I have ideas about how to improve an existing product that will save buyers and users of the product lots of time and it will also improve the quality of use of the product and expand the use of the product. The product is owned by an existing company and for sure has a patent already. I want to present my ideas to the company but would like to participate in the financial gain the company receives by using my ideas. How can I protect my ideas and share them with the company at the same time?
