Lambert Intellectual Property Law (mountain panorama)



A trademark is any mark that distinguishes a product or service provided by one company from products or services provided by others. Trademarks exist at common law by virtue of acquiring goodwill from extensive use, and it is not always essential to register a trademark. However, in some cases, registered trademarks may take precedence over common law trademarks, and registration of a trademark, whether used or proposed to be used, is recommended. In some countries, registration is mandatory for protection of a trademark.

A valid trademark allows its owner to prevent others from using a mark, in the country in which the trademark is valid, in a manner that would be likely to be confusing with the valid trademark. A registered trademark may be renewed indefinitely in 15 year periods by paying the appropriate fees.

Lambert IP Law has extensive experience in the filing, prosecution and litigation of trademarks in Canada, and in other countries.
