(or Confidentiality Agreement)
It is essential that an inventor does not publicise details of an invention before a patent application is filed. Often, the inventor will wish to discuss the invention at an early stage, for example, to get a third party to make a prototype, or to enquire if a company with relevant expertise would be interested in investing in the invention. These, and any other discussions taking place before a patent application is filed, need to be in confidence. Therefore, before divulging any information to a third party, for any purpose, before the patent application is filed, a non-disclosure agreement (also known as a confidentiality agreement) should be signed on behalf of the third party.
