Short Summary
The PTAB issued a Final Written Decision finding that claims 1-11 are unpatentable over combinations of prior art references (Froitzheim, Gan, Sheats). Claim 12 was not shown to be unpatentable. The Board found the Petitioner met its burden regarding reasonable expectation of success for several claims.
Detailed Summary
In this Final Written Decision, the PTAB analyzed multiple grounds of obviousness under 35 U.S.C. § 103 concerning front contact solar cells. The Board ultimately determined that Claims 1 through 11 were unpatentable over various combinations of prior art references, including Froitzheim, Gan, Sheats, Borden-575, and Li. For instance, the combination of Froitzheim and Gan was found to render claim 9 obvious based on a reasonable expectation of success. Conversely, the Board rejected arguments regarding Claim 12, finding that the disclosure did not support the 'formed over' limitation. The Patent Owner's motion to exclude evidence was denied.
