Short Summary
TikTok Inc.'s challenge to Cellspin Soft's patent was instituted by the PTAB, finding a reasonable likelihood that at least one challenged claim is unpatentable. The Board focused on obviousness (35 U.S.C. § 103) over prior art references including Hiroishi, Kahn, and Bluetooth specifications. This decision sets up trial proceedings to determine if the combination of existing technologies renders the patent claims invalid.
Detailed Summary
The Patent Trial and Appeal Board (PTAB) instituted review in this IPR proceeding, finding a reasonable likelihood that at least one challenged claim of U.S. Patent No. 11659381 is unpatentable over prior art. The petitioner, TikTok Inc., asserted multiple grounds of obviousness (§ 103), primarily relying on the combination of Hiroishi (self-portrait camera/Bluetooth), Kahn (location-based image processing/HTTP), and Bluetooth specifications. While the Patent Owner raised various arguments, including discretionary denial under § 325(d) and written description issues, the Board determined that Petitioner adequately demonstrated material error in prosecution history to overcome these bars. The institution decision moves the case toward trial, where the specific teachings of the prior art references regarding new-data detection, polling, and HTTP usage will be litigated.
