Ericsson Inc. et al. v.XR COMMUNICATIONS LLC
The PTAB issued a Final Written Decision rejecting the petitioner's contentions that the patent was unpatentable over Agee or in combination with Butler. The Board found Petitioner failed to meet its burden of proof, specifically regarding how prior art disclosed critical signal processing limitations.
MICROSOFT CORPORATION et al. v.LiTL LLC
The PTAB denied institution of the IPR, finding that the Petitioner failed to demonstrate a reasonable likelihood of success in proving unpatentability. The claims related to graphical user interfaces (GUI) were challenged under 35 U.S.C. § 103(a).

The PTAB denied WIZ, Inc.'s IPR petition against Orca Security Ltd., finding that a statutory disclaimer covered all challenged claims.
MICROSOFT CORPORATION et al. v.LiTL LLC
Microsoft and others failed to prove obviousness against LiTL LLC's display adaptation patent (9003315) before the PTAB. The Board found that Petitioners could not demonstrate sufficient particularity regarding content filtering, denying the unpatentability challenges.
Samsung Electronics Co., Ltd. et al. v.Headwater Research LLC
The PTAB institution decision allows Samsung Electronics Co., Ltd. to challenge 30 claims of U.S. Patent No. 8,588,110 B2 based on obviousness (35 U.S.C. § 103). The Board adopted the Petitioner's view of the level of ordinary skill in the art and conducted claim construction for key 'means for' limitations. This sets the stage for a full IPR review against Headwater Research LLC.
Visa, Inc. v.Cortex MCP, Inc.
Visa's claims against Cortex MCP were upheld by the PTAB Director in a review of the Final Written Decision. The Board confirmed that Oborne discloses the token verification limitation central to Visa's patent.
Motorola Solutions, Inc. v.STA Group, LLC
Motorola Solutions successfully petitioned the PTAB, leading to trial on all challenged claims of STA Group's patent (8145249).

This decision moves the dispute toward full trial, significantly advancing Motorola's position.

TikTok Inc. et al. v.NTECH Properties, Inc.

The USPTO denied institution for IPR2026-00109 after reviewing the merits, finding that the petitioner could not demonstrate a reasonable likelihood of prevailing on at least one challenged claim.
Visa, Inc. v.Cortex MCP, Inc.
Visa, Inc., successfully petitioned for institution in a high-stakes IPR against Cortex MCP, Inc.'s digital credentialing patent (9251531). The Board adopted key claim constructions favorable to the Petitioner and found sufficient evidence of obviousness based on prior art references.
National Beef Packing Company, LLC v.Institute for Environmental Health, Inc.
National Beef Packing Company successfully petitioned to institute IPR against the '771 patent, establishing a reasonable likelihood of success over at least one claim. The Board adopted Petitioner's definition for 'validation,' clarifying that it merely requires a sample test negative, rejecting the Patent Owner's broader interpretation regarding commercial release.
Geneoscopy, Inc. v.Exact Sciences Corporation
The PTAB instituted an IPR in a colorectal cancer screening case, finding a reasonable likelihood that Geneoscopy's challenged claims are unpatentable. The Board accepted the petitioner's argument that combinations of various prior art references teach every limitation of the claims with a reason for combination.
QUALCOMM INCORPORATED et al. v.COBBLESTONE WIRELESS, LLC,
Qualcomm successfully secured institution for its IPR against Cobblestone Wireless, despite the petition being substantively identical to a previously instituted Samsung proceeding. This decision emphasizes that lack of 'road-mapping' alone is insufficient grounds for discretionary denial when the claims are highly relevant.
Microsoft Corporation v.Proxense, LLC
The PTAB denied Microsoft's request to institute Inter Partes Review (IPR) against Proxense's patent 8,886,954. The denial was based on a procedural condition that required prior non-institution in a related proceeding.

National Beef Packing Company, LLC v.Institute for Environmental Health, Inc.

National Beef Packing Company, LLC v.Institute for Environmental Health, Inc.
The PTAB instituted the IPR after finding a reasonable likelihood of success that the challenged claims are unpatentable based on obviousness (35 U.S.C. § 103). The Board analyzed key claim terms, preliminarily construing 'validated' as a negative test result rather than release into commerce.
Microsoft Corporation v.Proxense, LLC
The PTAB denied Microsoft's request to institute Inter Partes Review against Proxense's patent because a related review was already underway.
AMAZON.COM, INC. et al. v.Nokia Technologies Oy
Amazon challenged Nokia's video coding patent (7532808) at the PTAB, arguing that the claims are obvious over prior art references like Karczewicz and Frojdh. The Board found a reasonable likelihood of unpatentability for several claims, supporting Amazon’s position on key skip coding mode limitations.
