The case involves ParkerVision, Inc. appealing a decision by the Patent Trial and Appeal Board (Board) that invalidated one of its patents, U.S. Patent No. 7,110,444 ('444 patent), owned by ParkerVision, Inc., which relates to wireless local area networks (WLANs) that use frequency translation technology. The Board determined that claim 3 of the patent is unpatentable as obvious in light of prior art. The United States Court of Appeals for the Federal Circuit affirmed the Board's decision. The court found that the Board correctly construed the term “storage element” and did not procedurally err in how it treated certain arguments raised by the parties. The court also found substantial evidence supporting the Board's finding that the patent claim was obvious in light of prior art. The court found no violation of ParkerVision's procedural rights under the Administrative Procedure Act (APA) and no abuse of the Board's discretion in excluding parts of ParkerVision’s sur-reply.

In this case, the United States Court of Appeals for the Federal Circuit considered whether the defendants' Abbreviated New Drug Applications (ANDAs) infringed two patents owned by the plaintiffs. The patents pertained to the use of the drug vortioxetine in the treatment of patients who had previously taken certain other antidepressant medications and had to cease or reduce use due to sexually related adverse events, and for the treatment of cognitive impairment. The defendants were seeking approval to market vortioxetine for the treatment of Major Depressive Disorder (MDD) in adults, a use not covered by the patents. The plaintiffs sought to block the defendants from marketing a generic version of the drug until after the expiration of the patents.The court held that the defendants' ANDA filings did not infringe the plaintiffs' patents. The court found that the defendants' intended use of the drug, for the treatment of MDD in adults, did not infringe the patents which pertained to other specific uses of the drug.Moreover, the court found no induced or contributory infringement. Regarding induced infringement, the court held that the defendants' proposed labels for the drug did not encourage, recommend, or promote an infringing use. Regarding contributory infringement, the court held that the defendants' sale of the drug would have substantial noninfringing uses, thus there would be no contributory infringement.Additionally, the court rejected Lupin's cross-appeal, which challenged the district court's determination that Lupin infringed a patent concerning a process for manufacturing vortioxetine. The court affirmed the district court's construction of the term "reacting" in the patent and its determination of infringement. View "H. LUNDBECK A/S v. LUPIN LTD. " on Justia Law

In a case before the United States Court of Appeals for the Federal Circuit involving VLSI Technology LLC and Intel Corporation, the court examined claims of patent infringement and respective damages. VLSI alleged that Intel had infringed two of its patents, U.S. Patent No. 7,523,373 ("373 patent") and U.S. Patent No. 7,725,759 ("759 patent").The jury found that Intel had indeed infringed both patents and awarded separate damages for each. Intel appealed these decisions. The court affirmed the judgment of infringement of the 373 patent but reversed the judgment of infringement of the 759 patent. The court also vacated the award of damages for the 373 patent and remanded the case for a new trial limited to damages. The court further reversed the denial of Intel's motion for leave to amend to add a license defense.The court's decisions hinged on a number of factors, including the interpretation of the patents, the evidence presented by both parties, and the legal conclusions drawn by the district court. The court's decision underscores the complexity of patent infringement cases and the importance of accurately interpreting and applying patent law. View "VLSI TECHNOLOGY LLC v.

