Justia Patents Opinion Summaries

Incept’s 723 and 913 patents relate to improved methods for treating cancer, particularly prostate cancer, using radiation. The patents describe methods of introducing a filler between a radiation target tissue and other tissue to increase the distance between the two and thereby decrease the amount of radiation received by the non-targeted tissue. Palette sought inter partes review challenging the claims of the patents as unpatentable over prior art, including “Wallace,” describes a method for the “rapid formation of a biocompatible gel . . . at a selected site within a patient’s body.”The Federal Circuit affirmed the Patent Trial and Appeal Board in holding that the claims were anticipated or obvious, 35 U.S.C. 102, 103. Wallace discloses each element of claim 1 of the 723 patent, arranged as in that claim. The Board’s findings of motivation to combine are supported by substantial evidence in the form of the references themselves and Palette’s expert’s detailed testimony, which the Board found “persuasive.” With respect to Incept’s argument that the Board improperly dismissed the market share data that Incept provided, the court deferred to the Board’s findings concerning the credibility of expert witnesses.

Rembrandt’s 019 patent is directed to test assay devices and methods for testing biological fluids. The test assay device receives a fluid sample “introduced directly to the sample loading zone” of one or more assay test strips. Alere petitioned for inter partes review.The Patent Trial and Appeal Board found that claims 3–6 and 10 would have been unpatentable for obviousness. Rembrandt argues that the Board erred by relying on Alere’s new theories asserted for the first time in its reply brief. The Federal Circuit affirmed. Alere did not offer new theories. Alere’s reply argument was responsive to Rembrandt’s arguments and the Board’s observations. Substantial evidence supports the Board’s determinations. The Board was presented with “two alternative theories” about what the prior art discloses; the court reasoned that it was not its task “to determine which theory we find more compelling.” View "Rembrandt Diagnostics, LP v. Alere, Inc." on Justia Law

This action represents Metabyte’s fourth attempt to hold Technicolor liable for Technicolor’s allegedly improper auction of a patent portfolio in 2009. After the French courts ruled they lacked jurisdiction in the criminal action, Metabyte brought an action in district court alleging a federal RICO claim and several state law causes of action. After the district court ruled that equitable tolling did not apply to its RICO claim as a matter of federal law, Metabyte dismissed the federal action and brought its state law claims in Los Angeles County Superior Court. The trial court granted Technicolor’s demurrer without leave to amend. Metabyte contends the trial court erred in finding equitable estoppel applies only where a plaintiff invokes remedies designed to lessen the extent of a plaintiff’s injuries or damages, with the result that Article 145 proceeding in France could not support equitable tolling because it did not provide such a remedy. Technicolor defends the trial court’s ruling but devotes more of its energies to its contentions that even if equitable tolling did apply, the order should be affirmed by applying the doctrines of issue preclusion and judicial estoppel.   The Second Appellate District affirmed the trial court’s ruling sustaining the demurrer on the alternate ground that Metabyte failed to adequately plead facts showing that its decision to proceed in France was objectively reasonable and subjectively in good faith. However, the court granted Metabyte leave to amend. Accordingly, the court reversed the judgment and remanded for further proceedings. View "Metabyte v. Technicolor S.A." on Justia Law

Medtronics’s patents, which share a specification, relate to the transcutaneous (through the skin) charging of implanted medical devices. This charging occurs by inductive coupling, whereby energy is transferred between a primary coil in the external charger and a secondary coil in the implanted device when the two coils are placed in proximity to each other. The patents seek to improve charging efficiency by automatically varying the power output of the external charger based on various measured parameters of the current passing through the implanted device.In two inter partes review (IPR) determinations. The Patent Trial and Appeal Board held that the petitioner had failed to show that claims of the patents were unpatentable as anticipated or obvious. In each decision, the Board adopted a "two-input" claim construction first presented in the patent owner’s response after the institution decision and declined to consider the petitioner’s reply arguments and evidence under the new claim construction, reasoning that the petitioner had not identified anywhere in the petition that the two-input anticipation arguments had been made.The Federal Circuit vacated. The Board’s refusal to consider the new arguments and evidence was erroneous. The court remanded for the Board to consider the merits of Axonics’ responsive arguments and evidence under the new claim construction. View "Axonics, Inc. v. Medtronic, Inc." on Justia Law

Plaintiff alleged that Valeant fraudulently obtained two sets of patents related to a drug and asserted these patents to stifle competition from generic drugmakers. Plaintiff further alleged that Defendants defrauded the federal government by charging an artificially inflated price for the drug while falsely certifying that its price was fair and reasonable. Dismissing Plaintiff’s action under the False Claims Act’s public disclosure bar, the district court concluded that his allegations had already been publicly disclosed, including in inter partes patent review (“IPR”) before the Patent and Trademark Office.   The Ninth Circuit reversed the district court’s dismissal. The panel held that an IPR proceeding in which the Patent and Trademark Office invalidated Valeant’s “‘688” patent was not a channel (i) disclosure because the government was not a party to that proceeding, and it was not a channel (ii) disclosure because its primary function was not investigative. The panel held that, under United States ex rel. Silbersher v. Allergan, 46 F.4th 991 (9th Cir. 2022), the patent prosecution histories of Valeant’s patents were qualifying public disclosures under channel (ii). The panel assumed without deciding that a Law360 article and two published medical studies were channel (iii) disclosures. The panel held that the “substantially the same” prong of the public disclosure bar applies when the publicly disclosed facts are substantially similar to the relator’s allegations or transactions. None of the qualifying public disclosures made a direct claim that Valeant committed fraud, nor did they disclose a combination of facts sufficient to permit a reasonable inference of fraud.

