Can Recent MS Patents Affect Mono and DotGNU?

5p1urge asks: "I really love the Mono and DotGNU projects. As someone who's worked in Java for for over 5 years, I welcome C# and it's buddies to the OpenSource world. However, here's question: as far as I can tell, only the C# spec and System.* assemblies were submitted to ECMA and therefore made officially public. What happens when MS decides that, Linux -is- going to steal valuable income-generating business, and therefore it should use it's newly acquired patents to sue? I'd appreciate comments from IT lawyers / solicitors and individuals with experience in this area, as well as from the wider community. I'm asking this question because I want to code in mono / DotGnu but I'm cautious because I wonder if MS can take it away from us?"
