With more frequent economic and trade exchanges between China and the world, IP disputes involving foreign litigants nationwide rose from 2,840 in 2013 to 5,675 in 2015.

Of the IP administrative cases involving foreigners, most were related to patents and trademarks, while those involving business secrets have also risen rapidly in recent years, according to Song Xiaoming, the chief judge of a civil tribunal for IP cases under the Supreme People's Court.

A report by IP House, a third-party IP institute that analyzed 5,022 verdicts from 5,432 IP cases heard by the Beijing IP Court recently, found that 1,095 were related to foreign litigants. Of the foreign cases, 395 involved US enterprises, 2.7 times more than those from Germany, which was second on the list, the institute said.
