Short Summary
Iarnach Technologies filed a preliminary response urging the PTAB to deny Charter Communications’ IPR petition on U.S. Patent 9,674,035. The owner contends the petition lacks a reasonable likelihood of success and that the cited prior art does not teach the claimed updates. The Board is asked to reject the petition.
Detailed Summary
In its preliminary response to IPR2025-00473, Iarnach Technologies Ltd. argues that Charter Communications’ petition to invalidate U.S. Patent No. 9,674,035 should be denied. The patent owner asserts that the petitioner has not demonstrated a reasonable likelihood of prevailing on any of the challenged claims (1‑32), highlighting inconsistencies in claim constructions between the parallel district‑court case and the IPR. Ground 1, based on Tsuge, McKinnon, and Noel, fails to teach the updating steps, while Ground 3, relying on Bourgart and Barrow, does not disclose the required notification and change‑determination features. Consequently, Iarnach requests that the Board refuse to institute the review.
