I would think it would depend on the year. When he first invented it, probably him. Later on when he was selling the things, not. Edison was obsessed with making money from the patents he had, applying them to anybody making movies; the reason Hollywood (the industry) is in LA is that filmmakers fled the East Coast to the wild west to get away from Edison's lawsuits. so perhaps (speculating) if Edison was spending a lot of time with lawyers, I tend to doubt he was doing the filming. Mark Twain was a celebrity though, so perhaps it was a friendly visit.
