Before handing over the technical data to the patent agent, a patent agency contract must generally be signed. A formal patent agency contract should include the terms of the contract that the patent agent keeps the technical data confidential. Patent agents may be investigated for their responsibilities in accordance with this clause if technical information is leaked when they obtain it. In addition, China's patent law also has relevant provisions on the confidentiality responsibility of patent agents. If the patent agent obtains the evidence of leakage or theft, it may also be based on the patent law.
Patent agents come into contact with so-called confidential technical data every year, so they generally don't have to worry too much.
