Rambus (RMBS) - Get Report was up 1.5% in preopen Island trading despite a jury ruling Wednesday that said the chip designer and manufacturer was liable for fraud. The jury ordered it to pay punitive damages of $3.5 million in its battle with the German chipmaker Infineon (IFX) .

The decision is the second court loss, as a judge last week threw out the company's three remaining patent infringement claims against Infineon. Rambus said it plans to appeal both decisions.
