Apple has filed a lawsuit against mobile devices maker HTC. The suit claims infringement of 20 patents related to the iPhone’s user interface, underlying architecture, and hardware.

In the release, Steve Jobs says, “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…We think competition is healthy, but competitors should create their own original technology, not steal ours.”

Taiwan-based HTC was the first company to manufacture a cell phone based on Google’s Android operating system, which has emerged as a significant competitor to the iPhone, AP reports. It’s also making the Nexus One phone that Google is selling directly to consumers.

It looks like the Nexus One, and other HTC phones, may have hit too close to home for Steve Jobs. More info…
