Nokia is trying to 'compensate for its own failing cell phone business'

Apple on Tuesday filed an antitrust lawsuit against Acacia Research Corporation and Conversant Intellectual Property Management, alleging that the two "patent assertion entities" have colluded with Nokia "to extract and extort exorbitant revenues unfairly and anticompetitively from Apple" and other companies.

The lawsuit comes a week after Apple was ordered to pay Conversant subsidiary Core Wireless Licensing $7.3m for infringing on two mobile communications patents.

According to the complaint, Acacia and its subsidiaries have sued Apple more than 40 times in the US and abroad, while Conversant and its subsidiaries have sued Apple more than two dozen times.

At least a dozen of these patent infringement claims have been based on Nokia patents.

Apple has made its own patent claims against supposed infringers.
