Short Summary
Pinterest has filed an IPR petition challenging all 20 claims of OpenTV’s ’703 patent, asserting that the claims are obvious over prior art such as Orr, Hsu, Lim, and Hervey.
Detailed Summary
In a petition for Inter Partes Review (IPR2026‑00334), Pinterest, Inc. challenges the validity of every claim (1‑20) of U.S. Patent No. 12,231,703 owned by OpenTV, Inc. The petitioner contends that the patent’s teachings on preserving a playback pipeline during content switches are fully anticipated or rendered obvious by existing technologies. Specifically, the petition relies on Orr for pipeline preservation, Hsu for adaptive bitrate handling, Lim for prefetching content metadata, and Hervey for GStreamer‑based pipeline reuse, arguing that combinations of these references make each claim obvious under 35 U.S.C. §103. The petition seeks institution of the IPR and references related district‑court litigation between the parties.
