China Supreme People's Court (SPC) recently released its proposal for public comments titled Interpretations of the Supreme People's Court on Certain Issues Concerning the Application of Law in the Trial of Patent Infringement Cases II. It is a further development of the SPC's judicial interpretation on the trial of patent infringement cases. The first part of the interpretation has been implemented since January 1 2010, and has been an important source of authority for lower courts to deal with patent infringement cases. This second part covers more aspects of patent litigation and could have a significant impact on patent litigation practice.
