Short Summary
Google’s IPR against a proximity‑based wireless patent resulted in the Board finding 20 of 22 challenged claims unpatentable, leaving only claims 37 and 43 intact.
Detailed Summary
In IPR2020-00931, Google challenged Target Corporation’s ’359 patent covering methods for a central server to exchange information between wireless devices using short‑range (e.g., Bluetooth) and long‑range (e.g., Wi‑Max) communications. The Board instituted the review on all asserted grounds and evaluated anticipation under 35 U.S.C. § 102(b) and obviousness under § 103(a) using Perttila and, for a subset of claims, Insolia as prior art. After extensive claim‑by‑claim analysis, the Board concluded that 20 claims were unpatentable, while claims 37 and 43 were not sufficiently proven unpatentable. No claim constructions were required. The decision represents a mixed outcome, substantially narrowing the patent’s enforceable scope.
