Tandberg attempts to patent open source code

An anonymous reader writes: As if the current situation with software patents wasn't bad enough, it appears a new phenomenon is emerging: companies are watching the commit logs of open source projects for ideas to patent. In this case, Tandberg filed a patent that was step-by-step identical to an algorithm developed by the x264 project — a mere two months after the original commit. The particular algorithm is a useful performance optimization in a wide variety of video encoders, including Theora.
