Nokia has been ordered by a US court to pay up to £150m to InterDigital Communications, after losing a wireless patent dispute case.
The demand was made by a US district court after a long-running battle between the two companies. InterDigital says Nokia owes it royalties for using patented 2G and 2.5G technologies.
Last June, the International Chamber of Commerce said Nokia should pay the royalties InterDigital had claimed, but Nokia had disputed the amount.
Nokia has not yet responded to the latest ruling. InterDigital said that if Nokia still refused to pay it would take further legal action against the world’s biggest mobile handset company.
The pair had signed a technology licensing agreement in 1999.
