Maquet Cardiovascular LLC v. Abiomed Inc. et al. (D. Mass 17-cv-12311).
A jury found that Abiomed's Impella intravascular pumps did not infringe Maquet's patent under the reverse doctrine of equivalents, despite meeting literal claim limitations, and determined the asserted patent claim was invalid for failing written description and enablement requirements. The case now awaits a judicial determination on whether assignor estoppel should preclude Abiomed from challenging the patent's validity.
