Short Summary
Google has filed an IPR petition challenging all nine claims of U.S. Patent 7,804,891, alleging obviousness over a combination of cellular‑standard prior art. The petition argues the examiner missed critical references and that discretionary denial factors do not apply.
Detailed Summary
In a petition for inter partes review, Google LLC seeks to invalidate claims 1‑9 of U.S. Patent 7,804,891, which covers a device and method for judging communication quality in wireless systems. The challenger asserts that the claims are unpatentable under 35 U.S.C. § 103 because the combined teachings of the IS‑54‑B standard, Dent, Yeh, Mårtensson (Ground 1) and IS‑54‑B, Dent, Su (Ground 2) render the invention obvious. Google contends that these references were not considered during prosecution, constituting a reversible error, and that no discretionary denial under §§ 314(a) or 325(d) is warranted, urging the Board to institute the proceeding.
