As promised last month, Samsung filed suit against Apple this evening for what it perceived to be patent infringements in the iPhone 5.

Apple previously won a $1 billion judgment against Samsung from patent infringements, and it plans to add more of Samsung’s newer devices to the list from which it seeks damages. The Samsung’s suit announced today will go to trial sometime in 2014.. this is definitely far from over.

In a statement, Samsung said: “…we have little choice but to take the steps necessary to protect our innovations and intellectual property rights.”
