Your initial pitch to potential partners should be short and to the point. It should be concise but professional, and do we have to say grammatically correct and error free. Focus on the problem and the benefits of using your invention as the solution. Focus on the advantages and leave the door open for questions.
Great performers always leave their audiences wanting more, and you should be no different. It is much better to engage a potential investor or partner by answering their questions than to give them a full blown power point presentation with all the answers (from your perspective) and getting the polite nod. The polite nod usually means no, not interested, have a nice life. It is the deathblow to selling invention ideas, at least to that potential investor or partner.
Communicate your vision of sales and distribution, but leave the door open for the experts to tell you what they think. Your partners, whether they are investors, manufacturers or distributors may know your target customers a lot better than you do. You can kill the deal by not being open to their input. Every successful new invention is the result of teamwork. Your new invention is no exception.
Finally, be reasonable with your expectations. Investors, manufacturers and distributors all have to get their cut. We will never know how many inventions never made it to market because the inventor wanted all the money for their ideas as described in this article on https://goodmenproject.com/featured-content/let-inventhelp-turn-your-invention-into-a-commercial-success/.
Greed has killed more opportunities than it has created. It has caused more pain and suffering than it has relieved. Greed can leave your invention on the shelf in your garage and keep you from selling invention ideas. Share the wealth, have reasonable royalty or revenue sharing expectations and you can expect to have some success. Being greedy will kill the goose that could lay the golden eggs.
Follow these guidelines to turn your idea into revenue. Of course there are thousands of minute details that you must take care of but these are the key concepts to selling invention ideas.
