Tinnus Enterprises, LLC v. Telebrands Corp., No. 16-1410 (Fed. Cir. 2017)
Annotate this CaseTinnus, which produces a toy for filling water balloons, sued Telebrands for infringement of Tinnus’s 066 patent, which relates to a system for simultaneously filling multiple containers (such as balloons) with fluid. Telebrands sells a competing product. Both products attach to a hose and fill multiple water balloons at once by channeling the water into the balloons through a set of hollow tubes. Tinnus obtained a preliminary injunction. Shortly thereafter, the Patent Trial and Appeal Board instituted a Post-Grant Review proceeding for the patent, finding all claims were more likely than not invalid based on the same arguments considered by the district court. The Federal Circuit upheld the preliminary injunction, stating that it was “unable to find any clear error in the district court’s conclusion that Tinnus had demonstrated irreparable harm.” The court also upheld findings of insufficient motivation to combine disparate prior art references and that the claim term “substantially filled” is not indefinite.
