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?

  1. Is there a way to contact the patent holder and ask him if he used it for commercial purposes, and if so, where/how?
  2. 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?

Search through the file history using USPTO PAIR to find out inventor information. Search patent assignments using USPTO assignment search to find out owner information.

But does a patent holder have the right to not use it at all and forbid anyone else to do so?

Yes, of course. Many patents describe technology that is never used. A patent owner does not "forbid" others from using patented technology. The patent owner may sue others for alleged infringement.
