Justia Patents Opinion Summaries

The application for the 208 patent was filed in 2012 and claims a priority date of November 7, 2011. It is directed to surgical devices for an “endometrial ablation,” which stops or reduces abnormal uterine bleeding. The procedure generally involves inserting a device having an energy-delivery surface into a patient’s uterus, expanding the surface, energizing the surface to “ablate” or destroy the endometrial lining of the patient’s uterus, and removing the surface.Minerva sued Hologic for infringement. After discovery, the district court granted summary judgment that the asserted claims are anticipated under the public use bar of pre-AIA 35 U.S.C. 102(b). The Federal Circuit affirmed. The patented technology was “in public use” because, before the critical date, for several days, Minerva disclosed 15 devices having the technology at the industry’s “Super Bowl,” Minerva showcased them at a booth, in meetings with interested parties, and in a technical presentation. Minerva did not disclose the devices under any confidentiality obligations, despite the commercial nature of the event. At the time of that public use, the technology was “ready for patenting.” Minerva had created working prototypes and technical documents describing the claimed technology. There are no genuine factual disputes. View "Minerva Surgical, Inc. v. Hologic, Inc." on Justia Law

SSI alleged that DZEM infringes two of SSI’s patents that are generally directed to sensors for determining the characteristics of fluid in a container, such as a fuel tank. SSI’s commercial embodiments of the asserted patents and DZEM’s accused products are systems that determine the quality and volume of diesel exhaust fluid that is used in emission-reduction systems for diesel truck engines. DZEM asserted counterclaims for invalidity of the asserted patents and for tortious interference with prospective business relations.The district court granted DZEM summary judgment on the infringement claims and dismissed DZEM’s invalidity counterclaims, granting SSI summary judgment on the tortious interference counterclaim. The Federal Circuit vacated in part, reversing the district court’s construction of the term “filter” as used in the 038 patent. The term is properly construed to mean “a device containing openings through which liquid is passed that blocks and separates out matter, such as air bubbles.” On remand, SSI will not be precluded from arguing that DZEM’s accused sensors infringe under the doctrine of equivalents. The court affirmed summary judgment with respect to the 153 patent and DZEM’s counterclaim for tortious interference. View "SSI Technologies, LLC, v.

ChromaDex’s 807 patent is directed to dietary supplements containing isolated nicotinamide riboside (NR), a form of vitamin B3 naturally present—in non-isolated form—in cow’s milk and other products. Animal cells convert ingested NR into the coenzyme nicotinamide adenine dinucleotide, or NAD+. NAD+ deficiencies can cause diseases in both animals and humans. ChromaDex sued Elysium, a former ChromaDex customer, for patent infringement.The district court construed several claim terms, finding “isolated [NR]” to mean “[NR] that is separated or substantially free from at least some other components associated with the source of [NR].” The district court granted Elysium summary judgment, finding that the asserted claims were invalid under 35 U.S.C. 101. The Federal Circuit affirmed. The asserted claims concern a product of nature and are not patent eligible. They do not have characteristics markedly different from milk; both “increase[] NAD+ biosynthesis upon oral administration.” Recognizing the utility of NR is nothing more than recognizing a natural phenomenon, which is not inventive. The act of isolating the NR by itself, “no matter how difficult or brilliant it may have been” does not turn an otherwise patent-ineligible product of nature into a patentable invention.

Google filed two petitions for inter partes review (IPR) challenging CyWee’s patents. On December 11, 2018, the Patent Trial and Appeal Board instituted IPR on all challenged claims. Each IPR was joined by other parties, so the Board extended its one-year deadline for the final written decisions by one month, to January 10, 2020. On January 9, 2020, the Board issued its final decisions, finding all challenged claims unpatentable for obviousness. CyWee challenged the merits of the unpatentability determinations and the appointment of Board administrative patent judges (APJs) as unconstitutional under the Appointments Clause, In March 2021 the Federal Circuit affirmed, rejecting the Appointment Clause challenge as foreclosed by then-governing precedent, including its “Arthrex” decision.The Supreme Court subsequently held, in Arthrex, that APJs’ power to render final patentability decisions unreviewable by an accountable principal officer was an Appointments Clause violation. The Court remedied the violation by vitiating anything in 35 U.S.C. 6(c) that prevented the Director from reviewing final Board IPR decisions and “remand[ing] to the Acting Director” for a decision on whether to rehear the case. The Federal Circuit then remanded to allow CyWee to request a rehearing. The Commissioner denied rehearing. CyWee filed amended notices of appeal challenging the rehearing denials and the Commissioner’s authority to perform the review Arthrex contemplates. The Federal Circuit affirmed, rejecting arguments that the one-month extension rendered the decisions untimely. The Supreme Court’s Arthrex decision compelled rejection of its other arguments.

Jawbone sued Google for patent infringement in the Western District of Texas after being assigned ownership of the nine asserted patents and seven months after being incorporated in Texas. Jawbone rents space in Waco to store documents relating to the patents, from which it conducts some distribution and sales activities. No Jawbone personnel work at any location in the Western District. Google moved under 28 U.S.C. 1404(a) to transfer the action to the Northern District of California, arguing that: the relevant technical aspects of the accused earbuds, smartphones, speakers, displays, and software products were researched, designed, and developed at Google’s headquarters within Northern California; the technology underlying the asserted patents assigned to Jawbone was likewise developed and prosecuted in Northern California; witnesses and sources of proof (prototypes, Google’s key personnel, and four of the six named inventors) were primarily located in Northern California; no witnesses or sources of proof were located in Western Texas.The Federal Circuit ordered the district court to grant the motion. The center of gravity of this action, focusing on the “Volkswagen factors” and the overriding convenience inquiry, is clearly in the Northern District of California, not in the Western District of Texas. Four factors favor transfer and four factors are neutral. No factor weighs against transfer. View "In Re Google LLC" on Justia Law

