The PTAB granted institution of IPR for Clearwater Paper Corporation against Graphic Packaging International LLC, challenging claims related to biodegradable paper cups based on prior art references Cleveland and Nakagawa.
Zhuhai CosMX Battery Co., Ltd. v.Ningde Amperex Technology Ltd.
The Director granted review of an IPR decision, vacating the institution finding for one set of grounds (Ishigaki-based) because the Board introduced external evidence, but maintained institution for the remaining claims.
Caihong Display Devices Co. Ltd. v.Corning Inc.
Caihong Display Devices has filed an IPR petition seeking cancellation of all 16 claims of Corning’s 2010 glass‑substrate patent, asserting obviousness over Miwa and Bange and anticipation by Miwa. The petition includes an expert declaration and argues that discretionary denial is unwarranted.

POSCO Co., Ltd. successfully petitioned the PTAB to institute an IPR against ArcelorMittal's patent, demonstrating a reasonable likelihood of prevailing on all 25 challenged claims. The Board found sufficient evidence across multiple grounds of obviousness (103) involving various prior art combinations.
Honeywell International Inc. v.DSM IP Assets, B.V. et al.
Honeywell International Inc. challenged the validity of patent 10280532 in a PTAB petition, alleging obviousness based on combinations of prior art references. The Board found that the petitioner demonstrated material error by the Examiner and instituted the case for trial.
Solus Advanced Materials Co., Ltd. et al. v.SK nexilis Co., Ltd.
SK Nexilis seeks a Director Review to keep its copper‑electroplating patent alive after the PTAB instituted an IPR. The patent owner argues the Board misapplied Fintiv factors and over‑relied on unsupported expert testimony.
Solus Advanced Materials Co., Ltd. et al. v.SK nexilis Co., Ltd.
The PTAB institution decision found that the Petitioner demonstrated a reasonable likelihood of prevailing, instituting trial on all 10 claims. The grounds centered on obviousness (35 U.S.C. § 103), arguing that specific properties of electrolytic copper foil could be achieved by combining various prior art references.
Solus Advanced Materials Co., Ltd. et al. v.SK nexilis Co., Ltd.
The Director denied institution of Inter Partes Review in a dispute between Solus Advanced Materials and SK Nexilis, citing the Fintiv holistic assessment.
Solus Advanced Materials Co., Ltd. et al. v.SK nexilis Co., Ltd.

Pascal Technologies v.Cambridge Enterprise Limited et al.
Pascal Technologies successfully secured institution of its Inter Partes Review (IPR) against the '656 patent, challenging claims related to barocaloric cooling agents. The Board adopted a broad interpretation of 'organic material,' supporting the Petitioner's argument that the claimed invention is unpatentable over prior art references like Mañosa and Patel.
Recycled Plastics Industries, LLC et al. v.Tangent Technologies LLC et al.
Recycled Plastics Industries and Tangent Technologies filed a joint motion to terminate IPR No. 2024‑00898, seeking confidential treatment of their settlement agreement under 35 U.S.C. §317. The parties argue the settlement resolves all issues concerning patent 10,981,350.
POSCO Co., Ltd. et al. v.ARCELORMITTAL
ArcelorMittal seeks Director Review of the PTAB’s decision to institute an IPR covering claims 1‑30 of its high‑strength aluminum alloy‑coated steel patent. The owner contends the Board abused its discretion by misapplying Fintiv factors, particularly Factor One and Factor Four, in violation of §314(a).
POSCO Co., Ltd. et al. v.ARCELORMITTAL
POSCO Co., Ltd. successfully petitioned the PTAB to institute an IPR against ArcelorMittal's patent, arguing that multiple prior art combinations render the claims unpatentable under 102 and 103. The Board found sufficient merit in the petition, despite factors favoring discretionary denial, leading to the institution of the review on all 25 challenged claims.
POSCO Co., Ltd. et al. v.ARCELORMITTAL
The Director denied review of institution decisions in the POSCO v. ArcelorMittal IPRs and remanded the case to the PTAB to manage multiple parallel challenges.
