HTC has won a case in the U.S. that alleged the Taiwanese smartphone maker had infringed on several digital camera patents controlled by FlashPoint Technology. See also HTC One X review.

On Tuesday, the U.S. International Trade Commission (ITC) said in a notice it had found that HTC's smartphones did not violate FlashPoint's patents.

The company had filed the complaint in July, 2010, and had sought to ban the import of HTC smartphones to the U.S.

FlashPoint, based in Peterborough, New Hampshire, had originally also named handset makers Nokia, Research In Motion, and LG Electronics in its patent infringement complaint. The other three companies, however, had arrived at settlements, according to the ITC.

"The Commission's determination validates our position that we respect protected innovations.  We look forward to returning to doing what we do best: creating innovative mobile experiences and providing choice to consumers," HTC's general counsel Grace Lei said in a statement.

FlashPoint could not be immediately reached for comment.

HTC, the largest smartphone vendor in the U.S., has been facing several patent battles in connection with its products. The biggest has been with Apple, which has also asked the ITC to ban the import into the U.S. of HTC's smartphones, because the devices allegedly violate several Apple patents.
