Commercial Press
In 2016, The Commercial Press (Beijing) filed a lawsuit at Beijing intellectual property court, claiming Sinolingua Co., Ltd. had violated The Commercial Press's trademark for Xinhua Zidian by publishing "Xinhua Zidian" without permission from The Commercial Press, even though the trademark name was not registered. The original case started when 3.2 million copies of student edition of Xinhua Zidian (学生新华字典) published by a company in Hubei were recalled for poor quality.
