Can I register a .CO using a Trademarked company name? Normally, I would have thought not. However, I spend a lot of time going through the 'Report Completed Sales' thread on NP trying to reverse engineer why certain names sell. I take the sold domain, go through Linked In, OpenCorporates, DotDB, Dofo, Google. NameBio etc. One tool I always look at is Uspto.gov and their Trademark TESS database Almost ALL of the .co domains reported in that thread are of registered Trademarks. I guess the problem I am having is kind of a what came first. The chicken or the egg question. It's a good strategy to register a domain with a lot of potential end users, right? So someone looks through OpenCorporates, LinkedIn etc. Wow there are 5,000 companies using the word: CoolWord. However, one of these companies owns the TM on CoolWord I wouldn't think I could register the domain: CoolWord.co But this seems to be the EXACT strategy that is working for .co sales. I am not going to list the domains here, but DM me if you want some examples. I don't get it.
