This is a question for my general interest really - but what happens if a legitimate site which has rights in some TM classes starts trading outside of its class? Let's say it's an honest oversight (if that makes a difference). Does the registrant automatically become vulnerable to DRS, should the rights-holder complain, or does the fact that the registrant has rights in the name mitigate its vulnerability to a certain extent? I guess what I'm asking is if an online umbrella-seller oversteps the mark and starts selling galoshes too, can a prior rights-holder in the latter class swoop in and nab his domain? Thanks, P.
