On August 5, 2014, LaRose Industries, LLC filed PGR2014-000008, challenging the validity of U.S. Patent No. 8,684,420, assigned to Choon’s Design Inc., which issued on April 1, 2014, on an application filed on July 26, 2013. In addition to 102 and 103 grounds, which could have been brought in an inter partes review (but not until January 2015), the Petition alleged invalidity under 35 USC 112 for lack of written description, indefiniteness, and lack of enablement.
