Short Summary
Maxell’s sur‑reply argues TCL’s IPR petition re‑uses prior art, shows no material error, and fails claim‑construction arguments, urging the PTAB to deny institution.
Detailed Summary
In its sur‑reply to TCL’s petition for inter partes review of U.S. Patent No. 10,650,780, Maxell, Ltd. argues that the petitioner’s single ground merely repeats the Lawther reference already considered during prosecution and adds no new prior art. The patent owner asserts there is no material error because the petition re‑hashes earlier arguments, and contends that the petitioner’s claim‑construction positions are unsupported and would fail under any construction. Accordingly, Maxell urges the Patent Trial and Appeal Board to deny institution of the petition.
