BOE TECHNOLOGY GROUP CO., LTD. v.Bishop Display Tech LLC
BOE Technology Group has filed an IPR petition challenging Bishop Display Tech’s LED driver patent (U.S. 8,093,830). The petition asserts that prior art references Ghanem, Nishimura, and Tripathi render all five claims obvious under §103. The Board is asked to institute the review and find the claims unpatentable.
Apple Inc. v.ImberaTek, LLC
Apple and ImberaTek have jointly filed a motion to terminate the IPR covering patent 9,107,324, citing a settlement agreement and good cause under PTAB precedent. The motion seeks to end the pre‑institution proceeding to conserve resources.
BOE Technology Group Co., Ltd. v.Optronic Sciences LLC
BOE Technology Group petitions the PTAB to invalidate eight claims of Optronic Sciences’ 8,604,471 OLED display patent, arguing obviousness over Hwang and combinations with Godo and Yamashita. The petition also argues that discretionary denial is not warranted.
Amphenol Corporation v.Credo Technology Group Ltd.
Amphenol and Credo Technology settled four inter partes review proceedings, leading the PTAB to terminate the cases before trial.
Google LLC et al. v.Mullen Industries LLC
The Director denied requests for review in multiple IPR proceedings involving Google and Mullen Industries regarding patent 11234117. This decision maintains the prior institution decisions across several related cases.
BOE Technology Group Co., LTD v.Optronic Sciences LLC
The Board found all seven challenged claims unpatentable, rejecting the patent owner's narrow construction of 'passivation layer.' The petitioner successfully demonstrated that combining prior art references (Anzai and Yamazaki) taught or rendered obvious the claimed invention in OLED devices.
MediaTek Inc. et al. v.ParkerVision, Inc.
MediaTek Inc. successfully petitioned to challenge ParkerVision, Inc.'s '593 patent in an IPR proceeding before the PTAB. The Board instituted the trial on all 20 challenged claims based on obviousness (103), despite arguments regarding constitutional due process and duplication of district court litigation.
Aptiv Services US, LLC et al. v.Microchip Technology, Inc.
Aptiv Services challenged Microchip Technology's LDO voltage regulator patent (9471074), arguing that the claimed features are obvious over prior art. The petitioner relies heavily on combinations of references like Al-Shyoukh, Rincon-Mora, Ivanov, and Stanescu to demonstrate lack of inventive step.
Reed Semiconductor Corporation v.Monolithic Power Systems, Inc.
Reed Semiconductor Corporation has filed a petition challenging 16 claims of Monolithic Power Systems' '377 Patent, asserting that the patent is anticipated or rendered obvious by prior art from Tateishi. The challenge leverages the buck-converter circuit disclosed in Tateishi to invalidate key features of the step-down regulator.
Samsung Display Co., Ltd. et al. v.Pictiva Displays International Ltd. et al.
Samsung Display Co., Ltd. successfully petitioned the PTAB against Pictiva Displays International Ltd.'s OLED patents, leading to an Institution Decision on all claims. The dispute centers on whether specific materials qualify as 'matrix material' in Organic Light-Emitting Diodes (OLEDs).
Innoscience America, Inc. et al. v.Infineon Technologies Austria AG
Innoscience America challenges Infineon's patent on power semiconductor packaging, asserting obviousness under 35 U.S.C. § 103. The petitioner argues that combining known device structures with established packaging techniques renders the claimed features predictable to a Person Having Ordinary Skill in the Art.
IKEA Supply AG et al. v.Everlight Electronics Co., Ltd.
IKEA Supply and Everlight Electronics settled their dispute over U.S. Patent 9,905,742, leading the PTAB to terminate the inter partes review after it had been instituted. The settlement agreement is to be kept confidential per regulatory provisions.
TCL Electronics Holdings Ltd. (f/k/a TCL Multimedia Technology Holdings, Ltd.) v.Maxell, Ltd.
The Director vacated the institution decision in a dispute involving TCL and Maxell, denying the IPR based on an error in weighing discretionary factors. The denial relates to patent 10375341.
Vicor Corporation v.Delta Electronics, Inc.
The PTAB denied institution of Vicor Corporation's IPR against Delta Electronics, Inc., finding Petitioner failed to demonstrate a reasonable likelihood of prevailing. The denial hinged on the argument that Petitioner relied on impermissible hindsight bias when combining prior art references for obviousness and anticipation grounds.
Nichia Corporation v.BX LED LLC
Nichia and LED maker BX LED have settled their dispute over U.S. Patent 7,973,465 and jointly moved to terminate the pending IPR. The motion cites lack of institution and no merits decided, requesting Board approval of termination.
Microchip Technology, Inc. v.Aptiv Technologies AG et al.
Aptiv has filed objections to more than 40 exhibits submitted by Microchip in IPR2024‑00495, arguing they are irrelevant, lack foundation, or contain hearsay. The objections cite Federal Rules of Evidence and seek to exclude the material from the trial that has already been instituted.
Arm Ltd. v.ICPillar LLC
Arm Ltd.'s IPR challenge against ICPillar LLC's '8924899 patent was instituted by the PTAB, focusing on obviousness over prior art including Rompaey and Banerjee. The Board adopted a broad claim construction for key software commands, allowing the case to proceed to trial.
