Water Pik, Inc. v. Med-Systems, Inc.

Med-Systems, Inc., sells its products under the federally registered trademark SinuCleanse and two similar marks. Water Pik, Inc., which traditionally sold oral irrigators and showerheads, registered the trademark SINUSENSE with the intention of selling sinus-irrigation devices under the brand name “SinuSense.” It sued Med-Systems seeking a declaratory judgment that its use of the SinuSense brand name did not infringe on any of Med-Systems’ marks. Med-Systems counterclaimed for trademark infringement and unfair competition under the Lanham Act. Ruling that the SinuSense brand was not likely to cause consumer confusion, the district court awarded summary judgment to Water Pik on the counterclaims and dismissed Water Pik’s declaratory-judgment claim as moot. Finding no error in the district court's decision, the Tenth Circuit affirmed. View "Water Pik, Inc. v. Med-Systems, Inc." on Justia Law
