Samsung and Apple are in a steep court battle right now over claims that one infringed upon the patents of the other when making their popular smartphones. Samsung is trying to defend itself from having to pay Apple $2 billion.

The fight intensified this week when Samsung demanded $6 million from Apple for FaceTime, Apple's video call feature, that Samsung says infringes on its video call patents. Specifically, Samsung says its patent is for the compression of video before it's sent over a mobile network, and the company demonstrated how FaceTime does just that.

Apple is trying to get $40 for every device Samsung sold that they say infringes on their patents (that's the $2B), which includes the slide to unlock feature.

As The Guardian reports:

Apple claims the following Samsung products now infringe on Apple patents: Admire, Galaxy Nexus, Galaxy Note, Galaxy Note II, Galaxy SII, Galaxy SII Epic 4G Touch, Galaxy SII Skyrocket, Galaxy SIII, Galaxy Tab II 10.1, and Stratosphere.

Samsung claims the following Apple products infringe on Samsung patents: iPhone 4, iPhone 4S, iPhone 5, iPad 2, iPad 3, iPad 4, iPad mini, iPod touch (5th generation), iPod touch (4th generation), and MacBook Pro.

More as the case goes on.
