CUPERTINO, California—March 2, 2010—Apple® today filed a lawsuit against HTC for infringing on 20 Apple patents related to the iPhone’s user interface, underlying architecture and hardware. The lawsuit was filed concurrently with the U.S. International Trade Commission (ITC) and in U.S. District Court in Delaware.

“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,” said Steve Jobs, Apple’s CEO. “We think competition is healthy, but competitors should create their own original technology, not steal ours.”

Earlier today, Apple issued a press release stating that it has filed suit against cell phone manufacturer HTC for patent infringement. No mention of Android or Google was in the press release. But the actual legal complaints, which we’ve obtained and embedded below, make no bones about it. As expected, this lawsuit is about Android. HTC, of course, is one of the largest manufacturers of Android handsets.

The complaint filed in U.S. District Court in Delaware targets: “certain mobile communication devices including cellular phones and smart phones, including at least phones incorporating the Android Operating System (collectively, “the Accused Products”).” And the complaint filed with the U.S. International Trade Commission specifically calls out the various HTC Android phones (including the Nexus One, Magic/myTouch 3G, Dream/G1, Hero, and Droid Eris) as the main offending products. By going after the biggest Android manufacturer, Apple is putting all Android cell phone makers—and by extension Google— on notice. Is there any doubt now why Google CEO Eric Schmidt had to resign from Apple’s board last year? The battle lines are now drawn
