringing 6,772,132 & 6,766,304, which go to displaying "static price levels" on a computerized board for commodity trading. One service product infringed, but others literally did not, and applying the doctrine of equivalents was proscribed. Defenses to indefiniteness and inequitable conduct went nowhere, as did on-sale bar (§ 102(b)) based on a provisional priority date. Affirmation on appeal toted up dynamic case law quotes, not on sale, but ones that litigators must buy.

Deep Fryer

SEB sued Montgomery Ward and others for infringing 4,995,312 by selling a cheap deep fryer manufactured by Pentalpha. Speedy justice meant that getting to trial took a mere seven years, whereupon a jury found willful infringement, awarding $4.65 million in damages, which the district court judge hence cut by $2 million. The district court had awarded enhanced damages and attorneys' fees to SEB, but then snatched them back in light of the 2007 CAFC Seagate ruling that willfully gutted willfulness. Herein, a tale of disingenuity, and an appeal decision greasing understanding of inducing infringement.

Going Up

5,689,094 claims personal recognition that tells an elevator where to go. Patent owner Schindler Elevator tried to get a lift over Otis Elevator, but Otis got a summary judgment of noninfringement by construction of claim, which was a shame, because, on appeal, the district court took the blame. The CAFC told the district court where to go, while leaving the final destination indefinite.

Unfried Chicken

Restaurant Technologies (RTI) sued Jersey Shore Chicken for infringing 5,249,511, which claims a system for supplying and disposing of cooking oil in restaurant fryers. If RTI had a good prosecutor, the patent wouldn't have read like a product manual, with too few embodiments, especially for means-plus-function claims. Herein, RTI gets fried pursuing denial to a bitter end.

i4i sued Microsoft for a pissant feature in Word: editing custom XML. But to i4i's business, the feature was puissant. A seven-day trial found Microsoft willfully infringing a valid patent, with a jury award of $200 million. "Although statutorily authorized to triple the jury's damages award because of Microsoft's willful infringement, the district court awarded only $40 million in additional damages. It also granted i4i's motion for a permanent injunction." The inevitable appeal, widely expected to go more Microsoft's way than not, did not. Procedural fumbling by supposedly the best lawyers money can buy sold Microsoft short. Herein, CAFC case law heavy on burden and sufficiency, in a case practically covering the gauntlet of patent enforcement.

Experts are the litigation equivalent of hired guns. They are only as good as the guidance given by the attorneys providing their payday on what bullets to shoot where. A case in point is Intellectual Science and Technology v. Sony. 5,748,575, one of five patents left standing on appeal, claims concurrent reading of computer CDs. The district court pitched the case on summary judgment for non-infringement after the plaintiff's expert failed to convince, as his declaration was "merely conclusory." The appeals court gave a lesson in how an expert ought to spurt.

So Unlike Concrete

In an extremely messy patent case involving claim construction (and correction), noninfringement, invalidity, laches, indefiniteness, trade secrets, and topped with several business torts, Ultimax Cement had its quick-set concrete patents crumble by a sledgehammer summary judgment at district court, and so Ultimax sought repair at the CAFC. The foundation of the patent problem: lack of careful proofreading by the prosecutor.

Actually Factual

Source Search Technologies (SST) sued LendingTree over 5,758,328, which claims an online vending system employing request for quote (RFQ) posting to select potential vendors, to which the vendors respond. "The '328 patent claims to solve the "too much" or "too little" information problem commonly associated with running searches over a network or system." The asserted claims were found infringed but obvious, thus invalid, in summary judgment. The appeal, narrowed to a single claim (14), let the CAFC panel reiterate its caution to district courts: be not hasty in granting summary judgment if the scent of "genuine issues of material fact" is in the air.
