In Lynk Labs v. Samsung Electronics, the Federal Circuit determined that “a published patent application can be deemed prior art in an IPR as of the application’s filing date.” The Court affirmed the PTAB’s determination that challenged claims of U.S. Patent No. 10,687,400 (the ’400 patent), which relates to light emitting diodes (LEDs), are
In a decision that underscores the importance of prior art in the context of AI patents, the PTAB recently issued a final decision in Tesla, Inc. v. Autonomous Devices, LLC, IPR2023-01173 (PTAB January 3, 2025), invalidating all challenged claims of U.S. Patent Number 11,055,583 (the “’583 patent”). The case provides some insight into how
In ParkerVision, Inc. v. Qualcomm Inc., No. 2022-1755, -2221 (Fed. Cir. Sept. 6, 2024) (“ParkerVision III”), the Federal Circuit held that, due to the difference in burdens of proof in PTAB IPR proceedings and in district court cases, collateral estoppel cannot be applied in a district court case based on findings made
In Voice Tech Corp v. Unified Patents, LLC, the Federal Circuit affirmed the PTAB’s IPR decision that the challenged claims of Voice Tech’s patent were unpatentable for obviousness, determining that the PTAB’s findings were supported by substantial evidence. At issue were claims 1-8 of U.S. Patent No. 10,491, 679, which relates to use of
In Virtek Vision Int’l. ULC v. Assembly Guidance Systems, Inc. the Federal Circuit reversed in part the PTAB’s final written decision in an IPR petition filed by Assembly Guidance, on the basis that the petition failed to identify a motivation to combine elements present in the prior art, stating that: “A reason for combining must exist.” Virtek Vision Int’l ULC v. Assembly Guidance Sys., Inc., 97 F.4th 882, 888 (Fed. Cir. 2024). The Court determined that Assembly Guidance had failed to provide any reasoning why one skilled in the art would be motivated to combine the disclosures of the prior art references, and therefore did not show that the challenged claims were unpatentable.Continue Reading Give Me ONE Reason: Federal Circuit Requires At Least One Reason for Motivation to Combine
As discussed in a recent post, On May 21, 2024, the Federal Circuit issued its en banc decision in LKQ Corp. v. GM Global Tech. Operations LLC, significantly impacting design patent law. The court overturned the long-standing Rosen–Durling test, a two-part test used to assess the obviousness of design patents. This decision is expected to have far-reaching implications for patent practitioners and clients alike.Continue Reading Federal Circuit Abandons Rosen-Durling Test for Design Patent Obviousness
Can a defendant who prevails in an exceptional patent infringement suit by invalidating the patent in inter partes review (IPR) recover its associated Patent Office-related attorney’s fees? A split three-judge panel of the Federal Circuit recently said no in Dragon Intellectual Property LLC v. Dish Networks LLC, Appeal Nos. 2022-1621, -1777, Slip Op. at 8 (Fed. Cir. May 20, 2024) (“Dragon V”). This blogsite previously discussed (link) several instances where courts, including the Federal Circuit, have authorized this recovery when the Patent Office proceedings substituted for aspects of the district court litigation between the same parties. How then did this two-judge majority conclude otherwise?Continue Reading Federal Circuit Holds Recoverability of Attorney’s Fees Does Not Extend to AIA Trials
On June 30th, the Federal Circuit granted a petition for re-hearing en banc in LKQ Corp. v. GM Global Tech. Operations LLC.[1] LKQ, an auto parts repair vendor for GM, successfully petitioned for inter partes review of GM’s design patent for a front fender design,[2] arguing it was anticipated by a prior art reference (Lain) and obvious over Lian alone or in combination with a brochure for the 2010 Hyundai Tucson. The PTAB ultimately affirmed the patentability of GM’s claimed design, prompting LKQ to appeal to the Federal Circuit. On appeal, LKQ argued that the PTAB’s obviousness analysis utilized tests overruled by the Supreme Court’s decision in KSR, and, as such, the obviousness standard for design patents should mirror the standard for utility patents set forth in KSR. However, a three-judge panel of the Federal Circuit disagreed, noting in relevant part that “it is not clear the Supreme Court has overruled” the tests for obviousness applied by the PTAB.Continue Reading Federal Circuit to Decide Whether KSR Applies to Design Patents
Can a petitioner’s reply in an IPR proceeding present new arguments and evidence responding to a proposed claim construction first raised in the patent owner’s response? In Axonics, Inc. v. Medtronic, Inc., Nos. 2022-1532, 2022-1533 (Fed. Cir. Aug. 7, 2023), the Federal Circuit answered in the affirmative, vacating the PTAB’s final written decision of
After the Supreme Court’s decision in United States v. Arthrex, Inc., the Patent Office implemented an interim process for the Director to review Patent Trial and Appeal Board decisions in AIA trials. The Office sought public feedback on the process last year (link) and received more than 4,000 responses (link)! The process has yet to be formalized via traditional notice and comment rulemaking, though someday, perhaps, it will. Until then, the Patent Office continues to offer new updates and information, most recently on July 24, 2023.Continue Reading PTAB Updates and Expands the Director Review Process and Offers Transparency in Ex Parte Appeals
