Looking for a patent agency to handle a patent, do I have to give the other party a technical disclosure first? No need to sign a confidentiality agreement?

Patent agency contracts usually contain confidentiality clauses, so confidentiality agreements are generally not signed separately. If you entrust an agent to apply for a patent, you must trust the other party completely without reservation, otherwise the application may not be authorized, and the patent law also stipulates the confidentiality responsibility of the agency, so the agency will not violate the law, otherwise the consequences will be serious.
