A patent dispute dating back to 2008 between Stan’s NoTubes and Specialized has been resolved in favor of Stan’s. The dispute centered on Stan’s ZTR rims with Bead Socket technology, a bead hook shape that allowed for easier and more secure mounting of tubeless tires. Specialized released rims in 2008 that used a similar design, and Stan’s filed with a U.S. District Court to protect its patent.
Stan’s won its initial case, and Specialized was forced to pay compensation in 2015. The decision on Monday simply re-affirmed a previous decision by the Patent Trial and Appeal board.
When contacted, Specialized declined to comment on the matter. The company ceased selling the infringing wheels in 2009, and no current product is affected by the District Court’s decision.
“We are pleased to have reached a positive conclusion regarding our rim design patent. The court’s decision further strengthens our patent portfolio,” Stan’s co-owners Stan and Cindy Koziatek said in a statement. “We look forward to continuing the advancement of tubeless wheels for all cycling applications.”
