It looks like to me that if MS wants to patent something they will give it their best shot.  However, when I reread the article I referred to in my earlier post, I saw things a little bit differently.  That is, it seems like MS is trying to get their RSS patent by means of going around the issue.  If they’re granted the patent for the RSS management of an operating system, isn’t that effectively getting the RSS patent itself?  Just some food for thought.
