From the HongKong court findings :
Yang Long San, Rowell (Yang), a Taiwanese, is the founder of the Proview Group. He was at all material times the chairman and chief executive officer of Proview Holdings until he was adjudicated bankrupt on 2 August 2010. Other companies of the Proview Group that feature in these proceedings are Proview Electronics, a Taiwan company, Proview Shenzhen and Yoke Technology, both being Shenzhen companies. Yang was at all material times the responsible person and director of Proview Electronics. He was also the legal representative, general manager and chairman of both Proview Shenzhen and Yoke Technology and remains so despite his bankruptcy.
. . . the Written Agreement and the Country Assignments executed on 23 December 2009 expressly stated that Proview Electronics was the proprietor of the Subject Trademarks including the China Trademarks and that Proview Electronics warranted that it was the unencumbered sole owner of the Subject Trademarks including the China Trademarks. The Country Assignment pertaining to the China Trademarks (the China Country Assignment) also recited that Proview Electronics was the proprietor of the China Trademarks. However, after Apple had announced the launch of iPads in January 2010, it was discovered that the China Trademarks were in fact registered in the name of Proview Shenzhen. The China Country Assignment was accordingly ineffective in assigning the China Trademarks to IP Application.
10. Apple and IP Application further complained that while acknowledging that a mistake had been made in the China Country Assignment, the Contracting Defendants refused to rectify the mistake and suggested that Apple should pay US$10 million to purchase the China Trademarks.
Summary :
1. Apple, as B&M holdings purchased iPad trademark from Proview, including all rights in China, Taiwan and HongKong.
2. The parent company Proview clearly stated they own the rights to all the Trademarks.
3. Yang was legal representative, general manager and chairman for Proview Taiwan, Proview Shenzen, and Yoke. In other words, he as the authority to sell the company assets.
4. On December 23rd 2009 Yang sells the trademark to "Apple" for 35,000 pounds.
5. Apple announces "iPad" in January 2010.
6. It is discovered that Proview Shenzen owns the Trademark (Yang is the Chairman)
7. March 2010, Proview Shenzen asks for $10,000,000 for the trademark.
8. Apple refuses and has been fighting since then to gain control of the trademark that they already purchased.
There should be no case here, Proview lied, and deceived B&M until Apple announced their product and then tried to extort money. It seems obvious that Yang saw that B&M was Apple, settled for any money with the intent to extort money later.
