Detailed Summary

This IPR petition challenges 11 claims related to modular fiber optic cassette systems (Patent No. 11435542) based on grounds of anticipation (102) and obviousness (103). The petitioner contends that prior art references, including Fukui, Sedor, and Sauter, either individually or in combination, disclose the claimed features. Specifically, they argue Fukui discloses elements meeting the claims without rails, while combinations involving Sauter render the remaining limitations obvious. The arguments center on interpreting structural features like cassette widths and adjacency.
