Short Summary
The PTAB initiated a sua sponte Director review of several IPRs involving TikTok and Cellspin Soft, staying the cases while it re‑examines institution decisions tied to RPI and sovereign‑entity arguments.
Detailed Summary
In a June 5, 2025 order, the USPTO Director opened a sua sponte review of six inter partes reviews (IPR2024‑00757, ‑00759, ‑00760, ‑00767, ‑00768, ‑00769, and ‑00770) that challenge patents owned by Cellspin Soft, Inc. The review was prompted by the Patent Owner’s contentions that TikTok failed to name the Chinese Communist Party as a real party‑in‑interest and that TikTok, as a foreign‑controlled entity, might not qualify as a “person” under Return Mail precedent. The Board rejected those arguments, but the Director determined the issues merit reconsideration. All IPRs are stayed pending a forthcoming opinion.
