The U.S. International Trade Commission has said it will investigate a complaint of patent infringement filed by Apple against HTC. Bloomberg reports that in the complaint Apple is targeting HTC’s Flyer tablet computers as well as the Droid Incredible, Wildfire, EVO 4G and Desire phones, claiming that they infringe five patents related to software architecture and user interfaces in portable devices, hardware for touchscreens, and movement sensors. Notably, the ITC ruled last month that HTC violated two Apple patents in some of its Android-based phones. “HTC respects intellectual property and will continue to protect and defend its protected innovations,” Grace Lei, general counsel at HTC, said in an e-mail. “We will fully cooperate with the ITC’s investigation and look forward to showing that we are not in violation of any of Apple’s patents.” HTC released its seven-inch Flyer tablet in the U.S. in March.
