Confidentiality agreement
From Bilat-Wiki
Also known as non-disclosure agreement (NDA), refers to the written agreement that parties use when they wish to disclose information and ideas in confidence. This agreement therefore establishes the obligation of the recipient (i.e. the legal person to whom the information is disclosed) to not disclose the information and ideas to third parties. A confidentiality agreement is crucial for an inventor or any other party that needs to protect confidential information.
