The Higher People's Court of south China's Guangdong Province concluded the court hearing of "iPad" trademark case Wednesday afternoon without settlement after about six-hour's fierce defence. The court will pass judgement on the case another day. Both sides didn't refuse to reach a compromise while the court asked. Apple has plunged into several legal battles in China and appealed to the provincial higher court after it lost a case to Proview Shenzhen in December 2011. Proview Shenzhen and U.S. technology giant Apple have been tangled in a lengthy dispute over the rights to use the iPad trademark in China. Proview Shenzhen is a subsidiary of the Hong Kong-headquartered Proview International Holdings Limited, which also has a branch in Taipei. Proview Taipei registered the iPad trademark in a number of countries and regions as early as 2000, with Proview Shenzhen registering the trademark on the Chinese mainland in 2001. Apple bought the rights to use the trademark from Proview Taipei in February 2010 via IP Application Development Limited (IP), a company based in Britain. However, Proview Shenzhen claims it still reserves the right to use the trademark on the Chinese mainland. [Xinhua]
