In IPR2024‑01094, the PTAB held claims 1,2,6,8‑14 of Pictiva’s OLED patent unpatentable over the Ma reference, while claims 3‑4 were upheld. The decision hinged on obviousness of joint vaporization and metal‑complex coordination.
AdvanCell Pty Ltd. v.Sciencons AS et al.
AdvanCell Pty Ltd.'s PGR against Sciencons AS et al. was instituted by the PTAB, finding sufficient evidence that several claims are unpatentable. The Board adopted Petitioner's interpretation of a key time-based limitation in Claim 20 during the institution phase.
WHOOP, Inc. v.Omni MedSci, Inc.
The PTAB held that WHOOP proved unpatentability of 12 of the 23 claims of Omni MedSci’s wearable physiological‑measurement patent, while the remaining 11 claims were left intact. The decision hinged on obviousness over a combination of prior‑art references covering optical sensing, modulation, and AI‑driven analysis.
WHOOP, Inc. v.Omni MedSci, Inc.
The PTAB held that WHOOP’s challenge succeeded, finding all of the asserted claims of Omni MedSci’s ‘533 patent unpatentable as obvious over Lisogurski, Carlson, and Mannheimer prior art.
Excelliance Mos Corporation v.Force MOS Technology Co., Ltd.
The PTAB affirmed all nine claims of Force MOS Technology’s ’634 patent after finding Inergy Technology’s IPR unsubstantiated. The Board held that the petitioner failed to prove anticipation or obviousness over Hirler, Shiraishi, and Kobayashi references.
AdvanCell Pty Ltd. v.Sciencons AS et al.
AdvanCell Pty Ltd.'s PGR petition against Sciencons AS et al. was instituted by the PTAB, leading to a trial on grounds of anticipation and obviousness (102/103) and indefiniteness (112). The Board preliminarily adopted all three constructions proposed by the Petitioner for element [1.C], setting up complex claim construction issues for trial.
Ascend Elements, Inc. v.Duesenfeld GmbH
Ascend Elements, Inc.'s petition against Duesenfeld GmbH's battery recycling patent was denied by the PTAB. The Board found that the Petitioner failed to demonstrate unpatentability based on obviousness or indefiniteness across all challenged claims.
Shenzhen Root Technology Co., Ltd. et al. v.Willow Blossom Holdco Limited et al.
Shenzhen Root Technology Co., Ltd. successfully had its Inter Partes Review petition instituted against Willow Blossom Holdco Limited for infringing on breast pump system patents. The Board found sufficient evidence to proceed with the obviousness claims, allowing the case to move forward to trial.
SAMSUNG ELECTRONICS CO., LTD. et al. v.OMNI MEDSCI, INC.
The PTAB issued a Final Written Decision on Remand, finding all 23 claims of Omni MedSci’s wearable pulse‑oximeter patent unpatentable. Apple’s arguments on obviousness over multiple prior‑art references prevailed.
SAMSUNG ELECTRONICS CO., LTD. et al. v.OMNI MEDSCI, INC.
Apple’s wearable physiological‑monitoring patent was declared entirely unpatentable after Samsung’s PTAB challenge, with the Board finding the claims obvious over a combination of prior‑art references covering optical sensors, pulse‑rate modulation, spaced emitters, and reflective surfaces.
SAMSUNG ELECTRONICS CO., LTD. et al. v.OMNI MEDSCI, INC.
Apple prevailed in IPR2020‑00175, with the PTAB finding all six challenged claims of the ’299 patent unpatentable as obvious over Lisogurski, Carlson, Mannheimer and Park references.
Canadian Solar (USA) Inc. et al. v.Trina Solar Co. Ltd.
The PTAB found all 11 challenged claims of the solar cell patent unpatentable based on obviousness (35 U.S.C. § 103). The Board determined that combining prior art references, particularly Chang and Jin, would motivate an ordinary skilled artisan to make the claimed structure with a reasonable expectation of success.
uPI Semiconductor Inc. v.Force MOS Technology Co. Ltd.
The PTAB found claims 1 and 3–5 of Force MOS’s 7,812,409 patent unpatentable as obvious over Kobayashi and Hshieh, while claims 2 and 6 remained patentable.
SIG Sauer Inc. v.True Velocity, Inc.
SIG SAUER and True Velocity settled their IPR dispute over patent 8,561,543, leading the Board to dismiss the proceeding before trial.
Shenzhen Root Technology Co., Ltd. et al. v.Willow Innovations, Inc. et al.
Shenzhen Root Technology Co., Ltd. successfully petitioned the PTAB to institute an IPR against Willow Blossom Holdco Limited's breast pump patent (11813381). The Board found a reasonable likelihood of unpatentability based on multiple grounds of obviousness under 35 U.S.C. § 103, citing combinations of prior art references like Chang and Fang.
Padagis US LLC et al. v.Neurelis, Inc.
Padagis US LLC successfully challenged claims 1-18 of Neurelis, Inc.'s patent under grounds of obviousness (103) and lack of written description (102). The Board found a reasonable likelihood that the invention is unpatentable, based on combining prior art references Gwozdz and Meezan.
Samsung Electronics Co., Ltd. et al. v.Molecular Rebar Design, LLC
Samsung successfully challenged all 16 claims of Molecular Rebar Design’s ’282 patent covering carbon‑nanotube binders for batteries. The Board found the claims obvious over prior art and adopted a construction that “discrete” does not require non‑attachment.
Samsung Electronics Co., Ltd. et al. v.Molecular Rebar Design, LLC
The PTAB instituted an inter partes review of Samsung's challenge to claims 1‑8 of U.S. Patent 8,808,909 and granted Samsung’s motion to join the earlier IPR filed by LG Energy Solution, consolidating the disputes.
LG Energy Solution, Ltd. v.Molecular Rebar Design, LLC
The PTAB affirmed all claims of LG Energy Solution’s lithium‑ion battery patent after finding the challenger’s obviousness arguments unsupported. The Board emphasized that Ohata’s masterbatch embeds carbon nanotubes, preventing the required ionic attachment, and rejected the petitioner’s speculation about resin removal.
Cipla Limited v.Gilead Sciences, Inc.
The PTAB denied Cipla Limited's IPR petition against Gilead Sciences regarding patent 11,744,802, citing the advanced stage of parallel district court litigation and lack of compelling merits.

