About

Patents protect new inventions. Applying for one is a technical and legal process, and the rules are strict. Only a registered patent agent can do this work for others in Canada. Lawyers who want to do it must also be on the register.

The licence is issued nationally by the College of Patent Agents and Trademark Agents, which keeps the register of patent agents. Once you are on the register, you can work in a law firm, a patent agency, a company, or a university or research body. Many patent agents have a science or engineering degree, and some are also lawyers. The licence is useful in roles such as patent agent, patent attorney, pharmaceutical patent attorney, intellectual property lawyer and IP litigator.

How to get it

  1. Build your technical background
    Most people start with a degree in science, engineering or a related field. This helps you understand the inventions you will write about.
  2. Gain supervised experience
    You work under a registered patent agent and learn to draft and file patent applications. This usually takes a period of years of practical training.
  3. Prepare for the qualifying exams
    You study patent law and practice. Many candidates study alongside their work for a few months or longer.
  4. Pass the qualifying exams
    You sit written papers that test your knowledge of patent law and your drafting skills. You must pass all the required parts.
  5. Apply to be entered on the register
    Once you have met the requirements, you apply to the College of Patent Agents and Trademark Agents. They check your application and add you to the register.

The exam

The qualifying exam is a set of written papers. They test patent law and practice, and they test how well you can draft and assess patent documents. Candidates usually prepare for several months. Sitting the exams is done in stages, so you can pass some parts and return for others if needed.

Keeping it

You must stay on the register to keep acting for others. This means renewing your registration on a regular schedule and paying the renewal fee. You should also keep your knowledge of patent law up to date, since the rules and practice change over time.
