Illumina has filed a new patent infringement based on Ariosa’s infringement of US patent number 7,955,794, entitled ‘Multiplex Nucleic Acid Reactions’ in the US District Court for the Northern District of California.
The suit targets Ariosa’s Harmony prenatal test, including its use of digital analysis of selected regions (DANSR) that, among other things, enables simultaneous quantification of hundreds of DNA loci.
The company previously sued Ariosa for infringement of U.S. Patent No. 8,296,076 and U.S. Patent No. 8,318,430 in the U.S. District Court for the Northern District of California.
The Court in that case issued a Claim Construction Order providing the Court’s interpretation of the disputed patent terms which supports the position that Ariosa infringes those patents.
Illumina offers the verifi non-invasive prenatal test in its CLIA-certified, CAP-accredited clinical services laboratory, to detect chromosome abnormalities and aberrations with improved resolution for consistent and dependable results.
