Romek Figa [NPE/Inventor] filed suit against Sony Ericsson and AT&T over a patent related to telephone caller identification display system. 3/4, 1:2011cv10379. Figa has filed three previous suits to date. Romek Figa has successfully licensed the patent to Motorola, Nokia, and Samsung, and then settled with VTech during a suit in 2007.  He has also filed suit against HTC and Apple over the same patent.  In the Apple case, Apple was determined to have not infringed, but their motion to invalidate the patent was denied.  Apple had tried to argue that the patent was invalid because it did not provide the algorithm which is needed to relate a caller to a contact in the phone.  The judge denied this claim and saying that Apple failed to prove that the algorithm would not be apparent to a person skilled in the art. The HTC case is still pending.
