Patent Lawyer vs. Patent Agent

Patent agents are the only professionals, other than the inventor itself, who can file for patent applications. They can also represent their clients during patent prosecution.

Additionally, a patent lawyer can represent their clients when defending against or suing for patent infringement cases. They can also provide legal advice on how to proceed with commercialization or litigations for the patent.

However, lawyers can’t represent their clients during prosecution or file for their applications unless they are also patent agents. Lucky for you, we’ve only listed firms with lawyers who are also patent agents.

What to Look for in a Patent Lawyer?

1. Qualifications

Your patent lawyer should have an excellent and up-to-date understanding of patent laws in Canada and in other countries where you want to apply for a patent. Make sure they also have the qualifications from CIPO so they can represent you there as well as in court.

Their qualifications will also determine their range of services. So, a patent lawyer who is also an agent will be able to help you from planning, search, and registration, up to the enforcement of your patent rights.

2. Technical background

Patent lawyers should also have a technical background so they can easily understand your idea or inventions. Their technical background will also help them differentiate your idea from other ideas from the same industry and thus, defend your idea against potential infringement cases.

3. Values

You wouldn’t want to hire a lawyer who spills your trade secrets to potential competitors, right? So, make sure your lawyer is trustworthy and honest because you’ll be sharing your secret and valuable ideas.

4. Costs

Lastly, make sure you can pay for the costs of your patent lawyer. Patenting is an investment, so make sure you are putting your money in the right places, lest you lose all your capital before you can even profit from your invention.
