Detailed Summary

This Petition challenges 19 claims of patent 10951359, owned by Asustek Computer Inc., which relates to physical layer procedures and CORESET management in wireless communications.

Specifically, Ground 2 demonstrates obviousness combining Nogami with Chatterjee and NTT regarding slot boundary crossings, while Ground 3 relies on Nogami combined with 3GPP standards for expected UE behavior. The PTAB determined that the petition presented compelling merits and met institutional factors under § 314(a) and § 325(d), resulting in institution.
