Detailed Summary

In IPR2023‑00988, the Patent Trial and Appeal Board reviewed Samsung Display’s U.S. Patent No. 10,854,683 B2 covering a pixel arrangement structure for OLED displays. Petitioners BOE entities argued that the claims were obvious in view of prior‑art references such as Phan, Matthies, Murai and Yamada. The Board found Phan’s disclosure to fairly suggest applicability to OLEDs and concluded that the combination of Phan with Yamada did not render claim 2 obvious. Patent Owner’s secondary‑consideration evidence was deemed of little weight. Ultimately, the Board declared claims 1,4‑10,13 and 15 unpatentable, leaving claim 2 intact, and granted the petitioner’s first motion to strike in part.
