Taiwan based touchscreen manufacturer TPK Holding has sued Nokia and Huawei in China over a patent covering its display screen technologies.

TPK said that its Chinese mainland subsidiary has filed two lawsuits in the Xiamen City Intermediate People's Court of Fujian Province against Nokia, Huawei and other companies that it said have infringed upon its "single-sided indium tin oxide" technology, for which it holds a patent in China.

Chung Chi-li, a TPK executive, said the technology allows manufacturers to produce thinner touch panels.

One lawsuit was filed against Nokia's Lumia 610 smartphone assembler Compal Communications, while another was filed against O-film Tech which makes panels for Huawei's C8812E handset.

TPK said it is seeking damages of RMB26.91 million (USD4.3 million) from Nokia, and RMB66 million from Huawei.
