SAN DIEGO, CAL, 2/23/12—Sequenom has filed a motion for a preliminary injunction against Aria Diagnostics trying to stop that company from making, using, and selling tests for trisomy 21. Sequenom says Aria's Harmony Prenatal Test infringes US PatentNo. 6,258,540 (Non-Invasive Prenatal Diagnosis), covering the MaterniT21 diagnostic test. An infringement suit was filed in January. Aria has eountersued, claiming that Sequenom is being overly aggressive in enforcing its patent on the harvest of fetalDNA from maternal blood. Such DNA is used in the aneuploidy tests. Sequenom also has sued Natera for infringing the patent, and Natera eountersued.
