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.
