Summary Box: Reports of iPad seizures in China

THE DISPUTE ESCALATES: News reports say authorities have seized iPads from retailers in more Chinese cities as Apple Inc. and a struggling local company squabble over the trademark for the popular tablet computer.

WHERE: IPads were seized in Zhengzhou and Qingdao, a website run by newspaper China Business News said. Seizures were reported earlier in Shijiazhuang and Xuzhou.

COURT BATTLE: Apple bought rights to the name from a Taiwan company affiliated with Shenzhen Proview Technology, but the mainland company says it still owns the name in China. Apple is appealing a Chinese court’s rejection of Apple’s claim to the name.