Bio-Rad Laboratories, Inc. v.California Institute of Technology et al.

Bio-Rad Laboratories, Inc. v.California Institute of Technology et al.
The PTAB issued a Final Written Decision rejecting all claims (1-19) of the '921 patent. The Board rejected arguments based on obviousness and novelty, particularly concerning multi-occupancy droplet detection in multiplexed biochemical assays.
Cargill, Incorporated v.Bunge Loders Croklaan USA, LLC
The PTAB denied institution of an IPR challenge brought by Cargill against Bunge Loders Croklaan regarding vegetable fat composition claims. The Board found that the petitioner failed to overcome obviousness grounds, specifically rejecting arguments based on hindsight bias when converting prior art data.
Cargill, Incorporated v.Bunge Loders Croklaan USA, LLC
Cargill's request for rehearing was denied after the PTAB previously denied institution of IPR against Bunge Loders Croklaan USA regarding a vegetable fat composition patent. The Board found that Cargill’s arguments relied on hindsight bias, specifically in selecting prior art examples to meet claimed triglyceride ranges.
Shenzhen Root Technology Co., Ltd. et al. v.Chiaro Technology Ltd.
The PTAB instituted the IPR, finding that Petitioner demonstrated a reasonable likelihood of prevailing on at least one challenged claim. The Board declined discretionary denial despite arguments regarding parallel litigation and prior art cumulative nature.
Shenzhen Root Technology Co., Ltd. et al. v.Chiaro Technology Ltd.
The PTAB issued a Final Written Decision determining that all 46 challenged claims of the '380 patent were unpatentable. The petitioner successfully argued obviousness (103) over various prior art references, including Chang, Fang, and Yuen, concerning breast pump systems.
Recycled Plastics Industries, LLC et al. v.Tangent Technologies LLC et al.
Recycled Plastics Industries and Tangent Technologies settled their dispute over U.S. Patent 10,981,350 B1, prompting the PTAB to terminate the IPR before it was instituted.
Bio-Rad Laboratories, Inc. v.California Institute of Technology et al.

Samsung Display Co., Ltd. et al. v.Pictiva Displays International Ltd.
Samsung Display Co., Ltd.'s IPR petition against Pictiva Displays International Ltd. was denied by the PTAB. The Board found that the petition lacked compelling merits and determined the dispute was better suited for District Court resolution due to complex claim construction issues.
