Shanghai Old-Town Temple Restaurant (Group) Co and Shanghai Nanxiang Food Co are suing each other alleging trademark infringement related to xiaolongbao(steamed dumplings) and illicit competition.

The Pudong New Area’s court andYangpuDistrict’s court have accepted their complaints. ThePudongcourt said on Wednesday that a hearing had been set for September.

The temple restaurant company and its subsidiaryNanxiangsteam buns company are asking theNanxiangfood company, and two related companies, to stop using the “Nanxiang” trademark and pay 3 million yuan (US$432,000) compensation,according to the Pudongcourt.

The old-town temple restaurant said it registered the “Nanxiang” trademark for the restaurant category in 1994.

In 2014, theNanxiangfood company opened a number of restaurants. some of which use the name “Nangxiang” and print it on posters, menus and tableware, the old-town temple restaurant company said.
