AmniSure International LLC declared victory in its seven-year patent fight with a Finnish company.
The High Court of Germany voided the Medix Biochemica patent associated with that firm’s Actim PROM test for detection of premature rupture of fetal membranes, according to AmniSure. The court ruled that Medix’s patent lacked a so-called "inventive step," meaning it is too closely related to previously patented technology.
