An invention can have monetary value because it creates a new (profitable) market where one did not exist before (e.g., the photocopier, the browser, etc.), because it conserves a limited resource or reduces product inputs, because it reduces the cost of an existing product or process, or because it reduces the cost of living, etcetera. Sometimes it is difficult for others to see how manufacturing a particular invention would produce more income than it cost (i.e., produce a profit). Why is your invention likely to be valuable? What is the approximate size of its market in dollars per year?
If you have prepared an economic analysis of the cost of producing a product that incorporates your invention versus the income it would produce, present it here. If not, explain why you think someone selling your invention would make money. (Skip a line between paragraphs and indent the first line of each paragraph.)
