As an American and a Yogi I have to say America has to be the only country where "entrepreneurial" teachers of Yoga feel the right to patent Yoga.
Exactly when Yoga started is a matter of debate but most will grant it a couple of thousand years at least and most much farther back.
As an example is [Forrest Yoga](http://www.forrestyoga.com/) where prior art is technically in illustratiosn and text in ancient books. (There are diligent engineers in India working to scan every single page of these books as so people can claim it as prior art.
In Forrest yoga though they have made slight different in some of the poses to justify it.
More importantly its the morality of feeling like as a teacher with maybe 40 years or less experience that you have mastered Yoga enough to own it.
So, now in the US there is a lot of money in Yoga, and Americans at every level are trying to create patents to
protect their "business" Be it in Yoga itself, in the teaching of Yoga, in the franchises, and apparently the filming of Yoga.
I feel we need a rule that will punish an organization or person filing or a patent that is objectively illegitimate.
I suppose the punishment would have to be based on a percentage of the gross earnings of the company.
