Acoustic Technology, Inc. v. Itron Networked Solutions, Inc. (Fed. Cir. Feb. 13, 2020)

The Federal Circuit held that the patent owner had waived the argument that an inter partes review is time-barred under 35 U.S.C. 315(b) because it failed to raise the argument before the Patent Trial and Appeal Board.
