Identify the service behind the promise
A promoter may offer research, patent assistance, prototype development, introductions or licensing support. Those are different services with different deliverables. A package described as “taking your invention to market” is not specific enough to compare or accept. Ask what files, reports or completed actions you will receive and what is expressly excluded.
Write the proposed engagement in plain language. If you cannot explain what the first payment buys, you are not ready to authorize it. Distinguish a list of potential companies from an introduction, an introduction from a negotiation and a negotiation from a signed agreement. Sales language often blurs these milestones.
Request evidence before evaluating the sales pitch
The FTC's invention-marketing guidance explains that federal law provides rights to certain information about a promoter's operations and clients before a contract is signed. Review the current official list and request the relevant disclosures in writing. Do not accept a success percentage without its definition, time period and denominator.
Check references independently and ask about the work delivered, additional costs and actual outcomes. A reference who enjoyed the representative's communication may still have received no commercially useful work. Ask whether the client would buy that specific service again and what they would change.
Search complaints and official enforcement information, while recognizing that a complaint is not itself a proven finding and the absence of complaints is not proof of quality. Preserve a copy of the proposal and important claims rather than relying on a changing webpage.
Separate legal representation from promotion
If patent work is included, ask who performs it and who represents you. Verify the practitioner through the USPTO's official resources and understand the engagement relationship. A marketing company being well presented does not establish that its staff may represent you before the patent office.
Clarify who owns the files, who receives official correspondence, what deadlines are included and how you obtain the complete record if the relationship ends. Do not hand over passwords as a substitute for a proper representation arrangement. Obtain independent legal review when the proposed contract affects rights or involves a significant commitment.
A worked comparison of two hypothetical offers
Offer A costs $4,000 and promises “industry exposure,” a market report and patent support. Offer B costs $1,200 for a defined search report with named databases, documented queries, identified results and a review meeting. These amounts are hypothetical and are not market-rate estimates.
The smaller price is not automatically the better choice. The difference is that Offer B can be assessed against a concrete deliverable. Offer A requires more questions: what exposure, to whom, how many contacts, what patent support and what later payments? If answers remain vague, a comparison by price is meaningless.
A sensible next step could be a limited engagement with acceptance criteria and a clear right to obtain the resulting files. The decision should follow evidence about competence and scope, not the emotional appeal of someone praising the idea.
Review the whole payment path
Ask for the total expected cost and the conditions under which additional fees appear. A low entry fee can lead to an expensive second stage after the inventor feels committed. Record whether services are optional, which charges are refundable and what happens when a milestone is not achieved.
Have a qualified adviser review significant contract provisions, including ownership, exclusivity, dispute terms and termination. Do not treat a provider's assurance that “everyone signs this” as an explanation. Keep your own copy of the executed agreement and payment records.
Use a pause rule for high-pressure sales: no same-call commitment to a material payment. A legitimate deadline should have an understandable reason that can be checked. A salesperson's calendar is not evidence that your invention has a unique opportunity that disappears tonight.
If you have already paid
Collect the contract, receipts, promised deliverables and communications. Compare completed work against the agreement without embellishing the record. Ask a suitable legal or consumer-assistance professional about options based on the facts and payment method.
The FTC and USPTO provide reporting routes for suspected invention-promotion problems. USPTO's complaint forum publishes complaints and responses; it does not mean the office has investigated or recovered funds for you. Follow the current instructions rather than assuming a report is a refund request.
A useful provider leaves you with understandable work and evidence you can use elsewhere. If the main thing you receive is continued enthusiasm followed by another invoice, stop and reassess before increasing your exposure. This is a due-diligence method, not a finding about any named company.
