Patent Validation
A patent protects. Validation tells you if it will sell.
You filed, or you are about to. Before you spend on prototypes, tooling, or a licensing push, check the market side of your invention.
Educational content, not legal advice. For questions about your own filing, talk with a registered patent attorney or patent agent.
Why do patented products still fail?
Patented products fail for the same reasons unpatented ones do. The patent adds one more cost to the pile. None of these problems show up in a patent office. They show up in a conversation with a buyer.
No real buyer
The customer is described as anyone who needs it, which is the same as no customer.
No proof of demand
Friends and family said they would buy it. Strangers never did.
A price that does not work
The cost to make it plus what a retailer or licensee needs lands above what buyers will pay.
Not different enough
A buyer already has something that does the job well enough.
The four checks
The same four checks used before tooling work after a filing too. Answer all four with evidence and the patent supports a real plan. Miss one and you have found the gap cheaply.
Is there evidence of demand?
Strangers describing the problem unprompted, asking to buy, or pushing back with real reasons. Compliments are not a Demand Signal.
Can you define and reach the buyer?
One sentence naming a specific person, frustration, and situation, plus where you would actually find them.
Will buyers pay a viable price?
What similar products sell for, and whether the numbers leave room for you or a licensing partner.
Is it meaningfully different?
The alternatives a buyer uses today, including doing nothing, and one sentence on why yours wins.

What validation covers, and what an attorney covers
Market validation
- Who the buyer is and where to reach them
- Evidence that strangers want it
- Pricing against alternatives
- What makes it different to a buyer
- Which path to test: license, sell, or make it
Patent attorney or agent
- What can be protected and how
- Preparing and filing applications
- Disclosure and timing questions
- Deadlines and patent office responses
- Legal review of agreements
The two jobs fit together. See working with patent attorneys for how, and Do Patent Attorneys Validate Market Demand? for the short answer.
Who is this for?

Patent Validation FAQ
What is patent validation?
Patent validation is the market-side check of a patented or patent-pending invention. You test whether a specific buyer wants it, whether the price works, and whether it beats the alternatives. It is not a legal review of the patent, which belongs with a registered patent attorney or agent.
Does a patent mean my product will sell?
No. A patent can protect an invention from being copied, but it says nothing about whether buyers want it or will pay your price. Sales depend on demand, a reachable buyer, a workable price, and real differentiation. Those are market questions that need their own evidence.
Can I validate after I have already filed?
Yes. Validation is useful at any stage, and doing it after filing still helps you decide whether to spend on prototypes, tooling, or a licensing push. Earlier is cheaper, but a late answer is far better than never finding out, and it can shape what you do next.
Is InventMentors a law firm or patent service?
No. InventMentors does not provide legal advice and does not file patents. Questions about patent timing, disclosure, and filing belong with a registered patent attorney or patent agent. InventMentors helps with the commercial question: will anyone buy this, and which path should you test first?
