After failing to strike a new deal, Nokia is suing Apple for patent infringement

After failing to strike a new deal with Apple, Nokia is suing the iPhone maker for patent infringement in both Germany and the US. The two companies had a deal in 2011 that covered some Nokia patents, but Nokia says efforts to reach a broader pact have gone nowhere. “Nokia has created or contributed to many of the fundamental technologies used in today's mobile devices, including Apple products,” Nokia patent head Ilkka Rahnasto said in a statement. “After several years of negotiations trying to reach an agreement to cover Apple's use of these patents, we are now taking action to defend our rights."

One of the big concerns in the phone industry has been just how agressive Nokia might be in pursuing large patent claims now that it is no longer in the phone-making business. (New phones are being introduced under the Nokia brand, but through a brand licensing deal, not because Nokia itself is selling phones.) Nokia’s remaining business is largely focused on making network equipment, though its smaller Nokia Technologies unit has a mission to both innovate in new areas and license the company’s brand and vast patent portfolio.
