US Chipmaker Qualcomm is attempting to strike a devastating blow to Apple's operations, with a lawsuit seeking to ban the manufacture and sale of the iPhone in China.
The San Diego-based company aims to inflict pain on Apple in the world's largest market for smartphones and cut off production in a country where most iPhones are made. In the most recent development, Qualcomm is now filing a lawsuit against Apple with the intent of having all iPhone production and sales halted in China. Qualcomm previously requested an iPhone ban in the United States.
Qualcomm says the patents cover power management and a Force Touch technology used in current iPhones. Talking about these patents, Trimble says they are "examples of the many Qualcomm technologies that Apple uses to improve its devices and increase its profits".
Qualcomm alleges that Apple is using technologies invented by Qualcomm without paying for them. As a result the firm's shares are down nearly 20 per cent.
