Illumina Files Patent Infringement Suit Against Ariosa Diagnostics

San Diego-based lifesciences equipment maker Illumina announced late Friday that it has filed a new, patent infringement lawsuit, against Ariosa Diagnostics. Illumina claims that Ariosa's products are an infringement of its U.S. Patent, No. 7,955,794, entitled "Multiplex Nucleic Acid Reactions." Ariosa is a maker of a prenatal diagnosis and screening test. Illumina said the new lawsuit follows an earlier, patent infringement suit filed by Verinata Health--which is now part of Illumina.
