Maquet Cardiovascular LLC v. Abiomed Inc. Et Al. (D. Mass 17-cv-12311).
Maquet accused Abiomed of patent infringement involving intravascular blood pumps with steerable cannulas. The case centers on whether a patent claiming a blood pump genus is invalid for failing to describe internal motor species when only external motors were disclosed in the specification. Judge Saylor's ruling on summary judgment motions reveals critical questions about written description requirements and what constitutes claimed versus unclaimed elements in patent disputes.
