Stride Rite is suing Puma for trademark infringement in a U.S. federal court in Massachusetts. Stride Rite claims that Puma infringes on three of its trademarks that protect a two-stripe design on the foxing band of Pro-Keds shoes. Pro-Keds says it has utilized the ?power stripe? on footwear and shoes since 1968. The complaint cites designer Alexander McQueen's Scarred Street shoes as one example of an infringing Puma shoe style. Stride Rite also alleges that Puma has been aware of its infringement since June 5, 2009, but has declined to stop selling footwear that uses the design on the foxing of shoes. The plaintiff is seeking a jury trial and a permanent injunction against Puma. It also wants the defendant to pay damages and to destroy all footwear and associated selling materials that infringe on the Pro-Keds' Power Stripe.
