Merck Sharp & Dohme LLC et al. v.The Johns Hopkins University
Merck Sharp & Dohme LLC successfully petitioned to institute IPR proceedings against The Johns Hopkins University regarding anti-cancer immunotherapy claims. The Board found sufficient evidence that the MSI-H Study Record anticipates key claims, warranting further trial on grounds of anticipation and obviousness.
Accelight Technologies, Inc. et al. v.Applied Optoelectronics, Inc.
The PTAB granted institution for IPR2025-01567 after finding the petitioner had a reasonable likelihood of prevailing. The notice also detailed multiple denials across various proceedings.
Apple Inc. v.Carbyne Biometrics, LLC
The PTAB found all challenged claims unpatentable by a preponderance of the evidence. Petitioner successfully argued obviousness over combinations of Stone, Hoyos, and Varghese across various claim sets. The Board agreed that an ordinary skilled artisan would have been motivated to combine these prior art references for fraud detection purposes.
Vicor Corporation v.Delta Electronics, Inc.
The PTAB institution decision for IPR2024-00705 found reasonable likelihood of success on claims 1-6, despite disputes over claim construction. The Petitioner argued that the combination of prior art references anticipated or rendered the patent obvious in the field of Power Converters/Circuit Boards.
Comcast Corporation et al. v.Entropic Communications LLC
Comcast Cable Communications successfully petitioned to institute IPR against Entropic Communications, LLC regarding claims in patent 8223775. The Board found sufficient evidence of obviousness over various prior art combinations, including Rabenko and Kim, particularly concerning modular hardware upgrades.
Accelight Technologies, Inc. et al. v.Applied Optoelectronics, Inc.
The USPTO granted institution for several IPR proceedings after petitioners demonstrated a reasonable likelihood of prevailing on their challenges against the patent. This moves these cases forward to the merits phase.
Caption Health, Inc. et al. v.University of British Columbia
The PTAB granted institution for IPR2025-01422, allowing Caption Health to proceed with challenging University of British Columbia's patent. The Board found a reasonable likelihood of prevailing on at least one claim.

The PTAB denied institution of the IPR for patent 12070691 (ImagineAR), finding that Niantic failed to meet the required likelihood standard.
Google LLC v.Secure Communication Technologies, LLC
The PTAB denied Google LLC's request to institute an IPR against Secure Communication Technologies, LLC regarding patent 11443344.
Teladoc Health, Inc. v.Data Health Partners, Inc.
Teladoc Health's IPR petition against Data Health Partners was denied by the PTAB, failing to establish a reasonable likelihood of prevailing on any claim. The Board adopted the Patent Owner's narrow construction of 'without input from the clients,' reinforcing its exclusion of client-initiated data when generating scores.
Amazon.com, Inc. et al. v.Nokia Technologies Oy
Amazon successfully navigated the institution phase of its IPR against Nokia regarding video coding claims. The Board found a reasonable likelihood that Amazon could prove unpatentability under § 103, leading to the case being instituted for trial.
Infineon Technologies Americas Corp. et al. v.MOSAID Technologies Inc.
The Director denied institution of an IPR against MOSAID's patent, ruling that Infineon failed to adequately explain conflicting claim construction positions taken in district court litigation.
Samsung Electronics Co., Ltd. et al. v.One-E-Way, Inc.
The PTAB issued multiple institution decisions, granting IPR for several cases including IPR2025-01516 after finding a reasonable likelihood of success. Other proceedings were denied based on discretionary or non-merits grounds.
Merck Sharp & Dohme LLC et al. v.The Johns Hopkins University
Merck Sharp & Dohme LLC successfully instituted an IPR against The Johns Hopkins University's patent, challenging claims related to anti-PD-1 antibodies for MSI-high cancer. The Board found sufficient evidence that prior art anticipated and rendered the claims obvious, leading to a trial institution decision.
Google LLC et al. v.EyesMatch Ltd.
Google LLC et al. successfully petitioned for institution of IPR against EyesMatch Ltd.'s patent 8982109, challenging claims based on obviousness (35 U.S.C. § 103). The Board declined to deny institution despite arguments regarding parallel district court litigation.
Samsung Electronics Co. Ltd. et al. v.Maxell, Ltd.
The PTAB found all challenged claims unpatentable as obvious (103), primarily based on the combination of Rogers and Rosenberg. The Board rejected the Patent Owner's attempt to narrow claim language regarding 'registering modes,' holding that they are input modes within a single operating mode.
Merck Sharp & Dohme LLC et al. v.The Johns Hopkins University
The PTAB found all 28 challenged claims unpatentable in this IPR proceeding concerning oncology/immunotherapy. The Petitioner successfully demonstrated that the MSI-H Study Record inherently anticipated or rendered obvious the claimed methods under both § 102 and § 103.
smaXtec Inc. et al. v.ST Reproductive Technologies, LLC et al.
The PTAB granted institution for the IPR challenge against a patent covering animal management systems using RFID technology. The Petitioner successfully argued that prior art references, including Trevarthen and Laitinen/Buchanan/Liao, provided sufficient motivation to combine elements of the challenged claims.
AMAZON.COM, INC. et al. v.Nokia Technologies Oy
The PTAB instituted the IPR, finding a reasonable likelihood of unpatentability for claims related to video compression and coding. The Board found that prior art references like Karczewicz and Frojdh, combined with H.263 standards, teach the claimed 'skip coding mode.'
Juniper Networks, Inc. v.Orckit Corporation
Juniper Networks' attempt to challenge Orckit's patent was denied by the PTAB. The Board cited General Plastic factors, finding that the claims were materially similar to those previously reviewed and Petitioner had prior knowledge of the asserted prior art.
Nokia of America Corporation et al. v.Iarnach Technologies Limited
Nokia of America Corporation et al.'s IPR petition against Iarnach Technologies Limited was denied by the PTAB, preventing trial on claims 1-11. The Board found that the combination of prior art references (G.984.3 and Khermosh) did not sufficiently teach or suggest the claimed method for managing upstream burst overhead parameters in PON systems.
Abbott Diabetes Care Inc. et al. v.DexCom, Inc.
Abbott Diabetes Care successfully petitioned to institute IPR proceedings against DexCom for patent infringement related to remote patient monitoring and glucose technology. The Board found a reasonable likelihood of prevailing on multiple grounds, specifically finding that prior art combinations rendered key claims obvious under 35 U.S.C. § 103.
Valve Corporation v.Immersion Corporation
Valve Corporation successfully convinced the PTAB to institute an IPR, challenging Immersion Corporation's patent claims related to haptic feedback systems. The Board found preliminary evidence suggesting that prior art references (Banerjee, Meglan, Rogers) anticipate or render obvious key elements of the asserted claims.
Luxottica of America Inc. et al. v.E-Vision Optics, LLC
The PTAB found all 19 challenged claims unpatentable based on obviousness (35 U.S.C. § 103). The Petitioner successfully demonstrated that combinations of prior art references, such as Howell-596 and Howell-158, rendered the claimed features in smart eyeglasses obvious to a Person Having Ordinary Skill in the Art (POSITA).
