Short Summary
Innolux files an IPR petition seeking to invalidate claims 1‑3 and 5‑6 of the ‘788 LCD gamma‑correction patent, arguing the claims are obvious over four prior‑art references. The petition requests institution and argues no denial under §§ 314(a) and 325(d).
Detailed Summary
In a petition for inter partes review of U.S. Patent No. 7,557,788, Innolux Corporation challenges claims 1‑3 and 5‑6, asserting that the patented method of calibrating liquid crystal displays using reprogrammable, non‑volatile gamma reference control is fully disclosed in the prior art. Four grounds are presented, each combining different earlier patents—Liaw, Greene, Da Costa, and Matsui—to demonstrate that a person of ordinary skill would have found the claimed features obvious under 35 U.S.C. § 103. The petitioner also meets standing and eligibility requirements, seeks institution, and argues the Board should not invoke discretionary denial under §§ 314(a) and 325(d). No settlement or denial is indicated at this stage.
