Short Summary
The PTAB held that claims 1‑18 of the ’042 patent are unpatentable, finding them obvious over a combination of Limont, Wright, Xu, and Polson references.
Detailed Summary
In IPR2024-00809, the Patent Trial and Appeal Board reviewed claims 1‑18 of U.S. Patent No. 9,198,042 B2, which relate to a secure execution environment for device‑assisted services in mobile devices. The Petitioner (a consortium of major wireless carriers) asserted that the claims were obvious under 35 U.S.C. § 103, relying on the Limont, Wright, Xu, and Polson prior‑art references. The Board affirmed the Petitioner's position, concluding that the prior art taught or suggested every limitation of the independent claim and its dependents, and that a person of ordinary skill would have been motivated to combine the teachings with a reasonable expectation of success. No rebuttal evidence was presented by the Patent Owner, leading the Board to declare all 18 claims unpatentable.
