Samsung Electronics Co. Ltd. et al. v.Maxell, LTD.
Maxell defends its ’650 Patent on personalized content delivery, arguing that Samsung’s cited prior art (Shindo, Sasaki, Futa, McClellan) does not teach the claimed one‑to‑one content‑to‑device mapping. The response also challenges the petitioner's expert credibility and claim construction.
Roku, Inc. v.VideoLabs, Inc.
Roku, Inc. successfully convinced the PTAB that its claims related to conditional access and DRM systems were unpatentable over prior art (Russ). The Board found a reasonable likelihood of prevailing on both anticipation (§102) and obviousness (§103), leading to institution of the IPR.
Roku, Inc. v.VideoLabs, Inc.
Roku, Inc. successfully convinced the PTAB to institute its challenge against VideoLabs' patent claims under 35 U.S.C. § 102 (Anticipation). The Board found sufficient support for anticipation over prior art 'Russ,' while denying institution on obviousness grounds.
