I have a non-disclosure agreement that I signed to not disclose confidential information of the disclosing party.
“Confidential Information” shall include all information or material that has or could have commercial value or other utility in the business in which disclosing party and receiving party are engaged in; and any other projects that parties named in this agreement collaborate on, as well as other related information regarding specific projects and products.
However, the disclosing party never signed the NDA.
Does this mean that the NDA is not valid and any "confidential information" can then be disclosed?