United Therapeutics holds New Drug Application (NDA) 022387 for Tyvaso®, an inhaled solution formulation of treprostinil approved for the treatment of pulmonary hypertension. It is a vasodilator that reduces vasoconstriction in the pulmonary vasculature, thereby decreasing blood pressure. United’s patents are listed in the FDA’s Orange Book for Tyvaso. Liquidia filed NDA 213005 for Yutrepia™ (21 U.S.C. 355(b)(2)), a dry powder inhalation formulation of treprostinil that is not a generic version of any currently marketed drug. United sued Liquidia, alleging infringement. Liquidia filed a petition for inter partes review (IPR); the Board found all claims of the 793 patent unpatentable as obvious. The district court concluded that seven claims of the 793 patent were not invalid and were infringed by Liquidia; several claims of the 066 patent were invalid as anticipated and would have been infringed by Liquidia but for the finding of anticipation; and claim 8 of the 066 patent was not invalid and not infringed.The Federal Circuit affirmed, upholding the district court’s determination that the meaning of “treating pulmonary hypertension” does not require a showing of safety and efficacy; the claims of the 793 patent are adequately enabled and supported by the written description; and Liquida induced infringement of that patent.

Trinity sued Covalent for infringement of patent claims relating to methods and systems for connecting users based on their answers to polling questions. The Federal Circuit affirmed the dismissal of the suit, concluding that the asserted patents do not claim patentable subject matter under 35 U.S.C. 101. Because Trinity did not identify a proposed claim construction or specific facts to be discovered, the district court was not required to conduct claim construction and fact discovery before analyzing the asserted claims. The claims are directed to the abstract idea of matching based on questioning. A human mind could review people’s answers to questions and identify matches based on those answers; the patent’s requirements that the abstract idea be performed on a “hand-held device” or that matches are “reviewable by swiping” does not alter the conclusion that the focus of the asserted claims remains directed to an abstract idea, not an improvement on technology. The claims do not provide an inventive concept by virtue of their use of multiple processors, match servers, unique identifications, or a match aggregator. View "Trinity Info Media, LLC v. Covalent, Inc." on Justia Law

SNIPR's patents, directed to methods of selectively killing bacteria using CRISPR gene editing, claim priority to a 2016 Patent Cooperation Treaty (PCT) Application. Because their effective filing dates are after March 2013, they are pure America Invents Act (AIA) patents, examined and issued under first-inventor-to-file patentability requirements. The Rockefeller Application is also directed to selectively killing bacteria. It claims priority to a 2014 PCT Application and a February 2013 U.S. Provisional Application; it is a pure pre-AIA application.The Patent Board declared an interference to determine which party was the first to invent, then identified Rockefeller as the senior party, with an accorded benefit date of February 2013, and SNIPR as the junior party, with a May 2016 accorded benefit date (the date for which the Board recognizes that a patent application provides a proper constructive reduction to practice of the invention under pre-AIA 35 U.S.C. 102(g)(1)). SNIPR unsuccessfully moved to terminate, arguing that the AIA eliminated interferences for AIA patents. The Board reasoned that pre-AIA patent claims must “comply with [pre-AIA] 35 U.S.C. 102(g),” which requires an interference. SNIPR had not filed any priority statement asserting an invention date earlier than Rockefeller’s earliest accorded benefit date and failed to overcome Rockefeller’s senior party status. The Board canceled the SNIPR Patents.The Federal Circuit reversed. Pure AIA patents may not be part of an interference. SNIPR’s pure AIA patents were examined and issued under the AIA’s first-inventor-to-file patentability requirements and cannot be canceled under the pre-AIA invention priority requirements.

Float‘N’Grill's patent is directed to a float designed to support a grill to facilitate a user grilling food while remaining in a body of water. The specification describes a single embodiment. The apparatus includes a float and a pair of grill supports, each of which has a base rod, and an “inverted substantially U-shaped upper support medially attached to a top surface of the base rod.” Each of the supports “includes a plurality of magnets disposed within the middle segment of the upper support of each” grill support. After the patent was issued, FNG, believing that it claimed less than it was entitled to claim in the original patent, filed a reissue application, seeking claims that did not contain the narrow “plurality of magnets” limitation; the claims more generically call for the removable securing of a grill to the float apparatus.The Patent Trial and Appeal Board affirmed an Examiner’s rejections under 35 U.S.C. 112(b) and 251 of the 13 claims of the reissue application. The Federal Circuit affirmed. The reissue claims in question do not cover “the invention disclosed in the original patent” as required by 35 U.S.C. 251. The court did not address the indefiniteness of those claims under section 112(b). View "In Re Float‘N’Grill LLC" on Justia Law

The Medtronic patents describe and claim a neurostimulation lead and a method for implanting and anchoring the lead. Axonics, having been sued by Medtronic for infringement, challenged various claims of the Medtronic patents for obviousness in inter partes reviews (IPRs) under 35 U.S.C. 311–319. In both IPRs, the Patent Trial and Appeal Board concluded that Axonics had failed to prove any of the challenged claims unpatentable.The Federal Circuit vacated and remanded, The Board erred in its obviousness analysis and the errors cannot be regarded as harmless. Even if the Board was correct to treat the Medtronic patents as limited in the problem they address to the sacral-nerve context, it committed a fundamental legal error in confining the motivation inquiry to whether a motivation would exist to make the proposed combination for use in the specific trigeminal-nerve context—to which the Medtronic patents are not limited. The Board was also incorrect in its view that “the relevant art is medical leads specifically for sacral neuromodulation,” as the Medtronic patents’ claims are not limited to the sacral-nerve context; the shared specification, properly read, is not so limited either.
