An inventor should usually have a nondisclosure agreement in place before the first detailed technical conversation about an unfiled idea, and treating that as routine rather than as an accusation is the practical answer to the confidentiality question. That is the position of Trevor Lambert, who co-owns Enhance Innovations, an invention design and product development firm founded in 2010 in Champlin, Minnesota. We asked him to walk through when NDAs help, when they do not, and where inventors get confused.
What an NDA does and does not do
Q: Inventors hear conflicting advice. What does an NDA actually accomplish?
A: “It creates a written agreement that the person you are talking to will not disclose or use what you tell them outside the purpose you both agreed on. That is real and useful. What it does not do is replace a patent. An NDA is a private contract between two parties. A patent is a federal right against the world. People sometimes treat the signature as if it protects the idea everywhere. It protects the conversation.”
The distinction matters because a public disclosure can affect patent rights. The United States allows a one-year grace period after certain disclosures by the inventor, but many other countries do not, according to the United States Patent and Trademark Office. Keeping early conversations confidential preserves options an inventor may not want to give up yet.
When a confidentiality agreement is the right tool
Lambert lists the moments he sees it matter most. “Before you describe how the thing works to a contractor, a potential manufacturer, or anyone whose help you need before you have filed. That is the gap. After a provisional or a full filing, you have patent pending status and a different kind of footing. Before filing, the NDA is what stands between a private conversation and a public one.”
Where inventors get it wrong
Q: What is the common mistake?
A: “Two opposite ones. Some inventors refuse to talk to anyone without a signed NDA and then wonder why larger companies will not engage. Many established companies will not sign an inventor’s NDA before they have even seen a sell sheet, because they review too many ideas to take on that risk blindly. Other inventors swing the other way and describe everything to anyone, no agreement at all. The workable middle is to protect the genuinely confidential technical detail and be comfortable sharing the high-level pitch.”
He ties this to how his firm presents work. The Enhance model is virtual-first, built around renderings, a CAD model, and optional animation, and Lambert notes that digital materials make confidentiality easier to manage. “You decide exactly which files a given party sees, and under what terms. That is harder when you are shipping a physical unit from one meeting to the next.”
The professional handles this routinely
Q: Should an inventor expect a design or development firm to work under an NDA?
A: “Yes. For us an NDA before the first technical conversation is normal. It is not a sign of distrust, it is how the work is supposed to start. A firm that designs, engineers, and helps present inventions handles confidential material every day, and the agreement just sets the expectation in writing.”
Keeping design, engineering, and licensing under one roof reduces the number of outside parties who need access to sensitive detail in the first place. “Every extra freelancer is another person who has to be brought inside the agreement. Fewer hands on the confidential material is simpler to control.”
A sensible default
The pattern Lambert recommends is modest and repeatable: file something before wide disclosure when you can, use an NDA for the pre-filing technical conversations that require it, and accept that the public-facing pitch will travel more freely than the engineering detail. Small businesses, which the U.S. Small Business Administration reports account for the overwhelming majority of American firms, rarely have a legal department to lean on, so the habit has to be the inventor’s own.
“I cannot promise an NDA will prevent every problem,” he says. “What I can say is that a routine agreement before the first technical talk, and a filing before you go public, are the two habits that keep your options open.”
