You people are a bit late to the patent raping of India...

And you know what? There's jack-all that the common person can do about it, apart from signing petitions to let the concerned people know how you think they are bad guys and maybe make them feel a bit guilty.
The only way India can fight these things is through appealing to the judicial body concerned and filing for a patent on the grounds of this being indigenous knowledge. Furthermore, we should demonstrate that there is no way this Baba Ramdev dude came up with Yoga in the first place.
Having said that, India should also immediately patent all these things if they want to protect this kind of problem in the future, and allow their use without having to pay royalties. But knowing India...none of this is going to happen. After all, the west has been raping India even after Independence.
