Columbia Sportswear is suing Wuxly, an outerwear company registered in Canada, for allegedly infringing a design patent covering its heat-reflective material. The lawsuit (U.S. number 655,921) was filed on April 27. According to the plaintiff, Wuxly’s Sabertooth line of jackets uses lightweight underlining that infringes on Columbia’s Omni-Heat reflective material. More specifically, the patent covers the lining’s “ornamental design.” Columbia said that it first informed Wuxly of its infringing products in Nov. 2020, but Wuxly continued to sell its Sabertooth products with the allegedly infringing underlining. Columbia wants the district court to ban its Canadian rival from selling the jacket line involved in the lawsuit. In addition, Columbia is seeking disgorgement of Wuxly’s profits, a “reasonable royalty” based on the allegedly infringing sales, and treble damages.
