If Interwoven had patented the name TeamSite, would Interwoven be able to get some royalty from Microsoft for using the name TeamSite in their product? :-)
It is not patented (could not be) but it is a registered trademark. I was thinking of setting up a domain called teamsite-experts and learned very quickly I would be sued if I did. Now I do not know if the space matters or if AI does not want to get in a legal batter with MSFT (or maybe they are talking)
