Short Summary
The PTAB issued a Final Written Decision finding that claims 1–7 and 9–14 were unpatentable over prior art references. The petitioner successfully demonstrated obviousness under 35 U.S.C. § 103, particularly regarding the combination of Onishi and Flowerdew for independent claim 1.
Detailed Summary
The Board concluded that the challenged claims are unpatentable over various combinations of prior art, including Baarman392, Partovi, Onishi, and Flowerdew. The key finding was that a Person Having Ordinary Skill in the Art (POSITA) would be motivated to combine general teachings—such as alignment from Flowerdew applied to Onishi's inductively coupled system—to achieve optimization. Furthermore, the Board adopted a narrow construction for 'substantially different,' limiting it to frequencies within near-linear regions of the frequency-amplitude graph.
