Short Summary
SIG Sauer has filed an IPR petition seeking to invalidate all 19 claims of True Velocity’s polymeric ammunition cartridge patent, alleging anticipation and obviousness over multiple prior‑art references. The petition outlines seven statutory grounds under §§ 102 and 103 and requests institution of the review.
Detailed Summary
In a petition for inter partes review (IPR2025‑00861), SIG Sauer Inc. challenges U.S. Patent No. 8,561,543 owned by True Velocity, Inc., asserting that claims 1‑19 are unpatentable. The petitioner relies on seven grounds, invoking 35 U.S.C. § 102 for anticipation (Daubenspeck for claims 1, 7, 18 and Dittrich for claim 1) and 35 U.S.C. § 103 for obviousness, combining Daubenspeck with Chung, Kay‑Clough, Nonte, Anderson, and Chung again. Detailed claim‑by‑claim analyses cite motivation to combine, reasonable expectation of success, and extensive prior‑art disclosures. The petition includes expert declarations, cites relevant case law, and concludes that the challenged claims are unpatentable, requesting the PTAB to institute the IPR and cancel the claims.

Jumio CorporationvsFaceTec, Inc.
Jumio Corporation successfully secured institution at the PTAB against FaceTec, Inc., establishing a reasonable likelihood of unpatentability for 24 claims related to facial recognition. The Board found that combinations of prior art references (Derakhshani/Tanii and Zhang/Tanii) rendered the claims obvious under 35 U.S.C. § 103.
Samsung Electronics America, Inc. et al.vsTelcom Ventures LLC
Samsung Electronics has filed an IPR petition seeking to invalidate Telcom Ventures’ ’756 patent covering smartphone‑based mobile payments. The challenger relies on the Jain and Dua prior‑art references to argue obviousness of all 18 claims.
Samsung Electronics Co., Ltd. et al.vsEmpire Technology Development LLC
The PTAB found claims 25-28 unpatentable over Li and Siam, based on obviousness (103). The Board adopted a specific construction of 'idle power consumption' as power consumed while powered on and waiting to send data. However, the attempt to prove obviousness for claim 29 failed due to impermissible hindsight bias.
PacifiCorp et al.vsMES, Inc.
The Director granted review of multiple IPRs involving PacifiCorp and Birchtech Corp., vacating prior institution decisions. The Board is now remanded to determine which single petition, out of two filed per patent, should be instituted.
Stingray Group Inc. et al.vsHernandez-Mondragon, Edwin et al.
The PTAB issued an institution decision for IPR2025-00349 on June 13, 2025. A later director‑review request by the patent owner was filed after the 14‑day deadline and was deemed untimely, so the Board will not consider it.
