In December of 2008, Crocs Inc. and Skechers Inc. agreed to settle patent litigation (case number 1:08-cv-01450, in the U.S. District Court for the District of Colorado) concerning U.S. D517,789, U.S. D564,208 and U.S. D564,207.  That patent litigation concerned a line of slip-on foam clogs made by Skechers, which Crocs alleged infringed the patents.

On May 20, 2011, Crocs filed a complaint and initiated a new suit against Skechers, case number 1:11-cv-01330, in the U.S. District Court for the District of Colorado.  Crocs alleges the Swifts line introduced in the summer of 2010 by Skechers is an “obvious imitation” of Crocs’ original shoe design for the CROCBANDTMmodel footwear, which is protected by U.S. D610,784.  Crocs also alleges Skechers breached a settlement agreement of September 23, 2010, stemming from Crocs’ contact with Skechers’ around the time the Swifts line was introduced.
