According to Haidian District people's court, JD.Com accused Tmall.Com, which is under Alibaba of exaggeration on some outdoor and newspaper advertisements in September that promised same-day delivery in Beijing.
Actually, only residents in certain parts of the city are able to enjoy the service, and only on items ordered before a certain time of the day.
Many people still have to wait until the next day to get their packages, said JD.Com, state-run Xinhua news agency reported.
JD.Com asked the defendant to stop posting the ads and release a statement admitting they had been deceptive.
Alibaba has not made any comment on the issue so far.
The petition came ahead of November 11 Singles' Day sales on e-commerce platforms in China.
Last year Alibaba reported USD 10 billion sales on that day while JD.Com reported 14 million sales.
