LONDON Nokia and Qualcomm have extended their increasingly bitter and complex patent infringement lawsuits against each other with the Finnish phone maker filing complaints against Qualcomm in Germany and the Netherlands over the continuing validity of some of Qualcomm's IP. The move comes just weeks ahead of a deadline for the companies to renew a long standing royalties sharing agreement for W-CDMA technology.
Nokia wants the German and Dutch courts to rule on whether Qualcomm's European patents are exhausted in respect of products used in the EU market with a Qualcomm license, in this instance chipsets supplied by Texas Instruments.
Texas Instruments and Qualcomm entered into a general patent portfolio licensing deal in 2000.
Nokia says that if its claim succeeds, Qualcomm would be prevented in Europe from enforcing its respective patents in relation to Nokia handsets incorporating such chipsets.
The complaints were filed in the Regional Court of Mannheim (Germany) and in the Hague District Court in the Netherlands.
The companies are fighting hammer and tongs over renewal of a long standing arrangement on IPR sharing that is due to expire April 9.
Nokia is seeking a much lower rate for using Qualcomm's parents and has threatened to stop paying altogether if there is no agreement by the date of the expiry if the current contract. Qualcomm has said it would take legal action if Nokia carries out its threat.
