Nokia has filed a patent counter-suit against Qualcomm in a Texas court, seeking damages and an injunction against the U.S. chip maker.
Nokia, which makes more than one in three of the cell
phones sold globally, said on Monday it had filed a suit
accusing Qualcomm of infringing six implementation
patents in its MediaFLO mobile TV and Brew mobile data
technologies.
Qualcomm said it was disappointed, but not surprised, by
the Nokia action, which it called "standard-issue
tactics" in legal disputes such as the larger licensing
battle between them.
A legal brawl between the two firms has continued since
part of a cross-licensing deal over technology patents
expired on April 9.
Qualcomm has filed 11 patent suits against Nokia in less
than two years, seeking damages and injunctions, so far
without success. Last month Nokia filed its first
counter-suit against Qualcomm, in Wisconsin, related to
chipset technologies.
The legal dispute centers on Nokia's use of Qualcomm
patents for high-speed 3G wireless technology, but also
has a bearing on Qualcomm's chips business, which Nokia
says uses many Nokia- patented technologies.
Qualcomm has also been fighting over patents with rival
Broadcom Corp..
