San Francisco 49ers quarterback Colin Kaepernick wants to trademark his bicep-kissing habit. The tattooed star has filed a trademark for "Kaepernicking," a signature move that has swept through the West Coast during the 49ers' playoff run, according to San Francisco 49ers report. Citing the U.S. Patent and Trademark Office website, ESPN.com said Kaepernick registered Jan. 14, and plans to use the image on clothing. The official "Kaepernicking" shirt is made by a company called Sportiqe. Some proceeds go to Camp Taylor, which organizes camps for children with congenital heart defects.
