Domain names may be filed as trademarks in accordance with the usual rules and principles of trademark examination. Like any other symbol, a domain name may only be protected as a trademark if, overall, there is the requisite degree of identification with the claimed goods and services. Top level domain names (TLDs) such as .com, .org, .net or .ch are not considered distinctive and are thus not protectable. Combinations of a word from common usage and a TLD are also not protectable.
