Reports: More Chinese cities block iPad sales in trademark dispute with local company

BEIJING, China - News reports say more Chinese cities have seized iPads from retailers amid a dispute between Apple and a local company over ownership of the tablet's name.

A website of China Business News says authorities in the central city of Zhengzhou and eastern port of Qingdao seized iPads from retailers following seizures in Shijiazhuang and Xuzhou.

The Economic Observer newspaper said authorities in the eastern city of Weihai are investigating a complaint by Proview Technology that Apple is violating its rights to the iPad name.

Proview registered the iPad trademark in China in 2001. Apple bought rights to the name from a Proview affiliate. The mainland company says it still owns the name in China.

A court rejected Apple's claim to the name in China last year.
