Nike Sues Puma for Alleged Infringement of Footwear Patents

Nike is also asserting one patent related to its Nike Air technology, a footwear sole structure designed to protect an athlete’s joints and muscles from impact forces. U.S. Patent No. 7401420, titled Article of Footwear Having a Fluid-Filled Bladder with a Reinforcing Structure. Issued in July 2008, it claims an article of footwear with a sole structure having a bladder enclosing a fluid that provides an outward force on a first surface and a reinforcing structure extending around a portion of the bladder. Nike alleges that Puma first began infringing on the ‘420 patent in November 2017 when it released Jamming footwear that incorporated a fluid-filled bladder for foot support.

Crocs loses inter partes reexam, will appeal rejection of design patent for ornamental footwear

Boulder, CO-based shoe manufacturer Crocs, Inc. (NASDAQ:CROX) had a design patent rejected by the U.S. Patent and Trademark Office. The patent struck by the USPTO is U.S. Patent No. D517789. Issued in March 2006 and assigned to Crocs, it protected the ornamental design of footwear. The design patent illustrations attached to the ‘789 design patent showcase the well-known Crocs design featuring holes in the footwear material around the front of the foot and a strap behind to hold the footwear in place against a person’s heel… The Examiner refused to recognize a priority claims of earlier filed applications dating back to June 23, 2003. According to the Examiner, the shoe that is the subject of the ‘789 design patent was not adequately disclosed prior to May 28, 2004, making an earlier priority date claim impossible to recognize.
