A technical background.
A practical approach to patent law.
I’m a registered patent attorney and the editor behind Patent Law Joe. My background spans patent litigation, examining inventions at the USPTO, and technical service in the U.S. Navy.

Patent law, from more than one side.
Legal practice, patent examination, and technical training are different ways of looking at an invention. Each is part of the experience I bring to this site.
Since 2021
Working with patents in practice.
