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.
