C&A Marketing, Inc. (“C&A Marketing”) filed suit against GoPro, Inc. (“GoPro”) on November 3, 2015 in the U.S. District Court District of New Jersey, alleging design patent infringement.  More specifically, in it's complaint C&A Marketing alleges that GoPro's Hero4 Session, a cube-shaped "action" camera, infringes U.S. Patent No. D730,423 (the “D'423 patent”).  

According to C&A Marketing, the D'423 patent protects the Polaroid Cube, created through C&A Marketing's capacity as the exclusive manufacturer, distributor, and marketer of Polaroid® brand mountable action cameras, among other Polaroid® brand products.  Notably, C&A Marketing states that they launched the Polariod Cube in January 2014, at the Consumer Electronics Show (CES) in Las Vegas, Nevada, which was followed by GoPro's release of the "strikingly similar" Hero4 Session camera in 2015. 

Provided below in side-by-side fashion are an image of the Polariod Cube, Fig. 1 from the D'423 patent, and an image of GoPro's Hero4 Session camera, respectively, from the complaint.
