Can patent agents write cases during their graduate studies?

You can't. Patent agents are not allowed to write cases during their graduate studies. Patent agents are restricted by relevant rules. A patent agent refers to a patent agent who has the qualification to apply for a patent and handle other patent affairs on behalf of others. A patent agent should have certain practicing conditions. After approval, China National Intellectual Property Administration will issue a patent agent qualification certificate, and after one year of internship, it will be filed through the patent agent management system.
