Before NEWMAN, LOURIE, and BRYSON, Circuit Judges.

LOURIE, Circuit Judge.

Molten Metal Equipment Innovations, Inc. and Paul V. Cooper (collectively "MMEI") appeal from the decisions and orders of the United States District Court for the Northern District of Ohio in which the court entered a permanent injunction against MMEI based on a jury verdict of infringement of U.S. Patent 4,169,584 (the '584 patent), which is owned by the Carborundum Company d/b/a Metaullics Systems Division and Metaullics Systems Co. L.P. (collectively "Metaullics"); granted Metaullics' motion for judgment as a matter of law on MMEI's implied license defense; denied MMEI's motion to modify the permanent injunction; and held MMEI in civil contempt for violation of the court's injunction. Carborundum Co. v. Molten Metal Equip. Innovations, Inc., No. 1:92 CV 2106 (N.D.Ohio April 21, 1994) (issuing permanent injunction against MMEI); Carborundum Co. v. Molten Metal Equip. Innovations, Inc., No. 1:92 CV 2106 (N.D.Ohio April 22, 1994) (granting judgment as a matter of law for Metaullics on MMEI's implied license defense); Carborundum Co. v. Molten Metal Equip. Innovations, Inc., No. 1:92 CV 2106 (N.D.Ohio May 4, 1994) (denying MMEI's motion to modify the permanent injunction); Carborundum Co. v. Molten Metal Equip. Innovations, Inc., No. 1:92 CV 2106 (N.D.Ohio September 6, 1994) (holding MMEI in civil contempt). Metaullics cross-appeals, challenging the amount of damages awarded based on the court's contempt finding. We affirm.

BACKGROUND

Metaullics manufactures and sells equipment used in various systems in the aluminum industry, including molten metal purification systems. These purification systems introduce gases into molten metal in order to remove dissolved gases, such as hydrogen, or dissolved metals, such as magnesium, from the molten metal. These gases chemically react with the impurities to form a compound that either floats to the surface of the molten metal and is skimmed off or is released from the molten metal into the atmosphere.

Metaullics owns the '584 patent for a "Gas Injection Apparatus," which issued on October 2, 1979.1 The invention is directed to a complete system for melting scrap metal and removing impurities from the metal. Metaullics does not have a patent on any of the individual elements of the claimed system. Claim 1, the only independent claim at issue, defines the invention as follows:

1. A gas injection apparatus for introducing gas into molten metal, comprising:

(1) a reverberatory furnace;

(2) means within said reverberatory furnace for pumping metal through a metal transfer conduit, said pumping means having a pumping capacity of at least 4000 lbs/min, said metal transfer conduit being at least partially submerged in a metallic bath;

(3) a two-ended gas injection conduit having one end submerged within the metallic bath and connected to the metal transfer conduit, the gas injection conduit being so constructed and arranged that the metal is pumped past the submerged end of the gas injection conduit so as to contact the gas within the gas injection conduit connected to the metal transfer conduit, the gas injection conduit having an unsubmerged end opposite the submerged end of the gas injection conduit; and

(4) means for providing gas to be introduced into the molten metal into the unsubmerged end of the gas injection conduit.

Instead of selling the entire apparatus as claimed in the '584 patent, Metaullics sells a pump with a metal transfer conduit and a gas injection conduit. The pump is designed specifically for use in the system described in the '584 patent. Metaullics does not sell a reverberatory furnace or a gas supply. When it sells its pump, Metaullics does not provide any notice of the '584 patent or place any restrictions on its customers' use of the pump.

In addition to selling pumps, Metaullics sells replacement parts for its pumps. Because a portion of the pump is submerged in molten metal, certain parts of the pump must be made of a nonmetallic material, such as graphite or ceramic. Although these parts are more durable in molten metal than metal parts, they still require frequent replacement. In fact, Metaullics estimates that it costs about $35,000.00 a year in replacement parts for a pump that initially cost between $8,000.00 and $20,000.00.

MMEI also sells molten metal pumps, the "WORKHORSE" and "MONSTER" pumps, and replacement parts for those pumps.2 Most of MMEI's pump sales in this case were to customers who previously purchased a Metaullics pump and then replaced it with an MMEI pump.3 MMEI does not dispute that Metaullics' customers substituted the MMEI pump for the Metaullics pump and continued to use the apparatus of the '584 patent.

On October 7, 1992, Metaullics sued MMEI, alleging that the sale of MMEI's pumps constituted contributory infringement and inducement of infringement under 35 U.S.C. Secs. 271(b) and (c) (1988). Beginning on April 5, 1994, the court held a bifurcated trial in which the issues of infringement and damages were tried separately to the same jury. At the close of the evidence in the liability phase of the trial, Metaullics moved for judgment as a matter of law on MMEI's defense that its customers did not directly infringe the '584 patent.4 See Fed.R.Civ.P. 50. The court granted Metaullics' motion and directed a verdict in favor of Metaullics on MMEI's implied license defense. Carborundum Co. v. Molten Metal Equip. Innovations, Inc., No. 1:92 CV 2106 (N.D.Ohio April 22, 1994). In particular, the court held that Metaullics' initial sale of a pump did not grant its customers an implied license to use the apparatus of the '584 patent for the life of the patent. Id., slip op. at 3. The court determined that when Metaullics sold a pump, the customer received an implied license under the '584 patent for the life of the purchased pump. Id., slip op. at 5. Therefore, the court held that Metaullics' customers would infringe the '584 patent when they placed MMEI's pump into their metal purification systems.
