"Invention help" companies fall into three very different categories: engineering and product development firms that design and build your invention, patent attorneys and agents who protect it, and invention promotion companies that promise to market your idea to industry — and it is the third category where nearly all inventor horror stories come from. If you know which kind of help you actually need and can recognize the warning signs, you can get real value; if you cannot, you can lose thousands of dollars and years of momentum. Here is how to tell them apart.

The three kinds of invention help

1. Product development and engineering firms

These companies turn your idea into a real, working, manufacturable product: industrial design, CAD, electronics, prototype development, testing, and preparation for manufacturing. You pay for defined engineering work and you own the results — design files, prototypes, and documentation. This is the help you need if your invention exists on paper but not in physical, sellable form. What to look for in this category is covered in our guide to product engineering companies.

2. Patent professionals

Registered patent attorneys and patent agents handle searches, drafting, and filing with the USPTO. They protect the idea; they do not build or sell it. Basics worth knowing before you hire one are in our patents and intellectual property pillar and the step-by-step guide to how to patent an idea.

3. Invention promotion companies

These firms advertise heavily to first-time inventors — "we'll get your idea in front of companies!" — and charge large upfront fees for marketing packages, directories, and trade-show representation. The Federal Trade Commission has repeatedly taken action against firms in this industry, and US law (the American Inventors Protection Act) requires them to disclose their success rates precisely because those rates are historically dismal. Some legitimate licensing agents exist, but they are the exception and they rarely advertise on daytime TV.

Red flags that mean walk away

  • Instant enthusiasm. They love your idea before any technical or market evaluation. Real evaluators say "it depends" a lot.
  • Big upfront fees for vague deliverables — "marketing campaigns," "submission packages," "industry databases" — with no engineering or filing work you can hold in your hand.
  • Refusing to disclose success numbers. Promotion firms must tell you how many clients made more money than they paid. If the answer is evasive, the answer is the answer.
  • Pressure tactics. Countdown discounts and "someone else will patent it first" urgency are sales scripts, not advice.
  • Owning your IP. Any contract that assigns them rights to your invention in exchange for "free" help deserves a lawyer's review before signing.
  • No named engineers or verifiable work. A real development firm can show a portfolio of shipped projects and tell you exactly who will work on yours.

How to vet any invention help company

Ask five questions: What exactly do I receive, and when? Who owns the design files and IP when we are done (the answer must be: you)? Can I see comparable projects you have completed? How is pricing structured — fixed milestones or open-ended hours? And what happens if the evaluation says my idea is not viable? Honest firms sometimes talk inventors out of spending money; promotion mills never do. Cross-check reviews, check for FTC or state attorney general actions, and get every promise in writing. Our first-time inventor guide covers the wider journey these companies fit into.

Match the helper to your stage

If you are still at the raw-idea stage, start with the sequence in I have an invention idea — now what? — validation and protection come before any big spend. If the idea is validated and needs to become a physical product, you want an engineering firm. If it is built and protected and you want a licensing deal, study selling your invention before paying anyone to pitch it for you — most successful licensing deals are closed by inventors themselves with a strong prototype and sell sheet.

Talk to engineers, not salespeople

Projects House is an engineering firm: we develop inventions into working, manufacturable products, you own everything we produce, and pricing is fixed per milestone before work starts. If you want an honest technical assessment of your invention — including whether it is worth developing at all — write to us through the contact form. The conversation is confidential and costs nothing.
