As promised, Samsung has filed a lawsuit against Apple's iPhone 5. In a statement cited by Reuters, Samsung said, "we have little choice but to take the steps necessary to protect our innovations and intellectual property rights."
Samsung alerted the United States District Court for the Northern District of California in September that it would seek to include the iPhone 5 in its allegations of patent infringement against Apple. Samsung formally filed this request with the court on Monday, October 1. In its request, Samsung argues that the iPhone 5 should be included in its current case because the smartphone "has the same accused functionality as the previously accused versions of the iPhone."
This court case is the second legal battle between Apple and Samsung and was filed in early 2012. It is slated to go to trial in March 2014. Judge Lucy Koh, who presided over the first lawsuit, is also presiding over this second case. The first lawsuit is in the post-trial stage now that Samsung has been found guilty of infringement.
