Xiamen-headquartered touch screen maker TPK Holdings Co filed a 26.9 million yuan lawsuit against Nokia's Chinese mainland division last week claiming that one type of Nokia phone violates its patent on screen technology. At the same time it sued competitor O-film Tech from Nanjing for the same reason, asking for 60.6 million yuan in compensation. Both cases were accepted by the Xiamen intermediate court. TPK is a Taiwan-funded company and a major screen supplier for Apple's iPhone and iPad.
