As expected, Samsung has added the iPhone 5 to their platter of existing lawsuits against Apple. "Apple continues to take aggressive legal measures that will limit market competition," said Samsung in a prepared statement. "Under these circumstances, we have little choice but to take the steps necessary to protect our innovations and intellectual property rights," says the company. Samsung owns about 12% of the 3,000 existing LTE patents (Nokia owns 18.9% and Qualcomm owns 12.2%), and the lawsuit revisions will likely primarily focus on LTE. While Samsung recently lost a $1 billion court ruling in the States, their battle with Apple is global, the companies engaged in fifty different patent disputes in ten different countries.
