CAFC Says Dyfan Claim Limitations are Not Invalid Due to Means-Plus-Function Format

Last week, the U.S. Court of Appeals for the Federal Circuit (CAFC) reversed and remanded a decision by the U.S. District Court for the Western District of Texas that Dyfan, LLC’s claims were invalid as indefinite. The CAFC concluded that the disputed claim limitations were not drafted in means-plus-function format, and therefore 35 U.S.C. § 112 ¶ 6 did not apply. Patent owner Dyfan sued Target Corp. for infringement of various claims of U.S. Patent Nos. 9,973,899 and 10,194,292. Following a claim construction hearing, the district court found that the disputed (1) “code”/“application” limitations and (2) “system” limitations of the patents-in-suit were invalid as indefinite. Specifically, the district court found that: (1) these claim limitations of the patents-in-suit are in means-plus-function format under Section 112 ¶ 6 and (2) the specification does not disclose sufficient structure corresponding to the recited functions. Dyfan subsequently appealed.

Lessons from Junker v. Medical Components, Inc. on Commercial Offers for Sale Invalidating a Patent

Recently, the U.S. Court of Appeals for the Federal Circuit (CAFC) further explained the “on-sale” bar in Junker v. Medical Components, Inc., Case No. 2021-1649 (Feb. 10, 2022). As previously reported here, the case hinged on whether a letter between Larry Junker’s business partner and Boston Scientific Corporation (BSC) was a “commercial offer for sale” before the one-year grace period took effect. The CAFC held that all necessary terms for a commercial offer were present in the letter, and therefore, the letter qualified as a commercial offer for sale invalidating Junker’s patent.

CAFC Upholds PTAB Precedential Opinion Panel Decision Despite ‘Problematic’ Reasoning

On March 24, the U.S. Court of Appeals for the Federal Circuit (CAFC) affirmed a Patent Trial and Appeal Board (PTAB) Precedential Opinion Panel’s (POP’s) decision allowing patent owner DynaEnergetics Europe GmH to amend its claims, and also affirmed the PTAB’s decision that the original claims of the patent were unpatentable. Hunting Titan, Inc. petitioned for inter partes review of claims 1–15 of the U.S. Patent No. 9,581,422, asserting grounds of unpatentability based on anticipation and obviousness, including allegations that the claims were anticipated by U.S. Patent No. 9,689,223 (Schacherer). The Board instituted trial on all grounds and found all of the original claims unpatentable.

Stinging CAFC Dissent from Denial of Biogen Rehearing Petition Accuses Majority of Muddying Written Description

The U.S. Court of Appeals for the Federal Circuit today denied rehearing and rehearing en banc to Biogen International, which had petitioned the court following a November decision  affirming a district court ruling that Biogen’s patent for a method of treating multiple sclerosis (MS) was invalid for lack of written description. Three judges split from the majority, with Judges Lourie, Moore and Newman dissenting on the denial of en banc rehearing. Judge O’Malley had dissented from the November panel decision, but she retired on March 11, 2022, and only participated in the decision on panel rehearing.

Original Claims to Award-Winning Wireless Mic Tech Found Obvious at CAFC, But Narrowed Claims Upheld

On Friday, the U.S. Court of Appeals for the Federal Circuit (CAFC) agreed with the Patent Trial and Appeal Board’s (PTAB’s) decision that the original claims of Zaxcom’s U.S. Patent No. 9,336,307 for Engineering Emmy® and technical OSCAR award-winning wireless microphone technology were unpatentable as obvious. However, the court upheld the substitute claims Zaxcom had proposed. Zaxcom appealed the PTAB’s decision on the original claims in May of 2020, arguing that the PTAB misconstrued the patent claims and failed to properly consider evidence of industry praise.

CAFC Affirms District Court Finding that Naloxone Patents are Obvious; Newman Dissents

On February 10, the U.S. Court of Appeals for the Federal Circuit (CAFC) affirmed a decision by the U.S. District Court for the District of New Jersey, explaining that the district court did not err in finding several Adapt Pharma patents obvious. The asserted claims relate to U.S. Patent Nos. 9,468,747; 9,561,177; 9,629,965; and 9,775,838 (collectively, the “patents-in-suit”). The patents-in-suit claim methods of treating opioid overdose by intranasal administration of a naloxone formulation, as well as devices for intranasal administration. Naloxone is the active ingredient in Adapt’s NARCANâ Nasal Spray and is an opioid receptor antagonist, thus helping reverse the effects of opioid overdose. The opinion was authored by Judge Kara Stoll; Judge Pauline Newman dissented.

CAFC Corrects District Court’s On-Sale Bar Analysis

The U.S. Court of Appeals for the Federal Circuit (CAFC) today reversed the U.S. District Court for the District of Pennsylvania’s summary judgment that a medical device design patent was not invalid under the on-sale bar. Junker v. Medical Components, Inc. The district court found the patent was infringed and awarded damages in the amount of $1,247,910. But the CAFC held that a letter sent by the inventor’s business partner to Boston Scientific Corporation in 1999 represented a commercial offer for sale of the claimed design.

CAFC Upholds PTAB Ruling that Patents on Autonomous Driving Tech Are Not Obvious

On February 4, 2022, The U.S. Court of Appeals for the Federal Circuit (CAFC) affirmed two decisions of the Patent Trial and Appeal Board (PTAB) on related inter partes reviews (IPRs) brought by Quanergy against Velodyne, explaining that the Board’s decision to uphold the validity of the disputed claims was correct considering the objective evidence provided by Velodyne. Quanergy challenged multiple claims of U.S. Patent No. 7,969,558, covering a lidar-based 3-D point cloud measuring system best known for helping autonomous cars sense their surroundings. In its decisions, the PTAB held that several claims of the ’558 patent are not unpatentable as obvious.

