Illumina Sues Ariosa Diagnostics, Roche Molecular Systems Over Patent

San Diego-based lifesciences equipment maker Illumina said Monday that it has filed a new patent infringement suit, against Ariosa Diagnostics and parent company Roche Molecular Systems. The new lawsuit alleges infringement of U.S. Patent 7,955,794, which Illumina says Ariosa is infringing upon in one of its products. The new lawsuit was filed in the U.S. District Court for the Northern District of California. Illumina said the lawsuits are on top of an existing lawsuit that had been filed by its subsidiary, Verinata Health, against Ariosa. Illumina acquired Verinata in 2013.
