Today TPP chapter regarding to Intellectual Property Rights was leaked by Wikileaks [1] and seems to be very dangerous. As Chilean NGO Derechos Digitales has pointed [2] some clauses as the named "Appropiate Balance in Copyright and Related Rights Systems", that can force to the signatory countries to make changes into their own Right Laws to have more restrictions.
