Do You Need an NDA Before Sharing Your Invention?

I tell every inventor who walks into my Fishkill office the same thing: file before you talk. But the world isn't always that simple. Sometimes you need to discuss your invention before you're ready to file. A manufacturer needs technical details to give you a quote. A potential business partner wants to understand what you've built. An investor asks pointed questions.

So the question comes up constantly: do I need a nondisclosure agreement first?

The short answer is that it depends on who you're talking to and whether you've already filed a patent application.

What an NDA Actually Does

A nondisclosure agreement -- sometimes called a confidentiality agreement -- is a contract. The person who signs it agrees not to share your confidential information with others and not to use it for their own purposes. If they violate the agreement, you have a breach of contract claim.

That's it. An NDA doesn't give you patent rights. It doesn't prevent someone from independently developing the same idea. And it's only as good as your ability to enforce it, which means you'd need to prove the breach and be willing to pursue legal action.

Still, an NDA establishes a legal record that the disclosure was confidential. That record matters, especially before you've filed.

Why Filing Date Matters More Than Ever

Since the America Invents Act took effect in 2013, the United States operates under a first-to-file system. The patent goes to the first person who files an application, not the first person who invented. This was a fundamental shift in American patent law.

Under the old first-to-invent system, you could establish priority through lab notebooks and witness testimony. That era is over. Your filing date is what counts now. Every day you delay filing is a day someone else could file first.

This makes pre-filing disclosures risky. If you share your invention without an NDA and without having filed, you're exposed on two fronts: the other party could file their own application, and the disclosure itself could count as prior art against you.

When an NDA Is Essential

Before you've filed any patent application, an NDA is your primary protection when discussing your invention with:

• Contract manufacturers. They need technical specifications. They'll see drawings, dimensions, materials -- the kind of detail that fully discloses the invention. Get the NDA signed before you send anything.
• Potential business partners. Joint ventures, licensing discussions, co-development agreements -- all of these involve sharing proprietary technical information. An NDA sets the ground rules.
• Engineers and designers. If you're hiring outside help to develop a prototype or refine your design, they need to understand what you've invented. Protect yourself contractually before the first meeting.

I've worked with inventors throughout the Hudson Valley -- from Kingston to Beacon to Newburgh -- who needed to talk to local machine shops or fabricators before they had a patent application on file. In every case, we put an NDA in place first. It takes a day. The protection is worth it.

When an NDA Is Impractical

There are situations where asking for an NDA simply won't work.

Investor pitches. Most venture capitalists and angel investors refuse to sign NDAs. They hear hundreds of pitches. Signing a confidentiality agreement for each one would create impossible legal exposure. If an investor won't sign, that's standard practice, not a red flag.

Trade shows and conferences. You can't get an NDA from every person who stops by your booth. Public demonstrations are, by definition, public.

Conversations with potential customers. If you're testing market interest by describing your product to prospective buyers, you're making disclosures that an NDA would be awkward or impossible to enforce.

The One-Year Grace Period

U.S. patent law provides a limited safety net. Under current patent law (35 U.S.C. 102(b)(1)(A)), if you publicly disclose your own invention, you have one year from that disclosure to file a patent application. After twelve months, your own disclosure becomes prior art that bars you from getting a patent.

This grace period is specific to the United States. Most other countries have no grace period at all -- a public disclosure before filing means you've lost your foreign patent rights permanently.

Don't rely on the grace period as a strategy. It's a safety net, not a plan. I've seen inventors burn through that twelve months faster than they expected, scrambling to file before the deadline.

The Best Approach: File First, Talk Second

A provisional patent application costs a fraction of a full application. It establishes your filing date, gives you twelve months to file the non-provisional, and -- critically -- it lets you mark your invention "Patent Pending."

Once you have a provisional on file, you can discuss your invention freely with manufacturers, investors, partners, and customers. The filing date is established. The clock is running in your favor.

This is the approach I recommend to nearly every independent inventor and startup founder who comes through our door. File the provisional. Get your priority date locked in. Then go out and talk to the world with confidence.

If you're not ready to file -- if the invention isn't developed enough for a provisional application -- then yes, get an NDA in place before every significant conversation. It's not perfect protection, but it's far better than nothing.
