Yes bryan. Inventors principally discover new knowledge by research. Innovators apply the knowledge by building technology. People like Nikola Tesla traded in patents as do the people in this wiki. Dr Kia Silverbrooke actually has a patents business called Priority Matters. Tom Edison was a good mix of both - General Electric was an idea and product factory - same as most renaissance men. The robber barons were ruthless industrialists - Edison's bareknuckle business tactics earned him many foes. Elon Musk is an innovator (not an inventor) - as were Gates, Jobs, etc - who were accused of various anti-trust breaches. I believe Elon Musk's SpaceX will eventually be declared a monopoly - which means he'll be guilty of excellence - as his solutions overwhelm the competition.
