Short Summary
Charter Communications' IPR petition against Iarnach Technologies' DOCSIS auto‑configuration patent is challenged by the patent owner, who argues the petitioner's reply adds new, undisclosed arguments, violating the IPR rules. The patent owner seeks dismissal of the new arguments and confirmation of the patent's validity.
Detailed Summary
In IPR2024‑01287, Charter Communications seeks to invalidate claims of Iarnach Technologies' U.S. Patent No. 9,287,982 covering service auto‑configuration methods for DOCSIS provisioning. The patent owner’s sur‑reply contends that the petitioner's reply introduces new arguments and claim constructions—particularly regarding the “service auto‑configuration” and “back‑office management system” terms—that were not disclosed in the original petition, constituting an impermissible “unfair surprise.” Citing statutory requirements under 35 U.S.C. §§ 311 and 312 and numerous Federal Circuit precedents, the owner argues the Board must reject these late‑filed theories and uphold the patent’s validity.
