In a search for a specific tool, I found a patent describing exactly what I need. However, I couldn't find any tool on the market using the technology it describes. What can I do?
- Is there a way to contact the patent holder and ask him if he used it for commercial purposes, and if so, where/how?
- I though if the product doesn't exist on the market, I could produce it on my own, giving royalites to the beneficial owner. But does a patent holder have the right to not use it at all and forbid anyone else to do so?
