As a patent agent, your responsibilities include around working with inventors as they pursue patent applicants. You help individuals or companies with an invention go through the patent application process or take other steps to protect their intellectual property, such as registering a trademark. As a patent agent, you search existing patents and then help the inventor refine their application based on your findings. You may also collect evidence and research patent violations on behalf of a client. However, since you are not an attorney, you do not represent clients in court.
