Cabello Hall Zinda Defeats Samsung’s IPR Petitions

We are pleased to announce that the U.S. Patent Trial and Appeal Board has denied Samsung’s petitions for inter partes review, which challenged the validity of two patents directed towards media measurement technology.

Led by Stephen Zinda, the post grant team prepared comprehensive preliminary responses identifying weaknesses in the petitions. Based on those responses, the Board determined that Samsung failed to demonstrate a reasonable likelihood that any challenged claim was unpatentable and DENIED institution of both petitions.

This victory comes on the heels of the team defeating six IPR petitions filed by Roku against several of the same patents. The patents are currently being asserted against Samsung in Anonymous Media Research Holdings, LLC v. Samsung Electronics Co., Ltd., 2-23-cv-00439 (E.D. Tex.). Trial is set for September 8, 2025.
