Mallinckrodt, Inc. v. Medipart, Inc., 976 F.2d 700, 61 USLW 2204, 24 U.S.P.Q.2d 1173

Facts

Mallinckrodt, the manufacturer of a patented medical device, sold the device to hospitals with a 'single use only' restriction. After initial use, hospitals sent the devices to Medipart for servicing, allowing them to be reused. Mallinckrodt claimed that this practice induced infringement of its patent rights. The district court granted summary judgment of noninfringement, stating that the restriction could not be enforced under patent law. Mallinckrodt appealed the decision.

Issue

Is the restriction prohibiting the reuse of a patented medical device enforceable under patent law?

Is the restriction prohibiting the reuse of a patented medical device enforceable under patent law?

Rule

A restriction on the use of a patented device is enforceable under patent law if it is reasonably within the scope of the patent grant. Such restrictions may be deemed unenforceable if they extend beyond the patent grant and have anticompetitive effects not justifiable under the rule of reason. The right to exclude may be waived in whole or in part, and conditions of such waiver are subject to patent, contract, antitrust, and equitable considerations.

Analysis

The court analyzed whether Mallinckrodt's restriction on reuse was valid under patent law. It determined that the restriction was related to the subject matter within the scope of the patent claims and did not violate antitrust laws or patent misuse. The court noted that the enforceability of the restriction does not depend on whether the purchaser acquired the device from the patentee or a licensee. The district court's ruling that no restrictions could be imposed was found to be incorrect.

Conclusion

The court reversed the district court's summary judgment of noninfringement, holding that the restriction on reuse was enforceable under patent law.

Reversed and remanded.

Who won?

Mallinckrodt prevailed in the appeal, as the court found that the restriction on reuse of its patented medical device was enforceable under patent law. The court emphasized that the restriction was within the scope of the patent grant and did not violate antitrust laws. The ruling clarified that the enforceability of such restrictions is valid as long as they do not extend beyond the patent grant and are not deemed anticompetitive.
