In response to a lawsuit filed by Myriad Geneics against rival Ambry Genetics accusing Ambry of patent infringement, Ambry has filed its own countersuit against its competitor for alleged antitrust violations. Reports say Ambry filed its own lawsuit in California on Tuesday, alleging Myriad’s initial claim violated antitrust law and “are invalid under two Supreme Court decisions and Federal Circuit authority.” The Supreme Court ruled last month that Myriad cannot hold patents on certain gene sequences. Myriad soon after filed a lawsuit claiming a testing process used by Ambry for detecting mutations in such gene sequences violated Myriad’s patent; Myriad claims that despite the Supreme Court ruling, it still holds valid claims in 24 patents.
