Crocs has been sued by U.S.A. Dawgs, a family-owned company in Las Vegas that has been making clogs with EVA soles since 2006. Requesting a jury trial on the issue, the anti-trust complaint alleges that Crocs has been misleading consumers for more than a decade into believing that its “Croslite” closed-cell resin is an exclusive, proprietary product, whereas it as a commonly used ethyl vinyl acetate. It challenges the validity of Crocs' patents and suggests that Crocs has been using “sham” lawsuits to defeat its competitors and raise its market share to more than 90 percent.
