Non-Disclosure Agreement

A non-disclosure agreement (NDA) can protect your confidential information in an employment situation, when discussing a possible joint venture or the sale of your business or when you need to disclose information about your invention.

You do not need a confidentiality agreement when consulting with or disclosing information to your lawyer or patent attorney because they are legally bound to keep all client information in the strictest of confidence.

If however, you need to discuss your invention with someone before you apply for a patent, such as a machinist to help you build a prototype, or engineer who will help with the specification document or investor who will assist with funding, it is vital to have a non-disclosure agreement in place.

Remember that it is a requirement for a patent to be new i.e. not publicly known or previously disclosed, to qualify for patent registration, unless such disclosure was made "in confidence".

SIDEBAR: For employment of business situations you could use the following when you need to disclose confidential information:

Employee Confidentiality Agreement

Financial Confidentiality Agreement - for disclosure of financial statements when selling a business.

Whatever information you choose to disclose about your invention, it is best to do so in writing and to clearly mark such information (including samples, drawings, plans, descriptions etc.) as "CONFIDENTIAL" to avoid disputes about the nature of the information. It is also a good idea to add the date of disclosure on such material.

For example, if during discussions you orally disclose additional information not recorded as yet, you can minute such information in writing and ask the recipient to acknowledge receipt thereof. This is not a legal requirement though but good practice!

An NDA can be "one-way" - where only one party discloses information, or "mutual" - where both parties exchange confidential information.

The invention confidentiality agreement following here is drafted as a one-way agreement. You could sign an NDA prepared by the other party if they too will be disclosing their confidential information. You can replace the word "Inventor" in our template with "Disclosing Party" if you prefer.

Our sample non-disclosure agreements provided here are for informational purpose only and you must consult with legal counsel for advice and assistance.