CAFC Orders New Trial on Damages, Clarifies IPR Estoppel Rule in Appeal of Caltech’s $1.1 Billion Win Against Apple and Broadcom

On February 4, in a mixed precedential decision, the U.S. Court of Appeals for the Federal Circuit (CAFC) affirmed, vacated, and remanded in part a decision by the U.S. District Court for the Central District of California in a patent infringement suit filed by the California Institute of Technology (Caltech) against Broadcom Limited, Broadcom Corporation, and Avago Technologies (collectively “Broadcom) and Apple Inc. The suit was related to Caltech’s U.S. Patent 7,116,710 (‘710 patent), U.S. Patent 7,421,032 (‘032 patent), and U.S. Patent 7,916,781 (‘781 patent). The CAFC affirmed the district court’s denial of judgment as a matter of law (JMOL) on infringement because the jury’s verdict of infringement of the declared claims of the ‘710 and ‘032 patents was supported by substantial evidence and the district court’s construction of the claim limitation “repeat” was not erroneous.

O’Malley Dissents from ‘Concerning’ CAFC Ruling that Biogen’s MS Drug Patent is Invalid

The U.S. Court of Appeals for the Federal Circuit (CAFC) earlier today affirmed a district court ruling that Biogen International’s patent for a method of treating multiple sclerosis (MS) was invalid for lack of written description. Judge O’Malley dissented, arguing that the district court clearly erred in its finding that Biogen was judicially estopped from drawing a distinction between clinical and therapeutic effect, and that the entire analysis “might well change” if the case was remanded “for reconsideration of the record with the understanding that the patent is not about clinical efficacy” but therapeutic effect.

Hindsight Bias: An Ovine Survey

The arrival of a U.S. Patent and Trademark Office (USPTO) office action citing no less than six earlier patents directed to various sub-combinations in the features of the main independent claim in an application which I was handling prompted the present note. Readers may recall the decision of Judge Rich In re Winslow 365 F.2d 1017 (C.C.P.A. 1966): “We think the proper way to apply the 103-obviousness test to a case like this is to first picture the inventor as working in his shop with the prior art references — which he is presumed to know — hanging on the walls around him.” However, Boltzmann’s entropy formula S = k log W where S represents entropy, a concept associated with a state of disorder, randomness, or uncertainty, and W represents the number of possible states in the relevant system, leaves an unforgettable impression on those who have studied it. Even if the fields from which the earlier patents might be selected are restricted to relevant general classifications, the number of combinations of six references which might have been collected together from the body of prior art in the relevant technical field randomly and without knowledge of the invention is mind-boggling.

Alice-Insanity (Part One), or Why the Alice-Mayo Test Violates Due Process of Law

The Fifth Amendment of the U.S. Constitution guarantees, inter alia, that no person shall be deprived of property (including intellectual property), without due process of law. For instance, it is settled law that a federal statute may be so arbitrary and capricious as to violate due process. Similarly, it is settled that an administrative agency, e.g., the U.S. Patent and Trademark Office (USPTO), cannot escape the due process of law requirement when processing patent applications. In theory (less in reality), due process of the law extends to judicial as well as political branches of government, and judgments that violate constitutional limitations and guarantees are void or voidable.

CareDx v. Natera: The Latest in Patent Eligibility of Medical Diagnostics

The latest ruling involving patent eligibility of medical diagnostics comes from Chief Judge Connolly of the United States District Court for the District of Delaware in a consolidated case brought by CareDx, Inc. and the Board of Trustees of the Leland Stanford Junior University against Natera, Inc. (Civil Action No. 19-0567-CFC-CJB) and Eurofins Viracor, Inc. (Civil Action No. 19-1804-CFC-CJB). After initially denying the Defendants’ motions for summary judgment of invalidity of the asserted patents under 35 U.S.C. §101 in December 2020, the Court then later denied certification motions for interlocutory appeal and instead ruled sua sponte to reconsider its own denial of summary judgment. Following an evidentiary hearing during which expert testimony was heard, the Court reversed its previous ruling to find all claims of the asserted patents invalid as a matter of law under §101.

Where We Are on AI Inventorship and Where We Should be Heading

The past few years saw a meteoric rise of artificial intelligence (AI) products, services, and applications. AI has evolved from merely a buzzword or a cool new idea to a substantively used tool in a variety of applications, including autonomous driving, natural language processing, drug development, finance and cybersecurity among others. Companies, universities, and inventors world-wide noted the importance of AI and began seeking to patent various aspects of AI technology. Until 2018, these patent applications identified a human inventor who invented a particular aspect of the AI technology. Then, Dr. Stephen Thaler filed a patent application for a food container and a light emitting device that identified an AI, known as DABUS, as an inventor.

CAFC Reverses PTAB Win for St. Jude, Finding Snyders’ Heart Valve Claims Not Unpatentable

On October 5, the U.S. Court of Appeals for the Federal Circuit (CAFC) reversed a decision by the U.S. Patent and Trademark Office’s Patent Trial and Appeal Board (PTAB) that Snyders Heart Valve LLC’s (Snyders) patent claims for an artificial heart valve were unpatentable. The court said the PTAB relied on an erroneous claim construction. The CAFC previously vacated and remanded the appeal after only reaching Snyders’ argument under the Appointments Clause following its decision in Arthrex, Inc. v. Smith & Nephew, Inc. The U.S. government sought certiorari to challenge the remand, and after its decision in United States v. Arthrex Inc. (U.S. Supreme Court, 2021), the Supreme Court vacated the decision of the CAFC and remanded the matter back. Snyders waived the Appointments Clause challenge and asked the CAFC to consider the merits of the case on remand.
