US shoe maker Crocs has filed a patent infringement lawsuit against footwear firm Evacol USA. 

"It has recently come to our attention that Evacol has been infringing certain intellectual property rights of Crocs and is attempting to unfairly trade off of Crocs' brand equity," said Crocs brand president Andrew Rees. "Crocs will not tolerate these acts and will aggressively defend and protect its valuable assets."

The suit, which centres around three patents – '858, '354, and '784 – seeks monetary damages as well as a preliminary and permanent injunction restraining Evacol from manufacturing, using, marketing, distributing, selling and importing any footwear that infringes on the patents. 

According to its website, Evacol USA is a Colombian company based in Miami, which designs, produces and distributes footwear in the US, Caribbean Islands, as well as Central and South America. 

Last year, Crocs said it continues to make steady progress in its strategic transformation, despite swinging to a third-quarter net loss of US$24m. Revenue fell 9.4% $274.1m, while margins were impacted by an aggressive clear-out of aged and excess inventory.
