Short Summary
The PTAB issued a Final Written Decision finding most claims (1-12 and 14-18) unpatentable based on obviousness over prior art. Claims 13 and 19-24 were found patentable, despite significant dispute over claim construction terms like 'media stream.'
Detailed Summary
In this Final Written Decision, the Board analyzed claims of U.S. Patent No. 8,145,704 B2 challenged by TikTok Inc. The majority of the claims (1-12 and 14-18) were found unpatentable based on obviousness over references such as Whitehead, Marcus '904, and Cristofalo/Marcus '904. While the Board adopted a broad interpretation for certain terms like 'an output signal,' it ultimately rejected Petitioner's arguments regarding teaching or suggestion across multiple grounds. Conversely, claims 13 and 19-24 were upheld as patentable due to deficiencies in the Petition's mapping and antecedent basis arguments against them.
