Justia U.S. Federal Circuit Court of Appeals Opinion Summaries

The plaintiffs in this case, owners of a patent involving genetically engineered host cells containing recombinant DNA sequences, accused the defendants of infringing multiple claims of their patent. The technology at issue centers on human-made host cells that include a recombinant nucleic acid molecule encoding a specific adeno-associated virus (AAV) capsid protein, along with a heterologous non-AAV sequence. These recombinant molecules are created by artificially combining genetic material from different species, a process that does not occur in nature. The patented host cells are used in developing gene therapy products, including a product for treating Duchenne muscular dystrophy.The United States District Court for the District of Delaware reviewed cross-motions for summary judgment on the issue of patent eligibility under 35 U.S.C. § 101. The district court concluded that the asserted claims were ineligible for patent protection, reasoning that they were directed to a natural phenomenon. The court analogized the claims to those at issue in Supreme Court cases such as Funk Brothers Seed Co. v. Kalo Inoculant Co. and Association for Molecular Pathology v. Myriad Genetics, Inc., finding that merely combining natural sequences did not make the claimed invention patentable. The district court held that the claims lacked an inventive concept and granted summary judgment in favor of the defendants.The United States Court of Appeals for the Federal Circuit reviewed the decision de novo. The appellate court held that the patented host cells are not naturally occurring and possess markedly different characteristics from any product of nature, consistent with the Supreme Court’s guidance in Diamond v. Chakrabarty and Myriad Genetics. The Federal Circuit concluded that the claims are not directed to a natural phenomenon and are therefore patent-eligible under § 101. The court reversed the district court’s judgment and remanded the case for further proceedings. View "REGENXBIO INC. v. SAREPTA THERAPEUTICS, INC. " on Justia Law

This case concerns a patent dispute involving input devices for computers. The plaintiff, Genuine Enabling Technology LLC (GET), claimed that Sony’s PlayStation 3 and 4 controllers and consoles infringed several claims of U.S. Patent No. 6,219,730. The patent addresses the problem of limited computer resources by combining data streams from multiple input devices, such as keyboards and sensors, into a single stream. The contested claims include a means-plus-function limitation called “encoding means for synchronizing,” which requires synchronizing two input streams and encoding them into a combined data stream.The U.S. District Court for the District of Delaware handled the case initially. It interpreted the “encoding means” as a means-plus-function limitation and identified logic block 34 in Figure 4A of the patent as the corresponding structure. During litigation, GET’s expert, Dr. Fernald, failed to address most of the elements in logic block 34 when analyzing infringement, focusing primarily on the bit-rate clock signal. The district court excluded Dr. Fernald’s testimony on structural equivalence and ultimately granted Sony summary judgment of noninfringement, finding GET had not raised a genuine issue of material fact regarding infringement.The United States Court of Appeals for the Federal Circuit reviewed the district court’s grant of summary judgment de novo. The Federal Circuit affirmed the lower court’s decision, holding that GET’s infringement analysis was deficient because it did not adequately account for the full structure of logic block 34 required by the patent specification. The court emphasized that GET failed to explain why it was permissible to omit certain elements from its equivalence analysis. Thus, GET lacked sufficient evidence for a reasonable jury to find infringement. The district court’s exclusion of expert testimony and summary judgment were affirmed.

