Accurately speaking, Proview Group registered the trademark of ipad around 200 1. When Apple was preparing to launch the ipad, it learned this and found Proview to purchase the right to use the trademark. But at that time, Apple was looking for Proview's Taipei branch, but the Taipei branch only had the trademark right except Chinese mainland, and the mainland trademark right was in the hands of Shenzhen branch. In other words, Apple did not buy the right to use the trademark in mainland China at first, so the sales in mainland China constitute infringement. However, the purpose of Proview is only to make money from Apple, and the actual impact on Apple will not be great.
