Short Summary
TikTok Inc. challenged Cellspin Soft, Inc.'s patent (US 11659381) in a Petition, arguing that the claims are obvious over combinations of prior art references including Hiroishi, Kahn, and Bluetooth. The PTAB found sufficient grounds for institution, noting that both discretionary tests favored proceeding with the case.
Detailed Summary
TikTok Inc. filed an opening request for review (Petition) against Cellspin Soft, Inc.'s patent US 11659381, asserting invalidity under 35 U.S.C. § 103. The challenger presented two primary grounds of obviousness: first, over Hiroishi in view of Kahn and Bluetooth; and second, over Singh129 in view of Singh906. TikTok argued that a Person Of Ordinary Skill In The Art (POSITA) would have been motivated to combine these elements due to the technological environment at the time. Despite the complexity of the arguments, the Board determined that both the Advanced Bionics Test (§325(d)) and the Fintiv Factors (§314(a)) favored institution, leading to the case being instituted.
