A Power of Attorney, POA in short, is a legal document that authorizes an entity to represent or act for another person, usually, in the managing of the person’s property, business or private affairs. The former is called the Attorney or Agent whereas the latter is commonly known as the Principal.

In Trademarks, a Power of Attorney is required to appoint an Attorney on your file so he/she can represent you before the respective Trademarks Office.

Having said that, in many countries including the US, UK, Europe, Canada and Australia you don’t need to sign a POA for a standard trademark application (power of attorney is already implied when you entrusted your attorney/agent trademark registration). However, there are countries, such as, China, Mexico, Russia and India where a POA signed by the owner or any other person legally bound to the owner is required in order to file a trademark application.

In the US, when an applicant wishes to replace its existing attorney and appoint a new attorney, it needs to sign a Power of Attorney authorizing the new attorney to prosecute the trademark application.
