Apple has filed a countersuit against Nokia over the alleged infringements of ten technological patents.

US electronics company Apple has filed a countersuit against Finnish telecoms firm Nokia over alleged infringements on patents.

In October this year, Nokia filed a complaint against Apple for its ten alleged infringements on Nokia patents for GSM, UMTS and wireless LAN (WLAN) standards.

Apple has now filed a countersuit, claiming that Nokia is infringing on 13 Apple patents.

Bruce Sewell, Apple’s General Counsel and Senior Vice President, said: “Other companies must compete with us by inventing their own technologies, not just by stealing ours.”

Nokia claimed that the Apple iPhone infringed on technological patents including patents covering wireless data, speech coding, security and encryption.

When the complaint was first filed, Vice President of Legal and Intellectual Property at Nokia, Ilkka Rahnasto, said: “The basic principle in the mobile industry is that those companies who contribute in technology development to establish standards create intellectual property, which others then need to compensate for.

“Apple is also expected to follow this principle. By refusing to agree appropriate terms for Nokia’s intellectual property, Apple is attempting to get a free ride on the back of Nokia’s innovation.”

Apple has not yet specified which patents the countersuit covers.
