Lawyers for Apple and Proview exchanged heated words today in a Shanghai court hearing, according to reports from the Associated Press and Reuters. Proview is seeking a ban on iPad sales in the city as a part of its ongoing trademark dispute with Apple. "Apple has no right to sell iPads under that name," said a lawyer for Proview Shenzhen, Xie Xianghui. Proview once sold a product called the IPAD, or Internet Personal Access Device.
