Apple Inc. on Tuesday said it was suing smart-phone maker HTC Corp., alleging that the Taiwan company infringed on 20 Apple patents associated with the popular iPhone.
The lawsuits were filed with both the U.S. International Trade Commission and the U.S. District Court in Delaware and accuse HTC of stealing the iPhone's user interface, underlying architecture and hardware, Apple said.
Apple introduced the iPhone in 2007 and has since sold more than 40 million units, the Cupertino, Calif., company said. HTC produces the Nexus One phone, which uses the Android operating system and is designed and sold by Google Inc. directly to consumers.
"We can sit by and watch competitors steal our patented inventions, or we can do something about it. We've decided to do something about it," Apple Chief Executive Steve Jobs said in a statement. "We think competition is healthy, but competitors should create their own original technology, not steal ours."
