A week before this, Brad Smith, Microsofts general counsel, claimed that the Linux kernel violates 42 of Microsofts patents, while the Linux GUIs break another 65.
In addition, the Open Office suite of programs infringes 45 more and an assortment of e-mail programs violate 15 others, the company said, while various other free and open-source programs allegedly transgress 68 more patents.
Microsoft, however, has not taken legal action. In addition, it has refused to identify these patents.
For that matter, Microsoft has refused to say how it determined that its patents were being violated.
Despite all this rhetoric, however, Shuttleworth said he believes that within a few years, "Microsoft themselves will be strong advocates against software patents. Why?
"Because Microsoft is irrevocably committed to shipping new software every year, and software patents represent landmines in their road map [that] they are going to step on, like it or not, with increasing regularity."
