Boston Scientific Corp. v. Cook Medical LLC (claim construction & validity)

Defendant: Cook Medical LLC

Court: D. Del.

Date: Apr 14, 2017

Docket: 15-980-LPS-CJB

Judge: District Judge Leonard P. Stark

The court construed 2 claim terms in U.S. Patent No. 8,974,371 and 1 claim term in U.S. Patent No. 8,709,027.  In the ‘371 patent, the court construed the term “tension member” to mean “a member that fits inside the capsule, is positioned between the clip arms, and engages the clip arms to urge them radially outward.”  In the ‘371 patent, the court construed the term “opening element” to have its plain and ordinary meaning. In the ‘027 patent, the court construed “a linkage” to mean “a system of interconnected machine parts used to transmit power or motion.”

The court also determined that the term “linkage” was not indefinite and therefore the ‘027 patent was not invalid.
