This payment of $20 Million is just covering license fees for Q2 2007. Nokia and Qualcomm continue to push their heads together for a long-term patent cross licensing agreement.

This sums are considerable, and worth fighting over to protect your bottom line.
"As we continue to negotiate the new cross-license agreement, Nokia views this payment as fair and reasonable compensation for the use of relevant Qualcomm essential patents in Nokia UMTS handsets during the second quarter of 2007. Nokia believes that Qualcomm's patent portfolio is concentrated in the United States, and that it has few or no alleged UMTS patents in many of the countries in which Nokia has substantial UMTS handset sales. When Qualcomm's early patents become paid-up and royalty-free on April 9, 2007 Qualcomm's share of all patents relevant to Nokia UMTS handsets will significantly decrease", said Rick Simonson, chief financial officer, Nokia.