The dispute centers on a patented pre-lit artificial tree owned by Willis Electric Co., Ltd., which features separable, modular trunk portions that mechanically and electrically connect to one another, enabling attached lights to illuminate automatically regardless of trunk orientation. The prior art required separate mechanical and electrical connections, but Willis’ patent integrates both functions in a single step. Willis accused Polygroup of infringing claim 15 of its patent, specifically targeting Polygroup trees with the “Quick Set” feature that establishes simultaneous mechanical and electrical connections.After Willis initiated the lawsuit in the United States District Court for the District of Minnesota, Polygroup filed multiple inter partes review petitions at the Patent Trial and Appeal Board (PTAB) challenging various claims of Willis’ patent. The PTAB upheld claim 15, and the United States Court of Appeals for the Federal Circuit affirmed that finding. The district court proceedings continued with only claim 15 at issue. Polygroup filed a Daubert motion to exclude Willis’ damages expert, which was denied. At trial, the jury found claim 15 infringed and not invalid, awarding Willis over $42 million in damages. Polygroup then moved for judgment as a matter of law (JMOL) on obviousness and a new trial on damages, but the district court denied both motions.The United States Court of Appeals for the Federal Circuit reviewed the district court’s denial of JMOL and the motion for a new trial. The court held that substantial evidence supported the jury’s finding that a skilled artisan would not have been motivated to combine prior art with coaxial barrel connectors as claimed in claim 15, thus affirming nonobviousness. The court also held that the district court did not abuse its discretion in admitting the damages expert’s testimony, finding the methodology sufficiently reliable under Rule 702. As a result, the Federal Circuit affirmed the district court’s judgment in all respects. View "WILLIS ELECTRIC CO., LTD. v. POLYGROUP LTD." on Justia Law

The dispute centers on whether imported plastic shelf dividers containing magnets are subject to U.S. antidumping and countervailing duty orders covering raw flexible magnets from China. Fasteners for Retail, Inc. imports shelf dividers composed of flexible magnets bonded to rigid plastic, which makes the magnets inflexible. The United States Department of Commerce had previously issued duty orders with scope language covering certain flexible magnets, regardless of shape, color, or packaging. Fasteners for Retail requested a scope ruling from Commerce to clarify whether their shelf dividers fell within the scope of these orders.Commerce issued a final scope ruling, finding that although the plain language of the duty orders might appear to include Siffron’s shelf dividers, prior scope rulings and interpretative sources (known as (k)(1) sources) provided further guidance. Based on these sources, Commerce determined that magnets rendered inflexible by attachment to other materials, such as plastic, are not included within the term “flexible magnets” under the duty orders. The United States Court of International Trade reviewed Commerce’s ruling and upheld it, finding Commerce’s determination reasonable and supported by substantial evidence.The United States Court of Appeals for the Federal Circuit reviewed the case de novo, applying the same standard as the Trade Court. The court held that Commerce has discretion under the current regulations to consult (k)(1) sources in interpreting scope language regardless of apparent ambiguity. The court concluded that Commerce’s determination that Siffron’s shelf dividers are not “flexible magnets” under the duty orders was supported by substantial evidence and in accordance with law. Therefore, the Federal Circuit affirmed the judgment of the Court of International Trade, sustaining Commerce’s scope ruling that the shelf dividers are not subject to the duty orders.

This case involves a challenge to the validity of a patent owned by DivX, LLC, which claims systems and methods for streaming partly encrypted media content. DivX sued Netflix, Inc. for patent infringement, leading Netflix to petition for inter partes review (IPR) before the United States Patent and Trademark Office’s Patent Trial and Appeal Board (PTAB). Netflix argued that the patent’s claims would have been obvious in view of specific prior-art references. The dispute centered on the proper construction of a claim limitation relating to the location of "encryption information" within the system described by the patent.After the IPR was instituted, the Patent Trial and Appeal Board first issued a final written decision holding that Netflix had not shown the claims were unpatentable, basing its conclusion on issues unrelated to claim construction. Netflix appealed that decision to the United States Court of Appeals for the Federal Circuit, which vacated and remanded. On remand, the Board adopted DivX’s proposed claim construction, holding that the limitation required the encryption information itself to be located within the requested portions of the selected stream of protected video, and again found in favor of DivX. Netflix appealed again.The United States Court of Appeals for the Federal Circuit reviewed the Board’s claim construction de novo. The appellate court held that the Board erred in its construction of the disputed limitation. The correct construction, the court explained, is that only the encrypted portions of the video frames, not the encryption information, must be located within the requested portions of the selected stream. The court found that, under this construction, the asserted prior art meets the limitation. The Federal Circuit therefore reversed the Board’s claim construction, vacated its decision, and remanded for further proceedings. View "NETFLIX, INC. v. DIVX, LLC " on Justia Law

