 So I still have people that I speak to, should they sign a nondisclosure? It's helpful, it's extra protection, it's not necessary. Reason for doing that is if you file a patent and you get them assigned a nondisclosure agreement, if your patent ultimately doesn't get granted and fall back on the nondisclosure agreement, I'm always careful when providing that advice. Other way around, it's not really that safe. So if you rely on just the nondisclosure agreement, you're taking the risk as a nondisclosure agreement is basically it's a contract and contracts are enforceable between two parties. That's how a nondisclosure agreement is, like party A agrees not to disclose the idea and both of them signed, but party A is the idea to their second cousin or an unaffiliated company. The entire burden is on the inventor to prove that the leak happened through the person that signed the contract. And if they do sue, that person could legitimately testify in court that they don't know you. They've never spoken to you, never written to you. So don't rely just on the nondisclosure. If you have the patent pending, there's no harm to additionally having a nondisclosure filed.
