patent all challenged claims upheld

Altice USA, Inc. et al. v.Touchstream Technologies, Inc.

· IPR2024-01263

Google’s inter partes review of Touchstream’s ’251 patent failed; the Board found no unpatentable subject matter for claims 1, 2, and 5‑9. The petition relied on Muthukumarasamy and Hayward, but the Board concluded the references did not teach the required signal flow or media‑player identification.

· IPR2024-00981

The PTAB issued a Final Written Decision finding all 20 claims of the '188 patent unpatentable based on obviousness (35 U.S.C. § 103).

The decision involved extensive claim construction, notably finding that 'associated with' includes models implemented in a base station and that 'representation of' allows for modeled signals.

patent all challenged claims unpatentable

Good Sportsman Marketing, LLC v.--

· PGR2024-00034

Good Sportsman Marketing successfully convinced the PTAB that all 19 claims of patent 11736855 were unpatentable. The Board found the claims invalid under both obviousness (35 U.S.C. § 103) and various indefiniteness grounds (35 U.S.C. § 112(b)).
