Copyright in martial arts
I have a friend who is a Kung Fu intstructor with more than 30 years uninterrupted training. In 2007, after almost 28 years with the Shaolin Nam Pai Chuan Kung Fu System, he decided to leave. After a meeting, the chief instructor, Sifu Christopher Lai, agreed that he should continue to teach various forms. Initially Sifu Christopher Lai was fine with it and wished him well. However some 3.5 years later his Sifu has decided to sue him, claiming copyright infringement of the forms blah blah blah! Why did it take him so long. This sounds like bullying and a serious case of insecurity.
I wasn't aware that anyone could actually copyright the expression of human movement.. Has anybody else faced a similar problem? Please let me know.
