17.If a famous foreign book has passed its protection period and a film company exploits its IP,does it constitute an infringement?

The written work has entered the public domain if it is judged to be expired according to applicable law (for the protection period of copyright under Chinese law, see section V of this chapter).If one wants to use the original content in such a work, it is legal from the perspective of Copyright Law.However, if the content of a published Chinese translation is used in the narrative, the copyright of the translator will also be involved.According to the Copyright Law, the copyright of a work of translation shall be enjoyed by the translator, but the translator shall not infringe upon the copyright of the original work when performing his or her copyright.The term of protection for a translated work is also the lifetime of the translator plus 50 years after his or her death.In addition, if one wants to use the name of a masterpiece, trademark rights may be involved.The same or similar name should be checked against the work’s planned name in order to avoid trademark infringement.(https://www.daowen.com)
