Latest Centripetal SCOTUS Petition Challenges Material Changes in Claim Construction Post-Markman

Centripetal Networks filed a Supreme Court petition challenging Federal Circuit's affirmation of materially different claim construction without meaningful opportunity to adjust infringement position. Case stems from 2018 lawsuit against Cisco in Eastern District of Virginia over patents 9,686,193 and 9,203,806 for packet filtering technology. After judicial recusal issues and remand, Judge Hanes adopted narrower claim constructions leading to noninfringement ruling. Centripetal argues Federal Circuit lacks standards for distinguishing "clarifications" from new claim construction requiring due process notice.
