The U.S. Court of Appeals for the Federal Circuit (CAFC) on Thursday, March 7, vacated a decision of the Patent Trial and Appeal Board (PTAB) that had held unpatentable certain claims to CoolIT Systems, Inc.’s patent. U.S. Patent 9,057,567 is titled “Fluid Heat Exchange Systems” and is directed to a system for fluid heat transfer to cool electronic devices. On appeal to the CAFC, CoolIT argued that the PTAB erred in construing one of the claim terms, “matingly engaged” and that even under the PTAB’s construction, the asserted prior art did not meet the matingly engaged limitation.

This week was an above-average one for patent filings in both the Patent Trial and Appeal Board (PTAB) and in district courts. The PTAB had two new post grant review (PGR) petitions and 39 new inter partes review (IPR) petitions, for a total of 41 new filings. And the district court also had heightened activity with 75 new filings.

The U.S. Court of Appeals for the Federal Circuit (CAFC) issued a precedential decision today reversing the Western District of Texas district court’s indefiniteness analysis and explaining that it improperly found a contradiction between two claim limitations to arrive at its indefiniteness holding. Amperex Technology Limited filed an action seeking declaratory judgment of noninfringement and challenged the validity of certain claims of Maxell, Ltd.’s U.S. Patent No. 9,077,035 for a rechargeable lithium battery and Maxell asserted infringement of the patent in a separate action. The two actions were consolidated in the Western District of Texas and the court ultimately held that two of the “wherein” clauses of the sole independent claim 1 of the ‘035 patent contradicted one another.

On March 5, the U.S. Court of Appeals for the Federal Circuit (CAFC) issued a precedential decision in Pfizer Inc. v. Sanofi Pasteur Inc. affirming lower rulings by the Patent Trial and Appeal Board (PTAB) that invalidated Pfizer’s patent claims and denied motions to amend (MTA). Although the Federal Circuit vacated the PTAB’s MTA denials with respect to two patent claims, the ruling adds new contours to the appellate court’s case law on obviousness in ways that could affect companies that are patenting chemical inventions with claimed numerical ranges.

For better or worse, anyone can be sued for any reason—even reasons that are completely fictitious and based on allegations that are entirely false. Several cases have recently caused me to ask a simple question: Can something actually be evidence if it is false? I’ve had a few people respond, some thoughtful and others intentionally dense. “Of course, something that is false is evidence,” one person recently told me. “It is up to the trier of fact to determine what is false, and that which is false is clearly evidence to be considered.”

On February 26, the U.S. Court of Appeals for the Federal Circuit issued a precedential decision in Freshub, Ltd. v. Amazon.com, Inc., affirming a ruling by U.S. District Judge Alan Albright of the Western District of Texas in the face of appeals from both parties to the case. The Federal Circuit left the lower ruling intact after finding that the record developed at trial did not establish clear error with regards either to Freshub’s patent infringement allegations or Amazon’s inequitable conduct defense.

It was an average week all around with 31 new patent filings at the Patent Trial and Appeal Board (PTAB) – all inter partes reviews (IPRs) – and 67 new filings in district court. The bulk of this week’s new PTAB filings (a total of 19) were petitions challenging patents owned and asserted by Entropic Communications LLC [associated with SoftBank Group Corp.] (discussed further below). Other notable filings include petitions challenging patents held by Softex [associated with SoftBank Group Corp.], Dental Imaging Technologies [associated with Envista Holdings Corporation], Resonant Systems [d/b/a RevelHMI], Immersion Corp, and Dsm IP Assets BV [associated with DSM-Firmenich AG].

The most striking (and embarrassing) mistake of law in modern patent law history occurred in the case of eBay Inc. v. MercExchange, 347 U.S. 388 (2006). This mistake led to an alarmingly incorrect outcome and a monumental disruption of U.S. innovation policy…. The traditional and longstanding remedy for trespass on a patent property right is a permanent injunction. By making removal of an established infringer/trespasser optional in eBay, the Supreme Court vastly undercut and devalued every patent’s exclusive right. This erroneous outcome is a cataclysmic policy error, but that policy miscarriage is not itself the embarrassing error of law.

