In the Spanish capital, Madrid, botanist Patrick Blanc (Patrick Blanc) once implemented in the framework of the project of green building, the idea that, by mistake, just credited to the Frenchman, not an American Stanley White Hart.

Therefore, Patrick Blanc (Patrick Blanc) has the legal right to use and update ideas from the American in the last century.
