Nokia has won a court injunction in Amsterdam that prevents HTC from using a microphone made by STMicroelectronics.
The microphone, which is part of the flagship HTC One smartphone, has apparently been developed exclusively for Nokia.
Ericsson and STMicroelectronics have announced an agreement on the future of their ST-Ericsson mobile technology joint venture.
Last year ST revealed that it wanted to leave the 50/50 partnership.
Ericsson has published fourth quarter and full-year financial results. The company made a loss of 6.3 billion Krona (£625 million) in Q4 2012, although it remained in profit for the year.
Net income for 2012 was down 53% year-on-year to £586 million, while sales were up 5% to £6.6 billion for the quarter and almost unchanged year-on-year at £22.6 billion for the full year.
Chip producer STMicroelectronics has announced a new strategic plan that’ll see it leaving the ST-Ericsson joint partnership with Ericsson.
The move is expected to be completed in autumn 2013.
