iPads seized in copyright row

More Chinese cities have seized iPads from retailers in a dispute between Apple and a local company over ownership of the tablet's name.

Authorities in the central city of Zhengzhou and eastern port of Qingdao seized iPads from shops following seizures in Shijiazhuang and Xuzhou.

In the eastern city of Weihai, authorities 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, but the mainland company says it still owns the name in China.

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