Nearly one in six lawsuits received by the Shanghai Intellectual Property Court in 2015 involved an overseas party, with most claiming to be victims of trademark or patent infringement.

The accusers include luxury brands such as Burberry, Louis Vuitton and Gucci, and Fortune 500 companies such as General Electric, Hewlett-Packard and Microsoft, the court said in a report on Thursday.

The parties come from 15 countries and regions, including the United States, Germany, France, Italy, Japan, Hong Kong and Taiwan.
