The iPhone maker, Apple Inc., has accused Nokia Oyj, in official court documents, of trying to "monopolize" the market as far as the wireless technology segment goes.

Apple, in a federal court filing yesterday in Wilmington, Delaware, stressed that Nokia had, on purpose, withheld complete information on its patent holdings while it was assisting the establishment of an industry standard, and then ended up asking for "unreasonable" royalties.

"Nokia deliberately and deceptively failed to disclose in a timely manner (its intellectual property rights). This course of misconduct enabled Nokia to obtain monopoly powers (in each of five areas) to obtain excessive royalties”, Apple accused in the filing.

The fierce legal battle between Nokia and Apple began in October of last year, when Nokia, the biggest manufacturer of mobile handsets, filed a lawsuit against Apple, alleging that the technology giant had infringed as many as
10 of its patents, and demanded royalties on over 42 million iPhones, sold since the device's launch in 2007.

"Having suffered losses in the marketplace, Nokia has resorted to demanding exorbitant royalties from Apple for patents that Nokia claims are essential to various compatibility standards", said Apple in yesterday's filing.
