CareDx first sued Natera in March 2019 for infringing two of its patents, then amended the suit a year later to add a third patent.

Natera claims that several Genosity products infringe its US Patent No. 10,732,220, titled "Methods for Simultaneous Amplification of Target Loci."

Last month, the court also ordered two separate patent lawsuits filed by Natera against ArcherDx this year to be consolidated into one.

Carlsbad, California-based BioSpyder said that HTG has repeatedly and baselessly accused it of infringing HTG's patent for quantitative nuclease protection assay and sequencing improvements.

Natera sued Progenity in June but the firm said its Innatal cell-free DNA noninvasive prenatal test does not infringe any of Natera's six patents.

The suit comes shortly after Progenity filed for an initial public offering in which it is seeking to raise up to $122.6 million.

In its complaint, the Maryland-based company claimed that Natera infringes two of its patents, both titled "Methods for detection of genetic disorders."
