Feb 26 A U.S. appeals court on Friday overturned a $120 million jury verdict against Samsung, finally handing the South Korean smartphone maker a significant win in its longstanding patent feud with top rival Apple. The U.S. Court of Appeals for the Federal Circuit in Washington, D.C., said Samsung Electronics Co Ltd did not infringe Apple's "quick links" patent, and that two other patents covering the iPhone's slide-to-unlock and auto-correct features were invalid.
