Detailed Summary

In Petition IPR2025‑00597, Yealink (USA) Network Technology Co., Ltd. challenges all 22 claims of Barco’s U.S. Patent No. 11,966,346, which covers a system for making functional devices available to participants of meetings. The petitioner alleges that the examiner materially erred by failing to consider several prior‑art references—Beel, Dinka, Van de Laar, Kaplan, and Christison—that, in combination, render the asserted claims obvious under 35 U.S.C. §103. The petition also highlights new arguments about data transformations, screen‑scraping, and virtual functional devices that were not evaluated during prosecution, seeking institution of the IPR and arguing against discretionary denial under §325(d).
