Stryker v. Zimmer Surgical

On May 18, 2015, the district court for the Western District of Michigan issued a joint proposed amended final judgment and permanent injunction in favor of Stryker Corporation, et al. (“Plaintiffs”).  In the decision, the court held that Zimmer, Inc. and Zimmer Surgical, Inc. (“Defendants”) infringed, literally and under the doctrine of equivalents, certain claims of U.S. Patent Nos. 6,022,329 (“the ‘329 Patent”), 6,179,807 (“the ‘807 Patent”), and 7,144,383 (“the ‘383 Patent”) through the Defendants’ manufacture, use, sale, offer for sale, and/or importation of its pulsed lavage products.  The ‘329 Patent, the ‘807 Patent, and the ‘383 Patent, which are owned by the Plaintiffs, are drawn to surgical/medical irrigators and/or irrigating handpieces. The court further award various damages to the Plaintiffs and issued a permanent injunction prohibiting Defendants from manufacturing, using, importing, selling, or offering for sale the pulsed lavage products found to infringe the ‘807 Patent. The case remains pending and is captioned 1:10-cv-01223.
