While Friday’s decision may have been a setback for PXG, it seems to be only part of the company’s strategy in pursuing patent infringement against the P790 irons. Lawyers for PXG filed additional complaints on Thursday and Friday against the four largest golf retailers in the U.S. for patent infringement violations tied to their sales of P790 irons. Worldwide Golf, the parent company of golf retail brands Edwin Watts and Roger Dunn among others, was named in a suit filed by PXG in U.S. District Court in California on Thursday. On Friday, PXG filed suits against PGA Tour Superstore, Golf Galaxy and Dick’s Sporting Goods in U.S. District Court in Illinois.
