Ask Patents is a question and answer site for people interested in improving and participating in the patent system. It's 100% free, no registration required.

Is there a way to track the history of this patent? It was my Great Grandfather's and we never knew he held a patent. I'm interested in learning more, such as whether he ever sold the patent/technology to a company or another person.

Welcome to ask patents -- this site is dedicated to the process and the prior art for granting patents and you question does not fall withoin thos parameters. However helpful as we are, we can only help if there is a reference to the material you question -- a patent number, name of inventor or year and title of invention -- but there is no such in the question. –  Soren Aug 26 at 12:10
