Samsung Adds iPhone 5 to Patent Infringement Suit

Samsung made good on its promise to bring the iPhone 5 into its patent infringement fight with Apple on Monday when the electronics maker filed an amendment to a lawsuit that already included the iPhone 4 and 4S, along with the iPad 2 and Retina Display iPad.

Samsung executives said in early September that the company planned on adding the iPhone 5 to its lawsuit lineup over the smartphone's support for fast LTE wireless data networks. Apple hadn't, however, announced or confirmed the new phone existed yet.

"It's true that Samsung Electronics has decided to take immediate legal action against the Cupertino-based Apple. Countries in Europe and even the United States -- Apple's home-turf -- are our primary targets," a company executive said.

When Apple officially announced the iPhone 5 it included LTE support, just as rumors had predicted.

Samsung's lawsuit, originally filed in April, doesn't include LTE-related patents and the company isn't targeting the iPhone 5's LTE support even though executives said earlier that was an infringement concern. Instead, Samsung's April infringement lawsuit  details six utility patents and two standard essential patents.

"We have little choice but to take the steps necessary to protect our innovations and intellectual property rights," Samsung told CNET.

Apple has not commented on Samsung's new filing.
