The term of the technical confidentiality agreement for cooked food training depends on the results of negotiation between the two parties. In the confidentiality agreement, the confidentiality period of confidential information is usually agreed, which can be a period of time or forever. If the confidentiality period is not clearly stipulated in the agreement, then according to the provisions of the Anti-Unfair Competition Law of People's Republic of China (PRC), the protected trade secret shall continue to exist until the information has been made public or the trade secret has been obtained through legal channels. Therefore, when signing a confidentiality agreement, it is recommended to clearly stipulate the confidentiality period to avoid ambiguity. At the same time, in order to ensure the safety of trade secrets, it is suggested to stipulate strict confidentiality measures and liability for breach of contract in the agreement, so as to take legal measures to safeguard their rights and interests when necessary.
