I recently listened to a podcast on how the founder of Bikram yoga was claiming that his method of yoga was "his" and that anyone who taught that style needed his permission. I've experienced this in the martial arts. When I trained in Soo Bahk Do, their Federation contended that all of their material was the Grandmasters property and they were willing to sue anyone who taught it without their permission. What do you think about the idea of intellectual property as it applies to martial arts? Can you own a technique or method? What would you classify as intellectual property?