Purdue sued Collegium for infringement of its patent, meant to deter the abuse of opioid analgesics by the inclusion of an aversive agent, Collegium petitioned the Patent Trial and Appeal Board for post-grant review (PGR) of claims 1– 17. The Board found the challenged claims eligible for PGR because the pre-America Invents Act (AIA) 2001 application to which Purdue claimed priority did not contain sufficient written description support for the claimed invention. Under 35 U.S.C. 326(a)(11), the Board had one year to issue a Final Written Decision subject to a six-month extension. In September 2019, Purdue filed a Notice of Bankruptcy. The PGR proceeding and court case were stayed. In October 2019, a six-month extension was approved: “Petitioner should seek any relief it deems appropriate from the Bankruptcy Court.” Neither party sought guidance or an order lifting the stay from the bankruptcy court. The April 2020, extended deadline passed. In July 2020, the bankruptcy court lifted the stay for both proceedings.Rejecting Purdue’s motion to terminate the PGR, the Board concluded that “the AIA’s silence as to a consequence for timely issuing a final written decision does not divest us of our authority” and found claims 1–17 unpatentable for lack of written description and anticipation. The Federal Circuit affirmed. Under Supreme Court precedent, the Board has the authority to issue a Final Written Decision after the deadline proscribed in the statute has passed absent any contrary indication in the language, structure, or legislative history of the statute.

Telefex’s 116 patent. is directed to a method for using a guide extension catheter with a guide catheter. In 2019, Medtronic launched its own allegedly infringing guide extension catheter product, Telescope. Medtronic filed two petitions for inter partes review (IPR) of the 116 patent. The Federal Circuit affirmed the Patent and Trademark Office Patent Trial and Appeal Board in holding that Medtronic had not shown the challenged claims to be unpatentable. In finding that the claimed invention was conceived before the critical date of alleged prior art (Itou), the court determined that the claimed invention was actually reduced to practice before the critical date of Itou and the patent owner diligently pursued work on the invention until its constructive reduction to practice. “In vivo” testing was not required for actual reduction to practice because the claims at issue are method claims reciting “advancing . . . a guide catheter . . . through a main blood vessel to an ostium of a coronary artery.” View "Medtronic, Inc. v.

Cloudbreak’s patent discloses compositions and methods for treating pterygium, an eye condition in which a tumor-like growth extends from the nasal or temporal side of the eye to the cornea, by administering multikinase inhibitors to the eye to inhibit specific growth factors that contribute to tumor growth and hyperemia (i.e., eye redness). The patent discloses that nintedanib in particular “may be one of the most powerful multikinase inhibitors for reducing corneal neovascularization.”In inter partes review, the Patent Trial and Appeal Board held that the petitioner, Allgenesis, failed to prove two claims of the patent are unpatentable. The Federal Circuit dismissed an appeal. Allgenesis failed to establish an injury in fact sufficient to confer standing to appeal. Allgenesis identified no concrete plans to develop and bring to market a nintedanib treatment for pterygium and has not shown its activities will create a substantial risk of infringement or will likely cause Cloudbreak to assert a claim of infringement. The court rejected an argument that Allgenesis suffered an injury in fact based on the Board’s priority determination that will have a preclusive effect on the scope of its pending patent application. Allgenesis has not established that the Board’s decision will have preclusive effect. View "Allgenesis Biotherapeutics Inc. v. Cloudbreak Therapeutics, LLC" on Justia Law

Epoprostenol, a naturally occurring substance, useful for treating cardiovascular diseases, was discovered in the early 1980s and was first brought to market under the brand name Flolan® in 1995. Epoprostenol is unstable in water, it was prepared as a freeze-dried, or lyophilized, powder for use in the Flolan composition. Actelion owns two patents directed to improved epoprostenol formulations that can be reconstituted with commercially available IV fluids and do not require refrigeration after reconstitution until use.” The inventor “unexpectedly found that epoprostenol solution in the presence of an alkalinizing agent, and high pH (>11) is very stable compared to Flolan.” Mylan sought approval to manufacture and sell a generic epoprostenol sodium for injection by filing an Abbreviated New Drug Application (ANDA) with the FDA, containing a certification that the Actelion patents’ claims were invalid or would not be infringed by the ANDA product.The Federal Circuit vacated the district court’s claim construction order with respect to the term “a pH of 13 or higher” and its judgment of infringement. The issue involves understanding what the significant digits are for “a pH of 13.” The district court must address extrinsic evidence explaining how a person of ordinary skill in the art would view the significant digits for a pH value.

