Qualcomm is suing Nokia in the UK for allegedly infringing two of its patents covering GSM and 2.5G mobile technology.
The action is an extension of Qualcomm’s ongoing action against Nokia in the US, covering alleged abuses of the same patents.
The alleged infringement covers mobile devices which are capable of operating in accordance with the GPRS and/or EDGE standards.
The action does not cover standards supporting 3G technology. Qualcomm is a leading developer of 3G technologies using its chipsets, which comply mainly with the CDMA standard.
Nokia mainly relies on using the W-CDMA 3G standard for markets in Europe and elsewhere.
Qualcomm first took action against Nokia in the US last November. Nokia has not responded so far to the action being taken in the UK. It is defending the action in the US.
