Short Summary
Ascentcare Dental Products has petitioned the PTAB to invalidate Solmetex’s 12,290,418 intraoral device patent, alleging obviousness over six prior‑art references. The petition seeks cancellation of 25 claims covering the isolation mouthpiece.
Detailed Summary
In an Inter Partes Review petition filed on June 24, 2025, Ascentcare Dental Products, Inc. challenges U.S. Patent No. 12,290,418 owned by Solmetex, LLC. The petitioner asserts that claims 1‑9, 11‑17, and 19‑28 are unpatentable under 35 U.S.C. § 103, citing prior‑art patents and publications by Black, Park, Baughan, Johnson, Hirsch, and Zheng. Detailed arguments describe how a person of ordinary skill would combine these references to arrive at the claimed intraoral isolation mouthpiece, and how the examiner’s lack of prior‑art rejections contributed to overbroad claim scope. The petition requests the Board institute review and cancel the challenged claims.
