The United States Patent and Trademark Office (USPTO) declared a new rule as of August 2019. All foreign based trademark applications and actions under the jurisdiction of the "Trademark Trial and Appeal Board (TTAB)" are required to be performed by a US licensed attorney.
The new rule applies to all trademark applicants and parties whose legal residence or dominant place of business is outside of the US. Such parties will need a US licensed attorney to be represented before the USPTO in all trademark matters.
In light of the new rule, we advise our clients, having their principal business outside of US but operating in USA, to contact us for guidance as soon as possible given the fact that the rule is already implemented. If you are a Canadian trademark applicant or party to a US trademark action contact us at email@example.com
