Short Summary
The PTAB found all 17 challenged claims unpatentable under 35 U.S.C. § 103(a) for the solar cell technology. The Board concluded that Petitioner successfully demonstrated obviousness over Chang in view of Jin, or other combinations.
Detailed Summary
In this Final Written Decision, the PTAB ruled that all seventeen claims related to solar cells are unpatentable under 35 U.S.C. § 103(a). The Board determined that Petitioner successfully demonstrated obviousness by combining Chang and Jin, finding that these references taught necessary structural elements for the claimed invention. While initially addressing arguments regarding hindsight, the Board ultimately clarified that when elements are present together in a single reference, showing obviousness does not require finding a separate motivation to combine them (KSR).
