IMAX sued CFGS and related companies for theft of intellectual property; this court action was heard on 18 June 2014.[3]IMAX alleged that Gary Tsui, a former employee that worked for IMAX from 1999-2009, stole confidential information on proprietary technology and set-up competing businesses.[4][5][6]Despite a court injunction it was noted that Gary Tsui had ignored the court orders, and his businesses had evolved into a venture known as DMAX, later to change its name to CFGS. In 2014 IMAX won a court victory in Canada upholding that Tsui had stolen the technology to build up his competing company.[7]IMAX hoped that the Canadian court victory would allow successful legal action in China.[7]As of 2015, the status of the legal action in China is uncertain.
