Stryker Corporation v. Zimmer, Inc.
782 F.3d 649
Fed. Cir.2014Background
- Zimmer appeals district court ruling affirming jury verdicts that Stryker’s patents ’329, ’807, and ’383 are valid and infringed, and awarding damages; district court trebled damages for willful infringement and awarded attorneys’ fees; jury found infringement, validity, and willful infringement, and that Stryker’s products were properly marked; court remanded injunction and other relief.”
- “Pulsed lavage devices at issue are portable, battery-powered handpieces delivering irrigating fluid with suction; Stryker vs. Zimmer is a major market dispute in orthopedic pulsed lavage.”
- “’329 claim 2 covers a hand-held housing with a handle and a barrel, with motor located in the handle; ’807 claims require a front end for receiving discharge and suction tubes; ’383 concerns obviousness over Grulke, Drews II, and Bales.”
- “Zimmer argued non-infringement and invalidity defenses; Stryker's claim construction and infringement positions were contested but district court and jury accepted some arguments and rejected others.”
- “Court reverses willful infringement finding and vacates treble damages and attorneys’ fees; case remanded for further proceedings consistent with the opinion.”
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Is there substantial evidence of infringement and validity for the ’329 patent? | Stryker: construction of ‘handle’ covers device features; claimed motor location supports infringement. | Zimmer: motor not in handle; non-infringement under claim 2. | Affirmed infringement and validity findings; jury findings supported by record. |
| Does the ’807 patent infringement survive with the interface limitation requiring a front end to receive the tip? | Stryker: accused devices meet ‘receive’ in front-end interface. | Zimmer: ‘receive’ requires direct attachment; design uses opposite nozzle configuration. | Summary judgment of infringement affirmed; district court’s construction not clearly erroneous. |
| Was the ’383 patent obvious over Grulke, Drews II, and Bales? | Stryker: prior art would motivate combination; examiner’s related rejection supports validity. | Zimmer: skilled art would combine references; claims obvious. | Not obvious; reasonable jury could conclude no motivation to combine; affirm validity. |
| Was infringement willful and should trebled damages/attorneys’ fees be awarded? | Stryker: Zimmer acted with knowledge or reckless disregard of validity; willful infringement. | Zimmer: defenses were reasonable; objective reasonableness; prosecution history supports doubt. | Willful infringement reversed; trebled damages vacated; remand on exceptional-case/fees for district court. |
| Should marking findings support damages? | Not necessary to reach given other holdings; willful finding reversed. |
