What are the specific requirements for Canadian patent agents to practice before the USPTO?

This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

Canadian patent agents must meet specific requirements to practice before the USPTO under limited recognition:

• They must be registered and in good standing as a patent agent under Canadian law.
• They must apply for limited recognition to the USPTO Director.
• They can only represent Canadian citizens or residents before the USPTO.
• Their representation is limited to the presentation and prosecution of patent applications of Canadian applicants.

As stated in MPEP 402.01: Canadian patent agents are not required to pass the regular patent bar examination to represent Canadian applicants. They need not seek formal recognition to practice before the Office.