In 2015, PMC sued Apple, alleging that Apple FairPlay, a digital rights management technology that Apple uses on its computers, mobile phones, and other devices to prevent users from unauthorized uses of content—such as illegally copying songs on iTunes–alleging infringement of its 091 patent. A jury found that Apple infringed at least one of claims and awarded PMC over $308 million in reasonable-royalty damages.The district court held a bench trial on remaining issues and found the 091 patent unenforceable based on prosecution laches. The court determined that laches required a challenger to prove that the applicant’s delay was unreasonable and inexcusable under the totality of the circumstances and that there was prejudice attributable to the delay. The Federal Circuit affirmed, agreeing that PMC engaged in an unreasonable and unexplained delay amounting to an egregious abuse of the statutory patent system. There was no clear error in the district court’s determination that PMC engaged in conduct causing delays at least through 2011. Apple began developing FairPlay in the early 2000s and launched it in 2003, so Apple necessarily invested in or worked on FairPlay before 2003, which is undisputedly during the period of delay.

Grace sued Chandler alleging infringement of its 877 patent, which concerns measuring the viscosity of the fluid in oil wells. The patent’s design is intended to eliminate measurement error because of sample mixing with pressurization fluid in a comparative viscometer. The district court construed the term “enlarged chamber” as indefinite and the term “means for driving said rotor to rotate located in at least one bottom section.” The parties then stipulated that 11 asserted claims were invalid and that certain claims were not infringed.The Federal Circuit vacated the district court’s determination that the term “enlarged chamber” is indefinite and remanded. Although “enlarged chamber” is not a term of art, the intrinsic record sufficiently guides a skilled artisan to the meaning of that term as used in the patent as “a chamber that is large enough to contain excess test sample prior to pressurization to prevent mixing of the test sample and pressurization fluid in the lower measurement zone when the test sample is pressurized to maximum rated pressure.” The court affirmed the construction of “means for driving said rotor to rotate located in at least one bottom section.” View "Grace Instrument Industries, LLC v. Chandler Instruments Co.," on Justia Law

Stingray filed patent infringement suits in the Eastern District of Texas against TP-Link (organized and headquartered in China). TP-Link moved to dismiss for lack of personal jurisdiction or, alternatively, to transfer to the Central District of California (CDCA) under 28 U.S.C. 1406. TP-Link argued it was not subject to personal jurisdiction i Texas and that Federal Rule of Civil Procedure 4(k)(2) “does not cure this jurisdictional defect because Defendants would be amenable to suit in the Central District of California.” TP-Link also moved for transfer under 28 U.S.C. 1404(a). The court transferred the cases to the CDCA under section 1406, stating that its exercise of personal jurisdiction "would be unreasonable” and, “Defendants are amenable to suit in the CDCA” and have made affirmative representations that CDCA has proper jurisdiction and venue.The Federal Circuit granted a mandamus petition. TPLink’s unilateral, post-suit consent to personal jurisdiction in another state did not defeat the application of Rule 4(k)(2), which closed a pre-1993 loophole by which a nonresident defendant who did not have minimum contacts with any individual state sufficient to support the exercise of jurisdiction but did have sufficient contacts with the United States as a whole, could escape jurisdiction every state. The district court may assess whether TP-Link can satisfy Rule 4(k)(2)’s negation requirement on the grounds that Stingray “could have brought suit” in the CDCA, independent of TP-Link’s post-suit consent or may consider transfer under section 1404(a).

Google’s 093 patent application discloses methods for filtering the results of an internet search query such that only results appropriate for the user (e.g., age-appropriate) are displayed.. According to the disclosed method, each result of a search query is assigned a “content rating class” indicating the suitability of the associated content (e.g., suitable for all ages). The Patent Trial and Appeal Board affirmed an examiner’s rejection of multiple claims of the application, citing 35 U.S.C. 103.The Federal Circuit vacated and remanded for further proceedings. The court rejected arguments that the claims were obvious in light of prior art because those arguments did not reflect the reasoning or findings the Board actually invoked. Although the Board concluded that modifying prior art to take into account query length would have been obvious, there was no discussion of how such a modification would be accomplished. The Board’s expressed reasoning cannot sustain its rejection of the claims. The prior art arguments rest on factual predicates unaddressed by the examiner or Board.

The parties copied one another’s claims and provoked an interference between Agilent’s and Dionex's patent applications. The Patent Trial and Appeal Board identified Dionex as the senior party, requiring that Agilent prove priority by a preponderance of the evidence. The Board defined a single count as claim 1 of Agilent’s patent application concerning a method of operating a liquid chromatography system. Dionex argued that Agilent’s claims were invalid based on a lack of written description support for the limitation: “determining a movement amount of the piston within the chamber from a first position to a second position to increase a pressure in the sample loop from an essentially atmospheric pressure to the pump pressure, based on the pump pressure.” The Board concluded that Agilent’s specification controlled, construed the disputed language in light of that specification, and found that the specification provided adequate written description support.The Board found that Agilent proved conception as of May 2007, and actual reduction to practice as of June 1, 2007, all before Dionex’s earliest alleged conception date in December 2007, crediting the testimony of one of Agilent’s two co-inventors, corroborated by two co-workers. The Board also denied Dionex’s requests to draw negative inferences from the lack of testimony from the other co-inventor, and the lack of contemporaneous documentary evidence. The Federal Circuit affirmed. View "Dionex Softron GmbH v. Agilent Technologies, Inc." on Justia Law
