“Bloomberg” (http://macte.ch/OM7WF) reports that an US trade judge has ruled that Samsung infringes four Apple patents, including one for the design of the iPhone and one for touch-screen technology.

Two other patents, including one for the exterior shape of the iPhone, weren’t infringed, U.S. International Trade Commission Judge Thomas Pender said in a notice on the agency’s website. The judge’s findings are subject to review by the full commission, which has the power to stop goods that infringe U.S. patents at the border.

This is all part of the ongoing, global legal battle. Apple and Samsung have filed more than 30 lawsuits against each other across four continents. For example, Apple alleges that Samsung copied the slide-to-unlock technology of its iPhone and iPad devices.
