In the patent infringement between Apple and Samsung, District Court Judge Paul S. Grewal has granted Samsung's motion to add the iPhone 5 to Samsung's list of allegedly infringing Apple products.

Apple started the lawsuit with Samsung by alleging that Samsung infringed several Apple patents.  Samsung replied, in part, by counter-suing Apple for alleged infringement by Apple's iPhone and iPad products.  Apple is also involved in patent infringement litigation against Google.
