Microsoft: open source software infringes on 235 patents

PC v LinuxFortune Magazine has a detailed article examining Microsoft's relationship to free and open source software. Although the story reads mostly as a history of Microsoft, Linux, and GNU, there are a few interesting new tidbits, including the number of patents Microsoft claims Linux and other free software infringes on: 235.

Microsoft holds thousands of patents for its software, and won't say exactly which bits of code violate which patents. But apparently the Linux kernel alone violates 42 patents, while the Linux graphical user interface infringes on another 65. Microsoft says Open Office violates 45 patents.
