Case: Patents/Summary Judgment (D. Mass.)

A federal district court in Massachusetts denied Abiomed Inc., Abiomed R&D Inc., and Abiomed Europe GmbH’s motion for partial summary judgment of no infringement under the doctrine of equivalents in Maquet Cardiovascular LLC’s patent infringement action relating to a patent for intravascular blood pumps. The court found that Maquet raised genuine disputes about whether the differential and optical pressure sensors in Abiomed’s products were equivalent to the fluid-column pressure sensor claimed in the patent, based on expert testimony that must be evaluated at trial.
