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

Congestive heart failure can be treated by resynchronization therapy, using electrical pacing leads to help keep the two sides of the heart contracting with regularity and in sync. According to Niazi's 268 patent, physicians previously accomplished resynchronization by inserting a catheter into the coronary sinus and its branch veins to place pacing leads on the hearts of patients; it can be “difficult to pass a lead” into the coronary sinus and its branch veins using a catheter. The 268 patent describes a double catheter, comprising an outer and inner catheter, for cannulating the coronary sinus “without significant manipulation.” Niazi sued for patent infringement, accusing combinations of St. Jude’s products of directly infringing the 268 patent and accusing St. Jude of inducing infringement.The Federal Circuit reversed the district court’s determination that all but one of the asserted patent claims are invalid as indefinite; when read in light of the intrinsic evidence, a person of ordinary skill in the art would understand the scope of the claims with reasonable certainty. Niazi failed to prove direct infringement—a necessary element of Niazi’s inducement claim. The court affirmed the entry of monetary sanctions and the exclusion of portions of Niazi’s technical expert and damages expert reports because Niazi failed to disclose predicate facts during discovery. The court upheld the exclusion of portions of Niazi’s damages expert report as unreliable. View "Niazi Licensing Corp. v. St. Jude Medical S.C., Inc." on Justia Law

BioVeris, a Roche entity, owns the patents, which concern immunoassays that exploit electrochemiluminescence (ECL). Meso maintains that a prior owner, IGEN, granted it exclusive rights to the patent claims it now asserts against Roche (which sells instruments and reagent packs for performing ECL immunoassays). Meso sued Roche in the Delaware Court of Chancery in 2010, alleging that Roche breached its 2003 license with IGEN by violating a field restriction. The chancery court determined that Meso was not a party to the 2003 license agreement, such that only BioVeris (IGEN’s successor-in-interest) could enforce the field restriction.In 2017, Roche sought a federal court declaratory judgment that it does not infringe Meso’s rights arising from a 1995 joint venture license agreement. Meso counterclaimed for patent infringement. A jury found that Meso holds an exclusive license to the asserted patent claims, that Roche directly infringed one claim and induced infringement of three claims in other patents, and that Roche’s infringement was willful. It awarded Meso $137,250,000 in damages. The court granted Roche judgment as a matter of law on willfulness, denied Meso’s motions to enhance damages, and rendered a noninfringement judgment with respect to three additional patents on the ground that Meso waived compulsory infringement counterclaims. The Federal Circuit affirmed on direct infringement, reversed on induced infringement, vacated the damages award, remanded for a new trial on damages, and vacated the judgment of noninfringement with respect to three additional patents.

Littelfuse alleged that Mersen infringed its patent, which is directed to a “fuse end cap for providing an electrical connection between a fuse and an electrical conductor.” After the district court construed the patent claims, the parties stipulated to a judgment of non-infringement.The Federal Circuit vacated the judgment and the district court’s constructions of “fastening stem” and “a fastening stem that extends from the mounting cuff and into the second cavity of the terminal that receives the conductor.” On remand, the district court should adjust the construction of those claim terms so as to allow for the independent claims to cover both single-piece and multi-piece embodiments, but the court’s constructions should continue to give meaning to the terms “fastening” and “stem” in the context of the invention and the ordinary meaning of those terms.

Genuine Enabling’s patent, titled “Method and Apparatus for Producing a Combined Data Stream and Recovering Therefrom the Respective User Input Stream and at Least One Additional Input Signal,” discloses the technology for combining data streams that the inventor, Nguyen, conceived when developing a “voice mouse” that conserved computer resources. Genuine sued Nintendo, accusing infringement by the Wii Remote and Wii Remote Plus, the Nunchuk, the WiiU GamePad, the Switch Joy-Con Controller, and the Nintendo Switch Pro Controller..The district court construed the term “input signal,” which appears in all the asserted claims, consistent with the defendants’ proposed construction, and granted the defendants summary judgment of noninfringement.The Federal Circuit reversed. The district court erred in its construction of “input signal.” The Federal Circuit construed the term to mean “a signal having an audio or higher frequency.” Nguyen disclaimed subject matter other than signals below the audio frequency spectrum during prosecution, and the district court further erred in relying on extrinsic evidence to limit the claim scope to signals above 500 Hz.

The patents-in-suit, titled “System for Location-Based Triggers for Mobile Devices,” describe improved systems for delivering messages to users based on their locations. The shared specification discloses a communications system that provides users with information tailored to their particular interests or needs based on their presence within a specified location, such as a shopping center that has different retail stores within it. The district court held the claims invalid as indefinite under 35 U.S.C. 112 based on its view that certain claim limitations are in means-plus-function format and that the specification does not disclose sufficient structure corresponding to the recited functions.The Federal Circuit reversed, holding that the “code”/“application” limitations are not written in means-plus-function format because they would have connoted sufficiently definite structure to persons of ordinary skill in the art.

