Short Summary
Petitioners, including AT&T and Verizon, successfully petitioned to challenge 19 claims of Asustek Computer Inc.'s patent regarding physical layer procedures for CORESET management.

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. The petitioners argue that the claimed features are obvious in view of various prior art references, including Nogami, Chatterjee, NTT, and technical guidance from the 3GPP-Specification. 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.
