A weekly summary of the precedential patent-related opinions issued by the Court of Appeals for the Federal Circuit and the opinions designated precedential or informative by the Patent Trial and Appeal Board.

Cap Export, LLC, et al. v. Zinus, Inc., et al., No. 2020-2087 (Fed. Cir. (C.D. Cal.) May 5, 2021). Opinion by Dyk, joined by Bryson and Hughes.

Zinus owns a patent directed to an "assemblable mattress support." Cap Export filed a declaratory judgment action against Zinus, alleging that the claims are invalid and not infringed. The district court awarded Zinus summary judgment of no invalidity, relying on the testimony of Zinus's then-president and testifying technical expert. The parties then stipulated to a final judgment of infringement, validity, damages in the amount of $1.1 million, and a permanent injunction.
