Most courts in Taiwan have denied legal redress in infringement suits to holders of copyrights on immoral or obscene works by applying judicially-created doctrines. These judgments were based on the Supreme Court held that adult films are not copyrightable because these films are against social order or public interest, and in no way promoted social development in 1999. However, the Taiwan Intellectual Property Office ("TIPO") has tended to recognize porn films as copyrightable works. In an administrative letter of explanation issued in 2008 (Zhi-Zhu-Zi No. 09700025950), TIPO stated that if adult films are original, they are covered by copyright regardless of whether they are also categorized as obscene material. Porn isn't an object of copyright protection until the IP Court in 2014 held that a pornographic work is entitled to copyright protection as long as it meets the originality requirement. Contrary to individual opinions in Taiwan, porn is taken it for granted that AV can be protected under Copyright Act in Japan.
