Justia Patents Opinion Summaries

The DivX patent explains, in a section titled “Background of the Invention,” that “[t]he present invention relates generally to encoding, transmission and decoding of multimedia files.” In its petition for inter partes review, Netflix asserted that several claims of the patent would have been obvious in view of prior art, Zetts as modified by Kaku. In a section titled “Field of the Invention,” Kaku’s specification states that the invention “relates to motion image apparatuses and, more particularly, to a motion image reproducing apparatus which is applicable to a digital camera for reproducing motion image data recorded on a recording medium.” The Patent Trial and Appeal Board found that Kaku failed to qualify as analogous art.The Federal Circuit vacated and remanded. The Board failed to identify the field of endeavor for either the challenged patent or the prior art and thus failed to establish analogous art under the field of endeavor test. The Board’s directive that Netflix more precisely articulate the relevant field of endeavor to meet its burden was unduly strict. View "Netflix, Inc. v. DivX, LLC" on Justia Law

The Corephotonics patent is directed to creating “portrait photos” and discloses “a thin (e.g., fitting in a cell phone) dual-aperture zoom digital camera” that combines images taken by a wide lens and a tele lens to create a fused still image. Apple filed petitions for inter partes review, each challenging various claims of the patent as obvious in view of multiple prior art references. The Patent Trial and Appeal Board rejected Apple’s arguments.The Federal Circuit vacated and remanded. Neither the claim language nor the specification presents a cut-and-dry case of claim construction for “fused image with a point of view of the Wide camera” but taken together and in context, the intrinsic evidence supports that the claim term requires only that the fused image maintain Wide perspective point of view or Wide position point of view, but does not require both. Apple’s proposed construction is more in line with the intrinsic evidence. In addition, the Board based its second decision on a ground not raised by any party in violation of the Administrative Procedure Act. View "Apple, Inc. v. Corephotonics Ltd." on Justia Law

Sisvel’s 698 and 196 patents claim methods and apparatuses that rely on the exchange of frequency information in connection with cell reselection between a mobile station (or user cell phone) and a central mobile switching center. Both are entitled “Cell Reselection Signalling Method.” The 196 patent is a continuation of the application that eventually gave rise to the 698 patent.The Patent Trial and Appeal Board concluded that multiple claims in each patent are unpatentable as anticipated and/or obvious in view of certain prior art. Sisvel challenged the Board’s construction of a single claim term, “connection rejection message” and the Board’s denial of its revised motion to amend the claims of the 698 patent. The Federal Circuit affirmed, agreeing that “connection rejection message” should be given its plain and ordinary meaning of “a message that rejects a connection.” The Board correctly determined that Sisvel failed to meet its burden to show that the scope of its substitute claims is not broader than the scope of its original claims.

Cellect’s challenged patents are directed to personal digital-assistant devices or phones. Each claims priority from a single application, the 255 patent. The 369 and 626 patents are continuations-in-part of the 255 patent. The 742 patent is a continuation-in-part of the 369 patent; the 621 patent is a continuation-in-part of the 626 patent. The 036 patent is a continuation of the 626 patent. Each of the challenged patents was granted Patent Term Adjustment (PTA) for Patent Office delay during prosecution (pre-AIA 35 U.S.C. 154(b)); each would have expired on the same day but for the grants of PTA. None were subject to a terminal disclaimer during prosecution; the patents have all expired.Cellect sued Samsung for infringement. Samsung requested ex parte reexaminations, asserting that the patents were unpatentable based on obviousness-type double patenting (ODP). The examiner determined that the challenged claims were obvious variants of Cellect’s prior-expiring reference patent claims, tracing back to the 036 patent, which did not receive PTA and retained an expiration date 20 years after the filing of the 255 application. The 621 patent claims were unpatentable over the 626 patent claims, which were unpatentable over the 369 patent claims. The 742 patent claims were unpatentable over the 369 claims. The 369 patent claims were unpatentable over the 036 claims, which did not receive PTA. The Board and Federal Circuit affirmed. ODP for a patent that has received PTA, regardless of whether a terminal disclaimer is required or has been filed, must be based on the expiration date of the patent after PTA has been added.

Volvo’s 692 patent is directed to a tractor-type stern drive for a boat. A stern drive is an engine mounted in the boat's hull, connected to a drive unit mounted outside of the hull, typically on the stern; it is also called an “inboard/outboard drive.” A tractor-type drive generally relies on forward, bow-facing propellers that pull the boat through the water. In 2015, Volvo launched its commercial embodiment of the patent, the Forward Drive, which became extremely successful for water sports, including wake-surfing. The forward-facing propellers increased the distance between the propeller and swimmers, compared with prior, pulling-type stern-drive boats. In 2020, Brunswick launched its own drive that embodies the 692 patent, the Bravo Four, and petitioned for inter partes review, asserting that all claims would have been anticipated or obvious based on several references.The Patent Trial and Appeal Board found all claims unpatentable as obvious. The Federal Circuit vacated. The Board’s finding of a motivation to combine was supported by substantial evidence but the Board failed to properly consider the evidence of objective indicia of nonobviousness. Volvo established a nexus between its objective evidence of secondary considerations and the claimed invention. Even if its assignment of weight to each factor was supported by substantial evidence (“some weight” for copying, industry praise, and commercial success; and “very little weight” for skepticism, failure of others, and long-felt unsolved need), the Board did not discuss the summation of the factors.

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

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

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
