I recently called an agent from a patent company and told them about an idea of mine. We signed a contract before revealing the idea and they told me that they would let me know in the following 24h if they accept to go forward with my idea.
The manager then called me and said they’re accepting, and that the first step would be to make a prototype drawing, for which I would have to pay $400. I paid, they had the drawing done but now they’re saying the next step is to license a provisional patent and show it to investors, and they’re asking me to pay $4500 for that. To me it seems a bit over the top. Please give me some advice on what I could do at this point.
