Short Summary
Maxell opposes Samsung’s IPR petition on U.S. Patent 8,180,198, arguing the prior art does not disclose the claimed playlist and dubbing features and that the petitioner’s expert testimony is merely argumentative.
Detailed Summary
In its preliminary response to Samsung’s petition for inter partes review of U.S. Patent 8,180,198, Maxell, Ltd. contends that the petitioner has failed to show a reasonable likelihood of success. The patent owner asserts that none of the eight cited prior‑art references—Nagaoka, Benyamin, Nara, Imada, Watanabe, Looney, Platt, and Kaplan—teach the specific claim limitations, and that the petitioner’s expert declaration merely repeats petition arguments without independent data. Maxell also highlights the petitioner’s failure to provide complete claim constructions, a violation of 37 C.F.R. §42.104(b)(3). Accordingly, Maxell urges the PTAB Director to deny institution of the IPR.
