Illumina Comments On A Ruling In Its Patent Litigation Against Complete Genomics, Inc.

Illumina, Inc. (NASDAQ: ILMN) announced today that Magistrate Judge Elizabeth D. LaPorte of the U.S. District Court for the Northern District of California granted a motion for summary judgment of invalidity filed by Complete Genomics, Inc. against certain claims of Illumina’s U.S. Patent No. 6,306,597. Over Illumina’s objections, the Court found that these claims were not novel over the prior art. The summary judgment ruling did not address a number of additional patent claims being asserted by Illumina against Complete Genomics that were not the subject of the validity motion.

Jay Flatley, Illumina’s President and Chief Executive Officer, stated, “We strongly disagree that any of the claims of our patent are invalid, and we intend to appeal the Court’s ruling. We believe that this patent covers important and novel inventions that Complete Genomics has misappropriated.” Illumina also continues to vigorously protect its rights under a second patent that Illumina more recently asserted against Complete Genomics in the U.S. District Court for the Southern District of California.
