Ruling Issued in Rudolph's Patent Infringement Case against Camtek

On Monday, August 22, 2011, the U.S. Federal Circuit Court of Appeals issued a ruling in Rudolph Technologies' long-running patent infringement case against Camtek, Ltd. in the Federal District Court for the District of Minnesota. In its opinion, the Appellate Court affirmed multiple rulings from trial at the District Court level including finding Rudolph's U.S. Patent No. 6,826,298 valid, the part of the infringement ruling based on the finding that Camtek's Falcon product strobes "based on velocity," and the dismissal of Camtek's claim against Rudolph for inequitable conduct against the U.S. Patent and Trademark Office. The court did, however, revise one claim construction ruling made by the District Court in the original case and remanded it back to the trial court. Robert Koch, Rudolph's vice president and general counsel, stated "While we are disappointed that the court did not affirm all aspects of our verdict against Camtek, we are very pleased to note that the court determined that our patent is valid and that the remaining issue before the District Court is one about which we feel very confident."

As part of its ruling, the Appellate Court sent a single issue back to the District Court for resolution in a "limited" proceeding that relates to whether Camtek's Falcon product creates a model using multiple, discrete afers. "As Rudolph presented solid evidence that Camtek uses multiple whole wafers with the Falcon to train the system, we look forward to a prompt and favorable resolution to this matter with the reinstatement of the judgment of infringement, damages and the permanent injunction," said Mr. Koch.
