>One of the most controversial issues is how the agreement affects copyright, intellectual property, and trademarking legislations. This particular section of the TPP has been a widely discussed subject in Asian countries, such as Japan, where the agreement would threaten the prosperity of amateur artist scene creating parody works on a massive scale.
A conference held by the Japanese Agency for Cultural Affairs on the 11th of November has concluded that parody works featuring characters resembling original works will not be a target for the increased anti-piracy and creator rights proposed by the main bill of the Trans-Pacific Partnership agreement. The conference council, comprised of experts on Japanese culture and copyright law, based their decision on the fact that regulating such material would not only stifle the creativity of talented amateur artists, but also negatively affect the already withering fan creation business. In essence, if the bill passed in its current state, it would hurt the entirety of the doujinshi scene, from the small-time creators to businesses based around it.
