if i wanted a site geared toward a persons name. how do i know if that name is trademarked? example johndoeSucks.com
You can go to the US Patent and Trademark Office Website and do a search there for the name. It will tell you if the name/phrase you search for has a trademark or patent, who owns the patents, and what the patents/trademarks declare the name/logo/etc is registered for.
You can run SomeCompanySucks.com even if SomeCompany is trademarked. You just can't profit from the site.
That's not true. Got in trouble a few years ago, almost ended up paying $25,000 for infringement just for having two domains.
