Short Summary
The PTAB issued a Final Written Decision finding claims 22-26 unpatentable under § 103(a) based on combinations of prior art (Aldrey and Mahajan). However, the Board upheld the patentability of claims 1-21, concluding that Calvert did not remedy the necessary 'converting' step.
Detailed Summary
In this Final Written Decision, the Patent Trial and Appeal Board addressed challenges to claims 1-26 of U.S. Patent No. 8356251. The Board determined that while claims 22 through 26 were obvious over combinations of Aldrey and Mahajan, rendering them unpatentable under 35 U.S.C. § 103(a), the remaining claims (1-21) survived the obviousness challenge. This was primarily because the Board found that prior art reference Calvert failed to teach the required 'converting' step present in those earlier claims, despite extensive claim construction establishing 'media player' as software for playing media.
