The jury found that both Ariosa's previous and current version of the Harmony non-invasive prenatal test (NIPT) infringe US Patent 8,318,430 and US Patent 7,955,794. The jury awarded Illumina approximately $26.7 million for past damages.
The jury rejected counterclaims by Ariosa that Illumina had breached a supply agreement between the companies by bringing the lawsuit.
The US Patent and Trademark Office previously upheld the validity of the patents rejecting multiple challenges filed by Ariosa.
"We are pleased with the outcome reached by the jury," said Charles Dadswell, senior vice president and general counsel for Illumina. "This verdict again validates these patents, the hard work and ingenuity of the inventors, and their significant contribution to the field of NIPT."
Illumina intends to seek injunctive relief for ongoing infringement by Ariosa's continuing sale of its Harmony test.
