I have a great idea (a product enhancement) that I would like to get patented (my idea hasn't been patented yet) and sell my idea to get royalties off the companies. How can I go about doing this? Does anyone have any experience getting royalties from your ideas?
I'm a patent attorney. If you have any specific questions, feel free to PM them to me (or ask me here if you want). Your inquiry above is very general, and would be easier to answer over the phone unless you can narrow it down a bit. Licensing is a bit of an art. Merely having a good idea is not enough in 99.999% of all cases, even if that idea is patented. Lots of people have good ideas. Not many people turn those ideas into profitable product that someone would want to license the rights to. And irrespective of the product, getting a company to sign up for a license takes a fair amount of business savvy.
If you are serious about trying to patent your invention, don't tell ANYONE about it until you file a patent application, unless you have a confidential relationship with that person. By confidential relationship, I mean that the person is bound by some ethical or statutory rule of confidentiality (e.g., attorney client privilege), is your employee (bound by an employment agreement with relevant confidentiality provisions), or has signed a valid non-disclosure agreement.
Of course, I'm not your attorney and NOTHING I say to you or post on this forum is legal advice. You rely on anything I say at your own risk.
