Besides the reports that Nokia’s sales decreased, the mobile phone manufacturer is about to lose yet another case. After agreeing to a settlement months ago, Nokia is said to pay Qualcomm over $2.3 billion as a result of the lawsuit filed by the latter against the former.

The lawsuit began after Nokia used Qualcomm’s chipsets in their 3G devices without Qualcomm’s official go-signal. But over the second quarter of the year, Nokia and Qualcomm entered into a 15-year agreement premitting Nokia to use Qualcomm’s chips after undergoing the necessary licensing procedure.

For the case, Qualcomm is demanding for the settlement in lump sum.
