There are really only three ways to gain trademark rights to a domain name:
(1) Actual use of the domain name in commerce in connection with the provision of goods and/or services. This would involve, for example, putting your domain name in your company logo, and actually providing goods or services to the consuming public under that logo.
(3) Having another company transfer their trademark rights to the domain name to you.
I note that simply owning a domain name, without actually using it as a trademark in connection with legitimate business activities, does not give you any trademark rights to the domain name. This is a common misconception.
