Companies evaluating an outside invention look at four things first: whether the product fits their existing line, whether it is protected, whether it can be made at a sensible cost, and whether the pitch materials let them judge all three quickly. Flash and personal passion rank far lower than inventors expect. We asked Trevor Lambert, co-owner of Enhance Innovations, an invention design firm based in Champlin, Minnesota since 2010, to walk through what actually gets reviewed.
Fit comes first
“A buyer’s first filter is brutal and fast,” Lambert says. “Does this belong in our catalog? If a company sells kitchen tools and your product is a garden gadget, the quality of your renderings does not matter. They pass. So inventors should pitch the right companies before they worry about polishing the pitch.”
He tells inventors to study a target’s existing line before sending anything. “Match the shelf. A product that sits naturally next to what they already sell gets a real look. A product that would force them into a new category usually does not.”
Protection is the second gate
“The next question is ownership,” Lambert says. “Is there a filing? A provisional application is enough to start the conversation in most cases. It establishes a filing date and gives you 12 months, which the USPTO explains in its provisional application material. Buyers want to know the idea is staked before they invest in it.”
He is careful not to oversell what a filing does. “Patent pending is not a guarantee a patent issues. It tells a company you have a position they can build on. That is what they need to start, not a promise of the finish.”
Cost to manufacture decides the deal
The third filter is money, but not the inventor’s money. “Companies think about their cost to make it,” Lambert says. “If your product needs tooling that runs into serious capital, or materials that push the retail price past what the category supports, they do the math fast. A great idea that costs too much to build is a no.”
This is why Lambert pushes design and engineering to consider manufacturing from the start. “Design for how it gets made, not just how it looks. A CAD model that a factory can quote is worth more than a beautiful render that hides a part nobody can mold affordably.”
The materials that let them judge
The fourth filter is the pitch package itself. “Give them what they need to decide in one sitting,” Lambert says. “Clean renderings from multiple angles. A CAD model with real dimensions. A short animation if the function needs showing. A one page sell sheet that states what it is, who it is for, and why it fits their line. That is a professional package. A napkin sketch and a paragraph is not.”
Lambert notes that the broader economy runs on small inventors getting these basics right. The U.S. Small Business Administration’s Office of Advocacy reports small businesses represent 99.9 percent of American firms, data available on the SBA site. “Most products pitched to manufacturers come from small operators,” he says. “The ones who present like a company get treated like one.”
What companies do not care about
Lambert is blunt about misplaced effort. “They do not care how long you worked on it. They do not care about your personal story unless it sells the product. They do not care that you are sure it will be a hit. They care about fit, protection, cost, and clarity. Everything else is noise in that first review.”
He ties the discipline to how Enhance runs as one integrated team. “Because our designers, engineers, and licensing people work together, the package answers all four questions at once. The render matches the CAD, the CAD matches a real manufacturing path, and the sell sheet speaks to the buyer’s catalog. Separate freelancers rarely produce something that consistent.”
His closing advice is plain. “Stop trying to wow them. Try to answer their questions before they ask. A pitch that does that respects their time, and respect is what gets a second meeting.”
