Patent Attorney vs. Patent Agent

Patent agents are engineers or scientists who have passed the patent bar exam, and their work is limited to representing inventors before the U. S. Patent & Trademark Office. Patent agents write patent applications, file them with the Patent Office, and prosecute the case until the application is allowed and issues as a patent. Preparing and prosecuting patent applications is what patent agents do.

Patent attorneys, on the other hand, can do everything a patent agent does plus a lot more because they also have a law degree. Patent attorneys can represent you in court in an infringement suit (or any other suit), draft licensing agreements, handle copyright and trademark issues, provide infringement opinions, and they can even prepare your will. A patent attorney can be considered as a, "one-stop shop."

If a patent attorney and a patent agent are preparing or prosecuting a patent application, there's no difference, except perhaps, the price they charge.
