After a patent dispute between Nokia and Blackberry's parent, Research In Motion (RIM) over common type of wi-fi connectivity that RIM uses in all their devices and Nokia has a patent for, Nokia had asked the courts in the US, UK and Canada to block sales of rival Blackberry smartphones.
If Nokia succeeded in their ruling RIM will not be allowed to produce devices that offer this type of wi-fi connectivity until it agrees to pay license fees.
RIM has said: "Research In Motion has worked hard to develop its leading-edge Blackberry technology and has built an industry-leading intellectual property portfolio of its own " - a possible signal that it might counter sue, and they said that an earlier licensing deal with Nokia meant it should not have to pay a separate fee for the technologies. However, the tribunal disagreed.
Nokia has separate case against RIM in Germany involving antenna, email and navigation technologies. And the company had licensed its intellectual property rights to more than 40 other companies. The revenue from such deals helps justify its current $11.8bn market valuation.
