The book focuses the openness of Chinese copyright law and patent law, namely the right limitation and exception rules (as the IP-internal balancing mechanism) and the right enforcement and protection (as the IP-external balancing mechanism). It examines the highlights of the 3rd and 4th amendments to the Chinese copyright law, patent law and the trademark law, addressing the most debated questions during these amendments. This book also takes a comparative approach to study the legislations and case laws in the USA, EU and China. The comparison covers the legislation, case decisions, which could offer useful clues for legislators to revise the current law, for judges to decide the cases about relevant topics and lay down their market plans. Moreover, this study also provides several recommendations for the right holders who are currently operating or planning to operate in China, regarding the de facto protection levels of their IP rights, the risks of right infringement and litigation costs as well as the trend of the goalsetting in their intellectual property strategy.
