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

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

Apple is not suing over multitouch, but rather a bunch of other software. Meanwhile, Apple is already tied up in a patent lawsuit with Nokia, claiming Nokia is stealing Apple technology. Nokia says Apple is stealing its technology. Kodak is also suing Apple claiming technology theft.
