If someone else owns a trademark registration for the domain name your company chooses, they may be able to have your domain name put on hold so you can t use it and eventually have it transferred to them. The best way to prevent this from happening is to obtain a trademark registration yourself. If your company s domain name is used to indicate the source of its goods or services, then the domain name may be registrable as a trademark. Consult your trademark counsel. The best reason to register a trademark is to increase the value of your company, particularly the goodwill of the business.
Accountants have formulas to incorporate the value of trademarks into the value of the business.
Another reason is to make it easier to go after infringers. There are several advantages courts give owners of registered marks that are not available to owners of unregistered marks. A registration also provides your company a defense if it is sued for infringement or if someone tries to take its domain name. Registration also puts the whole world on notice for subsequent database searchers. Simply put, with all the benefits that come with registration, its not worth trying to get around the registration requirement.
