So I opened a new domain: Theebooksgalore[dot]com However if you take out "the" it directs you to a site that is for sale with that domain, and they may come after me for copyright/trademark reasons. However this hasn't happened yet and I doubt it will. What do I need to do? Copyright / Trademark it if they haven't already? Please Advise. Thanks, Jason
For a TM status to be active you have to claim USAGE. Parking a domain is not considered commercial usage. You have no worries.
I doubt you would have any problems. Someday if someone uses that other site and puts up a site that's in direct competition with yours then you might hear from them. It doesn't mean they can do anything.
No worries, however I would advice you to develop your site as soon as possible and maybe register it, just to avoid eventual future trademark issue's.
sydneyaus has a good point. If you can get your site on archive.org before the other folks then you at least have proof that your site was up and running before theirs