Several technology companies challenged instructions issued by the Director of the United States Patent and Trademark Office (PTO) that guided the Patent Trial and Appeal Board (Board) in deciding whether to institute inter partes review (IPR) proceedings. These instructions, known collectively as the NHK-Fintiv instructions, outlined factors for the Board to consider when parallel patent litigation was occurring in district court. The challengers argued that these instructions resulted in too many denials of IPR petitions and were contrary to law, arbitrary and capricious, and issued without the required notice-and-comment rulemaking under the Administrative Procedure Act (APA).The United States District Court for the Northern District of California initially found all challenges to the PTO’s instructions to be judicially unreviewable. On appeal, the United States Court of Appeals for the Federal Circuit previously held that while the challenges based on statutory and arbitrary-and-capricious grounds were unreviewable, the claim regarding the lack of notice-and-comment rulemaking could proceed. On remand, the district court determined that the instructions were exempt from notice-and-comment requirements because they were “general statements of policy,” not substantive or legislative rules.The United States Court of Appeals for the Federal Circuit reviewed the district court’s decision de novo. The court agreed that the Director’s instructions were general statements of policy exempt from notice-and-comment rulemaking under 5 U.S.C. § 553(b). It emphasized that there is no statutory right to IPR institution, that the instructions do not bind the Director, and that the Director retains unreviewable discretion to institute or deny IPR. The court found that none of the legal standards or precedents cited by the challengers required a different result, and it affirmed the district court’s judgment rejecting the APA-based challenge.

The petitioner received a Prevnar 13 pneumococcal conjugate vaccine and soon after began experiencing symptoms that ultimately led to a diagnosis of Guillain-Barré Syndrome (GBS). He sought compensation under the National Vaccine Injury Compensation Program, alleging that the vaccine caused his condition. To support his claim, he presented expert testimony advancing a molecular mimicry theory, arguing that components of the vaccine could trigger an autoimmune response resulting in GBS. The government countered with its own expert, disputing this causation theory.A special master in the United States Court of Federal Claims evaluated the evidence and found that the petitioner failed to prove, by a preponderance of the evidence, that the vaccine can cause GBS. The special master determined that key elements of the petitioner’s expert’s theory lacked support from reliable scientific literature and that the evidence did not sufficiently establish a causal connection. As a result, the special master denied compensation. The United States Court of Federal Claims reviewed and affirmed the special master’s decision.The United States Court of Appeals for the Federal Circuit reviewed the case. It held that the special master did not require the petitioner to provide direct medical literature establishing causation, which would have been contrary to the standard set forth in Althen v. Secretary of Health & Human Services, 418 F.3d 1274 (Fed. Cir. 2005). Instead, the special master properly considered the absence of supporting literature as one factor in evaluating the reliability of the causation theory, consistent with governing law. The Federal Circuit affirmed the Claims Court’s decision, noting concern about inconsistent outcomes among special masters on similar facts but finding no legal error in this case’s resolution.