DynaEnergetics’s patent is directed to a perforating gun used in an oil wellbore to penetrate the well lining and surrounding rock formation in order to provide a flow path for oil into the wellbore from the surrounding rock formation. Titan petitioned for inter partes review of claims 1–15, asserting unpatentability based on anticipation and obviousness. The Board found all of the original claims unpatentable. DynaEnergetics moved to amend the patent to add proposed substitute claims 16–22. Titan opposed the motion, advancing only obviousness grounds. Although Titan did not assert that prior art (Schacherer) anticipated the proposed substitute claims, the Board determined that the original and proposed substitute claims alike were unpatentable as anticipated by Schacherer.The Federal Circuit Precedential Opinion Panel concluded that Titan had not proven by a preponderance of the evidence that proposed substitute claims 16–22 are unpatentable and granted the motion to amend the patent to add the proposed substitute claims. The Federal Circuit subsequently affirmed. Substantial evidence supports the Board’s determination that Schacherer anticipates all of the patent’s original claims. The court rejected Titan’s challenge to the Panel’s decision to vacate the Board’s denial of the motion to amend and argument that the Board has a duty to determine the patentability of the proposed substitute claims based on the entirety of the record.

CSIRO, a research arm of the Australian government, owns six U.S. patents, concerning the engineering of plants, particularly canola, to produce specified oils not native to the plants. After the resolution of jurisdiction and venue issues in an infringement case against BASF and Cargill, the case proceeded to trial on eight claims of the six patents. The parties stipulated to infringement of five patents; the jury found infringement of the sixth. The jury rejected invalidity challenges, including the challenge that the asserted patent claims lacked adequate written-description support. The jury found that BASF co-owned one patent (precluding infringement of that patent) but not the others. The district court ruled that the evidence would not support a finding of willfulness, denied a conduct-stopping injunction, and granted an ongoing royalty on all five patents found infringed.The Federal Circuit affirmed that Eastern District of Virginia venue was proper and affirmed the verdict rejecting the written-description challenge to the claims that are limited to canola plants but reversed as to the broader genus claims. The court agreed that five patents were not co-owned by BASF but reversed the contrary verdict as to the sixth, so that infringement of all valid claims of the six patents is now settled. The court upheld the district court’s refusal to submit willfulness to the jury and its decision on an evidentiary issue concerning past damages but remanded for reconsideration of the remedy.

Almirall’s patent relates to methods of treating acne or rosacea with dapsone formulations that include an acrylamide/sodium acryloyldimethyl taurate copolymer (A/SA) thickening agent and the solvent diethylene glycol monoethyl ether (DGME), which allows compositions to be prepared with increased solubilized concentrations of dapsone. A polymeric viscosity builder such as an A/SA, can minimize the yellowing of the composition and can reduce the particle size, and minimize a gritty feel upon application. The Almirral patent includes 62 generalized composition embodiments and eight specific example formulations.On inter partes review, the Patent Trial and Appeal Board agreed that claims 1–8 would have been obvious over prior art at the time the alleged invention was made. The Federal Circuit affirmed. The Board’s decision sets forth factual findings of similarity between carbomers and A/SA agents that support its conclusion that prior art discloses a range for each component of the composition that either fully encompasses or overlaps/abuts the ranges and amounts for those components recited in the challenged claims, sufficient to create a presumption of obviousness. The court upheld the Board’s analysis of whether a skilled artisan would have had a reasonable expectation of success in combining prior art teachings to achieve the claimed invention.

Cirrus petitioned for inter partes review of a patent that describes ballistic parachute systems that use a rocket to deploy a parachute, slowing the fall of a crashing aircraft. The Patent Trial and Appeal Board determined that the challenged claims are unpatentable as obvious over a combination of Cirrus Design’s Pilot Operation Handbook (POH) and the James patent. The POH describes the operation of a ballistic parachute system installed on the Cirrus SR22 airplane. The James patent, titled “Semiautonomous Flight Director,” describes a “device for programming industry-standard autopilots” to allow “for the safe operation of any aircraft by an unskilled pilot. The Board determined that proposed amended claims lacked written description.The Federal Circuit affirmed. The determination that the ordinarily skilled artisan would program James’s autonomous system to perform the claimed flight maneuvers suggested by POH is the result of a faithful application of precedent on obviousness, including a directive to consider the creativity of the ordinarily skilled artisan. That the prior art cautioned pilots not to use autopilot in some emergency situations on some aircraft does not mean that the skilled artisan would have been dissuaded from doing so in all emergency situations on all aircraft. Substantial evidence supports the finding of lack of written description. View "Fleming v. Cirrus Design Corp." on Justia Law

MPH’s challenged patents share a written description and purport to improve secure messaging between arbitrary hosts (e.g., messaging across local area networks (LANs), private and public wide area networks (WANs), or the internet) utilizing Internet Protocol (IP) security protocols. MPH asserted claims of the challenged patents against Apple, which petitioned for inter partes review of each claim of the three patents.The Board held that Apple failed to show that several dependent claims of each patent would have been obvious in view of a combination of prior art. The Federal Circuit affirmed. The court upheld the constructions of “intermediate computer configured to receive from a mobile computer a secure message sent to the first network address” as requiring the mobile computer to send the message to the first network address and of “information fields” as requiring “two or more fields.” Substantial evidence supported the Board’s finding with respect to motivation to modify the combination of prior art to use more than one field; Apple failed to show a motivation to modify the prior art combination to include substitution.
