Q: How can I contact the assignee or inventor of a patent?
A: First you need to check if the patent has been assigned or not.
If the patent has not been assigned, then you can contact the inventors listed on that patent.
If the patent has been assigned, you should contact the assignee only because inventor(s) don't have legal rights in this patent anymore.
Both, the inventors information and assignment information is available at the USPTO web site.