Two companies that manufacture activated carbon honeycombs, used in automotive emission control systems, became embroiled in a legal dispute. One company holds a patent covering certain dual-stage fuel vapor canister systems, but not honeycombs used in air-intake systems. The other company began marketing a competing honeycomb product, prompting a patent infringement lawsuit. In response, the defendant challenged the validity of the patent, argued non-infringement, and asserted counterclaims alleging antitrust violations—specifically, that the patent holder unlawfully tied licenses for the patent to the purchase of its unpatented honeycomb products.The United States District Court for the District of Delaware first granted summary judgment that the patent was invalid due to prior invention. It then denied both parties’ motions for summary judgment on the antitrust and tortious interference counterclaims, finding a factual dispute about whether the honeycomb products had substantial non-infringing uses. At trial, the jury found the patent holder liable for unlawful tying under federal antitrust law, concluding that it had conditioned patent licenses on customers buying its honeycombs, and awarded significant damages. The district court denied the patent holder’s motions for judgment as a matter of law and for a new trial, confirming the jury’s findings that the honeycombs were staple goods with substantial non-infringing uses and that the conduct was not protected by immunity doctrines.On appeal, the United States Court of Appeals for the Federal Circuit affirmed the district court’s judgment. The Federal Circuit held that substantial evidence supported the jury’s findings that the honeycomb products had actual and substantial non-infringing uses, making them staple goods and removing the patent holder’s statutory defense against antitrust liability. The court also rejected the argument that the patent holder’s conduct was immunized from antitrust scrutiny, and upheld the damages award, finding no error in the district court’s rulings or the jury’s determinations.

GoTV Streaming, LLC owned three related patents that describe a system in which a server receives a content request from a wireless device, tailors the content to that device’s capabilities (such as screen size), and sends the modified content to the device for display. The patents were designed to reduce the burden of developing unique applications for each device type. Instead, the server uses generic templates and custom configurations that are then tailored to the specific device’s needs.The United States District Court for the Central District of California initially dismissed GoTV’s claims for induced infringement, holding that such claims require the defendant’s knowledge of the patents before the lawsuit. The court also denied Netflix’s motion that the patents were ineligible under 35 U.S.C. § 101, finding the claims were not directed to abstract ideas. The court later found all claims of the ’865 patent indefinite and invalid, adopted some of GoTV’s proposed claim constructions, and denied GoTV’s motions to exclude certain Netflix damages evidence. At trial, the jury found Netflix infringed only one patent and awarded GoTV $2.5 million in damages. The district court denied GoTV’s post-trial motions, including for retrial on damages and for prejudgment interest predating the complaint.The United States Court of Appeals for the Federal Circuit reviewed the case. It reversed the district court’s indefiniteness finding for the ’865 patent and adopted GoTV’s claim construction. However, it held that all asserted claims were patent-ineligible under § 101 because they were directed to the abstract idea of using a generic template tailored for a user’s device without reciting an inventive concept. The Federal Circuit reversed the district court’s judgment for GoTV, ordered judgment for Netflix, and vacated the district court’s rulings on inducement and damages evidence.

The United States Department of Commerce issued a request for proposals seeking enterprise-wide information technology services. After evaluating numerous proposals, the agency announced fifteen presumptive contract awardees. CAN Softtech, Inc. (CSI) and other unsuccessful offerors challenged the awards, alleging flaws in the evaluation process. The agency responded by reevaluating the proposals multiple times, making adjustments to the technical evaluation team, and ultimately reissuing awards to the same fifteen companies. Each time, CSI and others filed new or amended bid protests, contending that the agency’s corrective actions and reevaluations were improper.The United States Court of Federal Claims initially found the agency’s evaluation of CSI’s proposal arbitrary and capricious and enjoined performance of the contracts pending reevaluation. After further corrective action by the agency, including terminating awards and issuing new evaluations, the trial court determined that the agency’s final evaluation and contract awards were rational and supported by the record. The court considered the agency’s process for reevaluation and corrective action to have satisfied procedural requirements, and rejected CSI’s argument that the agency needed to seek voluntary remand before taking corrective action.The United States Court of Appeals for the Federal Circuit reviewed the trial court’s judgment de novo. The court held that administrative agencies possess inherent authority to terminate contract awards and take unilateral corrective action in response to bid protests, so long as they act within statutory and procedural bounds and avoid arbitrary or capricious conduct. The court also determined that the agency’s actions in this case did not violate the Administrative Procedure Act and were not arbitrary, capricious, or an abuse of discretion. The Federal Circuit affirmed the trial court’s denial of CSI’s bid protest. View "SYNEREN TECHNOLOGIES CORP. v. US " on Justia Law
