Short Summary
The PTAB issued a Final Written Decision finding all 13 claims unpatentable by preponderance of the evidence. The Board found that the challenged claims were obvious over various combinations of prior art references, including Weaver combined with Lee ’053 and Song.
Detailed Summary
In this IPR, the Petitioner successfully demonstrated that the patent-in-suit claims related to pixel structure/OLED devices were unpatentable under 35 U.S.C. §§ 102 and 103. The Board adopted a broad construction of 'auxiliary electrode,' allowing for power lines or bus lines, which facilitated the finding that POSITAs would have been motivated to combine references like Weaver with Lee ’053 or Song to achieve lower resistance and voltage drop in OLED structures.