In 2011, PersonalWeb sued Amazon in Texas, alleging that Amazon’s S3 technology infringed PersonalWeb’s “True Name” patents. After the court construed the claim terms, PersonalWeb stipulated to dismissal. In 2018, PersonalWeb asserted the same patents against 85 Amazon customers for their use of Amazon S3. Amazon intervened and filed a declaratory judgment action. The customer cases and Amazon’s declaratory judgment action were consolidated. PersonalWeb represented that if it lost its “Twitch” customer case, it could not prevail in the other customer cases. The court stayed the other cases; the Twitch case and Amazon’s declaratory judgment action proceeded. PersonalWeb counterclaimed against Amazon, alleging that Amazon S3 infringed its True Name patents and accused another Amazon product, CloudFront, of infringement.The Federal Circuit affirmed partial summary judgment of non-infringement of the S3 product, based on claim preclusion and summary judgment of non-infringement as to CloudFront because, under the earlier claim construction, PersonalWeb admittedly could not prove infringement. The district court granted Amazon and Twitch attorneys’ fees and costs, 35 U.S.C. 285, determining that the case was exceptional because PersonalWeb’s claims related to Amazon S3 were objectively baseless in light of the Texas Action; PersonalWeb frequently changed positions; PersonalWeb unnecessarily prolonged litigation after claim construction foreclosed its infringement theories; PersonalWeb’s positions regarding the customer cases were unreasonable; and PersonalWeb submitted declarations that it should have known were not accurate. The Federal Circuit affirmed an award of $5,401,625.06, including $5,187,203.99 in attorneys’ fees. View "In re PersonalWeb Techs., LLC" on Justia Law

The 549 and 175 patents disclose microcalorimeters, machines that measure the amount of energy absorbed or released during a chemical reaction between two compounds, specifically an isothermal titration calorimeter (ITC). Malvern’s 782 patent is unrelated to those patents. An examiner rejected various claims of the 782 patent (with an automated ITC) as anticipated by the 968 application, disclosing a prior art “manual ITC system.” The examiner understood the 968 application to disclose an automated ITC system but noted that because the 968 application and the 782 patent had a common assignee, the 968 application might not qualify as prior art under pre-America Invents Act, 35 U.S.C. 103(c)(1). The examiner then withdrew the rejection, finding that the 968 application did not count as prior art. After Malvern acquired the 549 and 175 patents, Malvern sought supplemental examination of the 175 patent under 35 U.S.C. 257.Malvern sued Waters for infringing the 549 and 175 patents. The district court construed the term “pipette guiding mechanism” as a “mechanism that manually guides the pipette assembly.” The Federal Circuit vacated. The claim language and the specification indicate that the term is used broadly in the 549 and 175 patents and refers to a mechanism that guides the pipette assembly either manually or automatically. Merely listing the 782 patent office actions in the IDS of the 175 patent supplemental examination was insufficient to inform the meaning of “pipette guiding mechanism” in unrelated patents.

Divx’s 720 and 515 patents relate to a method for adaptive bitrate streaming of content on a playback device, such as a mobile phone or personal computer. “Adaptive bit rate streaming involves detecting the present streaming conditions (e.g., the playback device’s network bandwidth and video decoding capacity) in real-time and adjusting the quality of the streamed media accordingly.” On inter partes review, the Patent Trial and Appeal Board held that Netflix did not meet its burden of proving challenged claims in the patents unpatentable under 35 U.S.C. 103.Netflix’s appeal argued that the Board failed to address several arguments purportedly raised in Netflix’s petitions. The Federal Circuit found no error in how the Board understood Netflix’s petition arguments and affirmed. It is the petitioner’s burden to make clear when alternative arguments are being presented and to sufficiently expound on each one. The Board should not have to work as hard as Netflix wants to identify all arguments fairly presented in a petition. View "Netflix, Inc. v. DivX, LLC" on Justia Law
