This post is primarily one for Dr. C., however I would like to hear from anyone who has thoughts on the subject.  My post concerns an RSS patent.  From my scant research (primarily Google), it looks like Microsoft is involved, or planning to be involved in, patent litigation against other holders of RSS technologies.  Is this so?  They did file an application for RSS inside a web browser.  The inventor is Amar S. Gandhi plus seven others.  The issue seems to center around whether or not this patent application is based on prior art.  That is, is it merely an improvement on something previously patented.  What are your thoughts?  I’ve included a link to a website where I got some of my information.  I’d like to hear your thoughts.
