Short Summary
CommScope Technologies LLC filed an IPR petition challenging 49 claims related to modular cassette systems used in fiber optics. The petitioner argues that the challenged claims are anticipated or rendered obvious by prior art combinations involving Fukui, Sedor, and Sauter.
Detailed Summary
This Petition challenges the validity of Belden Canada ULC's patent (11656422) on grounds of anticipation (§ 102) and obviousness (§ 103). The petitioner presents multiple lines of attack, including claims anticipated by Fukui alone, or rendered obvious through combinations such as Sauter combined with Fukui, or Sedor combined with Sauter. Central to the dispute are claim construction issues regarding 'two, three, four, and six standard width units' and whether components must be 'directly adjacent.'
