Short Summary
Cisco has filed an IPR petition seeking to invalidate QPrivacy’s U.S. 11,106,824 patent, asserting that all 20 claims are obvious over prior‑art IDS patents (Burns, Yang, and Wittenberg). The petition also argues that discretionary denial is inappropriate.
Detailed Summary
In IPR2025‑00837, Cisco Systems, Inc. petitions the PTAB to institute a review of QPrivacy USA LLC’s U.S. Patent No. 11,106,824, which claims methods for dynamically managing private data between a remote server and a user device. Cisco contends that claims 1‑20 are unpatentable under 35 U.S.C. §103 because they merely combine teachings from three prior‑art intrusion‑detection system patents—Burns (U.S. Pat. 8,341,724), Yang (U.S. Pat. 8,291,495), and Wittenberg (U.S. Pat. Pub. 2005/0078668)—that disclose all the asserted features. The petition further argues that the Board should not apply discretionary denial under §§ 325(d) or 314(a), citing prompt filing and lack of a stay. No claim constructions are requested, and the proceeding is currently at the petition stage.