On February 20, the U.S. Supreme Court issued an order list that denied petitions for writ of certiorari filed in at least five intellectual property cases. While none of these cases induced large numbers of amici to ask the Court to grant cert, they do represent several current issues in IP law that remain unaddressed. From the use of joinder to evade time-bar limits in patent validity proceedings to the service of process required for a grant of preliminary injunction, the Court’s cert denials leave several open questions with which the patent and trademark community will likely grapple.

On February 5, 2024, the U.S. Court of Appeals for the Federal Circuit (CAFC) held its en banc oral argument to reconsider the obviousness test for design patents. Overall, the many judges’ questions indicated a hesitancy to change the current law, as they expressed concern with positions advanced by the patent challenger. Listening to the argument, it became instantly clear that the designer’s voice was missing from the arguments of both parties. The judges had deeply probing and important questions that need the input of a design professional. As an experienced design professional, I penned this article to highlight the designer’s voice by providing answers to several critical questions posed by the court during oral argument.

On February 16, the U.S. Court of Appeals for the Federal Circuit issued a pair of precedential rulings in Promptu Systems Corp. v. Comcast Cable Communications, LLC, vacating a final judgment of infringement after reversing part of the district court’s claim construction rulings. The entire U.S. patent community, however, should take notice of the Federal Circuit’s sua sponte order informing future litigants that evading briefing limits by incorporating much larger documents by reference will likely result in sanctions.

It was an average week for patent filings at the Patent Trial and Appeal Board (PTAB) and an above-average week in district courts, with 72 district court complaints filed and 18 new PTAB petitions—one petition for Post Grant Review (PGR), and 17 for Inter Partes Review (IPR). At the PTAB, a number of challenges were filed, including two IPRs by Tesla challenging patents owned by Iqar Inc, four IPRs by Dish challenging patents owned by Entropic Communications LLC (associated with Fortress), two IPRs by Microsoft challenging patents owned by Interdigital Patent Holdings Inc (associated with InterDigital Inc.), and two IPRs by Juniper Networks challenging patents owned by Monarch Networking Solutions LLC (associated with Acacia Research Corporation).

The U.S. Court of Appeals for the Federal Circuit (CAFC) today held that certain claims of a patent for a system to protect against identity theft and fraud were invalid for indefiniteness. Judge Schall dissented-in-part, explaining that he would not have found the claims indefinite based on the intrinsic evidence. U.S. Patent No. 9,361,658 is owned by Mantissa Corporation and is titled “System and Method for Enhanced Protection and Control Over the Use of Identity.” Mantissa sued First Financial Corporation and First Financial Bank, N.A. in the U.S. District Court for the Northern District of Illinois, alleging infringement of certain claims. The parties mainly disputed two terms during claim construction: (1) “transaction partner” and (2) “OFF.” The district court relied on First Financial’s expert testimony to conclude that “transaction partner” was indefinite, after finding that the expert used was a person of ordinary skill in the art (POSA).

On February 8, the U.S. Court of Appeals for the Federal Circuit issued a precedential decision in Weber, Inc. v. Provisur Technologies, Inc. that vacated rulings by the Patent Trial and Appeal Board (PTAB) nixing validity challenges by American grill maker Weber against Provisur’s commercial food slicer patent claims. The Federal Circuit reversed the PTAB on claim construction and also found that the Board misapplied CAFC precedent on the level of public dissemination required before printed publications can qualify as prior art.

It was a busy week at the Patent Trial and Appeal Board (PTAB) with 40 new filings—all inter partes review (IPR)—and an average week in the district courts with 51 new filings. The bulk of new PTAB filings can be attributed to a few petitioners challenging multiple patents held by one patent owner (and all asserted in parallel district court litigations). For example, Apple continued its filings against Carbyne Biometrics LLC [associated with Bjorn Markus Jakobsson] patents, adding another five petitions against four patents to the two filed earlier this month
