This can largely depend on the circumstances of your relationship. Most of the agreements I see (if they have a duration) have a delay of two to five years. But your NDA should also say that even if the term is over, the disclosing party does not give up any other rights it may have under copyright, patent, or other intellectual property protection laws. Remember that an NDA is simply an agreement where two or more parties agree to keep certain inside information confidential or secret. This type of legal agreement can be a reciprocal or unilateral agreement, but the main purpose is always to protect information or trade secrets essential to the success of a company. If you`re the disclosing party in the deal, you want to cast a wide net, but don`t leave holes. .
