In response to Nokia's own claims of copyright violation, Apple on Friday accused the largest handset maker in the world of copying some of the technology inside the iPhone.
According to a Reuters report, the countersuit heats up the fight between the two companies. While relative newcomer Apple trails Nokia in cellphone shipments, its iPhone has been gaining a lot of ground against the market leader in the smartphone segment.
In court documents, Apple denied infringing the Nokia patents and said that the patents asserted by Nokia were not essential for technology standards used in cellphones. It said the countersuit was filed in the same Delaware court where Nokia brought its case.
Apple is also asking the court to dismiss Nokia's suit, and goes so far as to accuse Nokia of borrowing some of Apple's intellectual property because it was losing market share.
Apple also said that Nokia had engaged in anti-competitive behavior and did not live up to commitments to license its own technology at fair and reasonable terms, Reuters reported.
