Short Summary
Lenovo challenged claims related to cyclic advancement in OFDM systems, arguing that the claimed novelty is obvious under 35 U.S.C. § 103. The petitioner asserts that 'cyclic advancement' is merely a predictable equivalent of known techniques found in prior art references like Dammann and Hervin.
Detailed Summary
This Petition challenges multiple claims within Patent No. 7623439, asserting obviousness based on the combination of existing wireless communication technologies. The petitioner argues that the concept of 'cyclic advancement' is not novel but rather a predictable modification or equivalent to established processes like 'cyclic delay.' Specifically, Ground 1 combines Dammann and Hervin for diversity implementation, while Ground 2 further integrates Kannan to show obviousness in technical implementations such as ASIC usage or specific guard interval settings.
