Internet domain and trademarks

The choice of a domain name has become an important business decision. A domain name is registered by you to enable Internet users to locate your company's site on the web.

A domain name is a name by which a company or organisation is known on the internet. It usually incorporates the company name or another identifier. 

To register a domain name you must apply to an accredited Registrar. 

A list of accredited and accreditation-qualified Registrars can be found on the Internet Corporation for Assigned Names and Numbers web site. 

Being the owner of a registered trademark  does not automatically entitle you to use that mark as a domain name. The main reason being, that the same trademark can be registered for different goods or services and by different proprietors. Also, someone may have already, and quite legitimately, registered the domain name, perhaps with its use being connected with unregistered goods or services. 

The opposite also applies, if your domain name has been properly registered, it does not automatically follow that a similar trademark will satisfy the requirements for trademark registration, and/or it may be confusingly similar to someone else’s earlier trademark. 

If you feel that a domain name has been registered unlawfully or maliciously we suggest that you take appropriate legal advice. Alternatively, you can get advice from Nominet UK, who also offer a Dispute Resolution Service for UK domain names.
