Short Summary
Ascentcare Dental Products petitions the PTAB to invalidate 18 claims of Solmetex’s 2023 intraoral mesh patent, asserting anticipation and obviousness over five earlier dental mouthpiece references. The petition seeks institution of an IPR and cancellation of the challenged claims.
Detailed Summary
In a petition filed on May 20, 2025, Ascentcare Dental Products, Inc. challenges U.S. Patent No. 11,589,969, titled “Intraoral Device with Mesh,” owned by Solmetex, LLC. The petitioner alleges that claims 1‑4 and 6‑19 are unpatentable, citing anticipation under 35 U.S.C. § 102(b) and obviousness under 35 U.S.C. § 103 based on prior‑art references Black, Park, Baughan, Johnson, and Hirsch. Detailed grounds map each claim limitation to the cited references, arguing that the patent owner broadened claim scope after the petitioner’s product launch, rendering the claims obvious or anticipated. The petition requests that the PTAB institute an inter‑partes review and cancel the challenged claims.
