Short Summary
The PTAB issued a Final Written Decision finding claims 22-26 unpatentable under 35 U.S.C. § 103 based on combinations of Danciu and Mahajan prior art. While the Petitioner succeeded for these specific claims, they failed to demonstrate obviousness for claims 1-21 against various prior art references.
Detailed Summary
In this Final Written Decision, the Board addressed challenges to claims 1-26 of patent 8356251, which relate to content delivery and media streaming systems. The Petitioner successfully demonstrated that claims 22 through 26 were unpatentable over combinations of Danciu and Mahajan under § 103(a). However, the Petitioner was unsuccessful in proving obviousness for claims 1-21 against prior art references such as Calvert, Aldrey, Danciu, and Mahajan. Claim construction established 'media player' as software for playing media. The Board also dismissed the Patent Owner’s Motion to Strike as moot.
