Government officials, scholars and entrepreneurs called for stronger cross-regional administrative enforcement to tackle "evolving patent-related disputes" during a seminar organized by China Intellectual Property News that opened on April 27.

Zhang Yuegeng, deputy editor-in-chief of the newspaper, said that most Chinese companies have sharply increased their intellectual property awareness in recent years, but they still suffer from infringement that "is becoming concealed and uses various means".

He noted that multiple regions are often involved in one case, which adds complexity because of difficulties in collecting evidence, longer investigation periods, higher costs and often low compensation.
