Apple is at the center of 60 per cent of the patent lawsuits in the mobile industry according to according to intellectual-property consulting firm Kanzatec IP Group.
Kanzatec has published an infographic showing who is suing who. You can view a larger version of the graphic, here.
In the best-known cases Apple has filed suits against Samsung, Motorola, HTC, and Kodak. In all those cases Apple is being counter sued by the party.
There have also been suits filed against Apple in which Apple isn’t countersuing: Nokia and Elan.
Kanzatec senior vice president Feisal Mosleh said: “I would speculate that Apple will continue to be at the center of the litigation map of large mobile IT companies for as long as it maintains its dominant place in the market.”

Nokia v Apple
Nokia first sued Apple in Delaware District Court back in October 2009, laying claims that the iPhone violated ten different patents owned by the Finnish cell phone company. In June 2011 Nokia and Apple settled the almost two-year long legal battle over patents with an agreement that will see Apple pay a lump sum and ongoing royalties to the European mobile-phone maker.
Recent reports suggested that Nokia has made more income from licensing patents used in the iPhone than selling its Windows Phone-based Lumia devices.

Elan v Apple
Elan sued Apple way back in April of 2009, alleging that Cupertino had infringed upon two of its U.S. patents covering touch-based technologies. That suit requested that the U.S. government prevent Apple from building or selling iPhones, iPod touches, and MacBooks.
News that Apple had paid out $5 million as part of a settlement to the Taiwanese company came in January 2012.
Bloomberg speculates that with its growing global market share and huge amount of cash on hand for possible settlements, Apple is becoming a bigger and more attractive target for patent holders.
