Short answer: most inventors do not need an invention help company. They need one of four specific things: a patent attorney, a product development firm that can build the thing, a licensing agent, or a prototype shop.
The safest legitimate routes are a registered patent attorney for IP, a US product development firm such as LA NPDT or Design 1st for design and manufacturing, an established licensing organization such as inventRight for a license-first strategy, and free public help through the USPTO Pro Bono program, Inventors Assistance Center and your regional Small Business Development Center.
Be extremely cautious with any company that markets to inventors, promises to submit your idea to corporations, and asks for several thousand dollars up front.
What kind of help do you actually need?
Your goal | What you need | Where to go |
|---|---|---|
Protect the idea | Registered patent attorney or agent | USPTO attorney roster, USPTO Pro Bono if you qualify |
Find out if it already exists | Patent and market search | Free USPTO search, our patent search tool |
Prove it works | Working prototype | Product development firm or prototype shop |
Sell it yourself | Design, engineering and manufacturing | Full-service development firm |
License it to a company | Sell sheet, prototype and licensing coaching | Licensing organizations, industry contacts |
Just make one part | 3D print bureau | Local or online print service |
No money at all | Free public programs | SBDC, SCORE, university makerspaces |
How to spot an invention-promotion scam
Legitimate routes for inventors
1. LA NPDT — best for inventors who want the product actually built
Based in: Ruston, Louisiana. Best for: individual inventors who want feasibility, concept design, CAD, a working prototype and a manufacturing path from one US team, at a stage-by-stage cost they can stop or continue at. Not for you if: your goal is to license the idea without building anything, or you need patent prosecution - hire an attorney for that. Start with our free idea analyzer.
2. A registered patent attorney or agent — best for protecting the idea
Only attorneys and agents registered with the USPTO can prosecute a patent. A provisional filing typically costs 1,500 to 3,500 dollars with counsel; a full utility application commonly runs 8,000 to 15,000 dollars. If your income qualifies, the USPTO Patent Pro Bono Program connects inventors with volunteer attorneys at no cost.
3. inventRight — best for a license-first strategy
A long-running coaching organization for inventors who want to license rather than manufacture. Best for: simple consumer products in categories where licensing is common. Not for you if: your product needs real engineering to prove out, or you intend to sell it yourself.

4. USPTO Inventors Assistance Center and Pro Bono — best free help
Government resources that answer procedural questions and, for qualifying inventors, provide free legal representation. There is no reason to pay a promoter for information available here at no cost.

5. SBDC, score and university makerspaces — best for early guidance and cheap prototyping
Small Business Development Centers and SCORE offer free business mentoring. Many universities run makerspaces where you can print and machine early parts for very little. Good first stop when the budget is near zero.
Website: America's SBDC
6. Design 1st and Gembah — best when you know you will manufacture
Design 1st (Ottawa, Canada) runs staged startup hardware programs. Gembah (Austin, Texas) pairs design with overseas sourcing for consumer goods. Not for you if: you need US-based manufacturing or heavy custom engineering.
Website: Design 1st
7. Local prototype and machine shops — best for a single physical part
If you have a CAD file and just want to hold the part, a print bureau or job shop is the cheapest correct answer. You do not need a development firm for that.
Frequently asked questions
What it actually costs to take an idea to market?
Run your own numbers with the prototype cost calculator , or read how to turn an idea into a product for the full sequence.
Are invention help companies legitimate?
Some are, many are not. The reliable test is what you receive for your money. Engineering deliverables, prototypes and patent filings are real. A market research packet and a promise to circulate your idea to manufacturers is the classic invention-promotion pattern the FTC has acted against repeatedly.
Should I patent before building a prototype?
Usually a provisional filing first, then build. Building often changes the mechanism, and a full application written after a working prototype describes what actually works. Any reputable firm signs an NDA before you disclose.
Is it better to license an invention or manufacture it?
Licensing needs less capital and returns roughly 3 to 5 percent of wholesale, and it works best for simple products in established categories. Manufacturing needs far more capital but keeps the margin and the brand. Most inventors underestimate how strong a prototype has to be before a licensee takes a call.
