I'll take the blame for introducing the assumption regarding the phrase "registered previously" found in the original post. I was hoping that PROXUS would jump back in to clarify.
My interest in this discussion is that I also hold a trademark that corresponds to a ".com" domain name, where the domain name was registered prior to my first use of the mark. (I am the registrant of the ".net" and ".us" domains corresponding to my trademark.) In my case, the registrant of the ".com" domain name does not, and never has, maintained any sort of website (not even a parked site) for the domain. In fact, he doesn't use the domain for any genuine purpose, not even as an email address. Rather, the site is just one among several in his "portfolio" of domain names. And yes, I have spoken with the registrant, and he was very careful NOT to offer it for sale. However, from what he didn't say, it's safe to assume that he that he would sell, but only for much more than I would be willing to pay.
I have considered attempting to yank the name through one of the dispute resolution procedures. But at least for now, since I think my chances of success are slim, I've decided to devote my resources elsewhere. Anyone disagree that my chances are slim?
Although I don't think I have much chance to yank the domain from the current registrant, I hope that I might have a better chance to yank it from whoever eventually buys, since the date of transfer would be after my first use of the trademark. Any thoughts on this approach?
