A new judicial interpretation on patent disputes was published on Tuesday, aimed at providing better protection for innovators and improving technological developments in China, officials of the national top court said.

Effective from April 1, the interpretation is an updated and revised version of one also issued by the Supreme People's Court in 2009, Song Xiaoming, chief judge of the No 3 Civil Tribunal under the top court, told a news conference.

The top court decided to update the interpretation due to the increasing number of patent disputes over the past five years and the pace of technological development, according to Song.

Wang Chuang, deputy chief judge of the tribunal, said that the new interpretation will provide more legal protection for innovators.

It will also address a major complaint in previous patent disputes, that it was hard to collect evidence and lower compensation, Wang added.
