===Disclosure agreements===
There are two sets of agreements associated with the transfer of know-how agreement: disclosure and non-disclosure agreements, which are not separately parts of the principal know-how agreement.{{citation needed|date=September 2008}}

The initial need for disclosure is due to the requirement of a licensee firm to know what is the specific, unique, or general content of the know-how that a licensor firm possesses that promises value to the licensee on entering into a contract. Disclosure also aids the potential licensee in selecting among competitive offers, if any. Such disclosures are made by licensors only under non-disclosure or confidentiality agreements in which there are express undertakings that should the ultimate license not materialize, the firm to whom the disclosure is made will not reveal, or by any manner apply, any part of the disclosed knowledge which is not in the public domain or previously known to the firm receiving the information.

Non-disclosure agreements are undertaken by those who receive confidential information from the licensee, relating to licensed know-how, so as to perform their tasks. Among them are the personnel of engineering firms who construct the plant for the licensee or those who are key employees of the licensee who have detailed access to disclosed data, etc. to administer their functions in operating the know-how-based plant. These are also in the nature of confidentiality agreements and carry the definition of know-how, in full or truncated part, on a need-to-know basis.
