Crystal materials maker Tera Xtal Technology Corp filed a lawsuit in Taipei against Apple Inc, claiming that the US electronics giant used its patent on sapphire crystal without authorization. The company said that Apple used the technology to incorporate sapphire into camera lenses in the iPhone series. It also sued two local handset retailers because they sell iPhones in Taiwan. Tera Xtal sought total patent infringement damages of $9.88 million.
