Shares in Samsung Electronics have dropped after the smartphone giant sued rival Huawei in multiple courts in China over alleged patent infringement.
They closed down 1.8% in Seoul. The country’s benchmark Kospi index wrapped the day flat at 2,010.34.
The two companies are already entangled in several legal battles over the use of proprietary technology, including fourth-generation (4G) cellular technology, operating systems and user interface software. Huawei sued Samsung in the US in May.
