The Federal Circuit has resurrected two semiconductor suits brought by Lone Star Silicon Innovations LLC (Lone Star) against Nanya Technology and UMC but dismissed for lack of standing last January. While the Federal Circuit agreed with District Judge William Alsup that Lone Star could not file suit on its own—based on the fact that when it acquired the patents from AMD, that company had retained significant rights—the appeals court held that Judge Alsup erred by declining to consider the NPE’s request to join AMD as a necessary party. The Federal Circuit has remanded the cases for consideration of that issue.
