Opinion

ORDER

WARREN, District Judge.

Before the Court is the defendant’s Motion for Summary Judgment pursuant to Federal Rule of Civil Procedure 56 (“Rule 56”) in the above-captioned matter. For the following reasons, this motion is denied, and the parties shall appear at a pretrial conference before this Court on Tuesday, July 19, 1994 at 9:00 o’clock a.m. in Room 364 of the United States Courthouse, 517 E. Wisconsin Avenue, Milwaukee, Wisconsin, 53202.

I. BACKGROUND FACTS

A. Factual Background:

Plaintiff Criticare Systems, Inc. (“Criticare”) is a Delaware Corporation with its principal place of business in Waukesha, Wisconsin. (Def. Proposed Findings of Fact, PL Resp. to Def. Proposed Findings of Fact at ¶ 1.) Defendant Nellcor Inc. (“Nellcor”) is a Delaware Corporation with its principal place of business in Hayward, California. (Id. at ¶ 2.) The Court has subject matter jurisdiction over this action pursuant to 15 U.S.C. § 1121(a) and pendent jurisdiction over state claims. (Id. at ¶ 3.) We have personal jurisdiction over Nellcor because it transacts business in Wisconsin, and proper venue pursuant to 28 U.S.C. § 1391. (Id. at ¶¶ 4, 5.)

Criticare and Nellcor are competing sellers in the market for pulse oximeters; Nellcor has a market share of approximately 50%, while Criticare’s market share approaches 15%. (Id. at ¶ 6; Pl. Proposed Finding of Fact, Def. Resp. to PL Proposed Findings of Fact at ¶¶ 1, 2.) Pulse oximeters are used by anesthesiologists and other medical professionals to nonintrusively measure a patient’s arterial blood oxygen saturation by shining light through the skin to detect the amount and quality of light emitted as the patient’s pulse beats. (Def. Proposed Findings of Fact, Pl. Resp. to Def. Proposed Findings of Fact at ¶¶ 7, 11.) In order to ensure that there is enough blood at the receptor sight to obtain an accurate reading, a pulse oximeter measures oxygen saturation only on the pulse. (Id. at ¶ 12.)

Depending on the mode selected, Criticare’s pulse oximeter presents either a pulse waveform, EKG waveform, or “trend data;” the pulse waveform demonstrates the existence and strength of the pulse that the sensor is detecting, while the EKG waveform apparently demonstrates the existence of a pulse only. (PL Proposed Findings of Fact, Def. Resp. to PL Proposed Findings of Fact at ¶ 11.) When used on pulse waveform, a bar graph on the monitor shows the existence and quality of the pulse, and the machine emits a pulse tone corresponding to the pace of the pulse and the level of blood *498 oxygen saturation; when on EKG waveform, the blip bar beats with the EKG. (Id.) As a patient’s blood oxygen saturation falls, the pulse tone becomes lower and the pulse wave flattens. (Id. at ¶ 12.)

When a patient’s pulse stops or becomes erratic, no pulse oximeter can detect his or her blood oxygen saturation level. (Id. at ¶ 9; Def. Proposed Findings of Fact, PI. Resp. to Def. Proposed Findings of Fact at ¶ 13.) In such circumstances, the Criticare pulse oximeter displays the last recorded saturation level for forty (40) seconds while it continues to search for a pulse; when on pulse waveform mode, it also displays a flat pulse wave, the bar graph disappears from the monitor, and the pulse tone ceases. (Id. at ¶ 12; PI. Proposed Findings of Fact, Def. Resp. to PI. Proposed Findings of Fact at ¶¶ 10, 14.) According to the defendant, if used on EKG waveform mode when the pulse is lost, the Criticare pulse oximeter will emit a pulse tone at the rate of the heart beat and at a level matching the last recorded saturation level. (Id. at ¶ 12.) If it fails to detect a pulse within forty (40) seconds, the Criticare pulse oximeter sounds an alarm. (Def. Proposed Findings of Fact, PL Resp. to Def. Proposed Findings of Fact at ¶ 10.)

Criticare markets its pulse oximeters at a price lower than that charged by Nellcor, due (at least in part) to the fact that Criticare heavily markets its reusable sensors, while Nellcor sells a higher proportion of disposable sensors. (Id. at ¶¶ 4, 5.) From 1990 to 1991, several major hospitals switched from Nellcor’s product to Criticare’s pulse oximeters and reusable sensors, including Long Beach Memorial Hospital in Long Beach, California, California Desert Samaritan Hospital in Phoenix, Arizona and the Medical College of Virginia Hospitals (“MCVH”) in Richmond, Virginia; Criticare also entered into a preferred-vendor agreement with a group purchasing agent called American Health Care Systems. (Id. at ¶ 7.) Over that same period, Nellcor sold approximately $2,225,000 worth of disposable sensors to nearly one hundred (100) hospitals affiliated with Premier Hospitals Alliance, Inc. (“Premier”), a large group purchasing organization. (Id. at ¶ 6.)

The Child Health Corporation of America (“CHCA”) is a not-for-profit corporation whose membership includes twenty-five (25) children’s hospitals; it acts as a group purchasing organization in order to obtain better pricing for its members. (Def. Proposed Findings of Fact, PL Resp. to Def. Proposed Findings of Fact at ¶¶ 28, 29.) A separate corporate division of the CHCA is the Alliance of Children’s Hospitals (“the Alliance”), which, inter alia, awards seals of approval to certain medical devices. (Id. at ¶¶30, 32.) It was for this purpose that the Alliance's pulse oximetry task force met in Kansas City, Missouri on August 28, 1991 to hear presentations from both Criticare and Nell-cor regarding their respective products. (Id. at ¶ 34.)

At that meeting, Nellcor representatives displayed on an overhead projector a July 22, 1991 letter written to Curtiss G. Plaskon, the Director of Respiratory Care Services at MCVH, by Dr. Gary Lofland, the Director of Pediatric Cardiac Surgery and Medical Director of Cardiac Surgery, Intensive Care Unit, at MCVH, and an associate professor of both pediatrics and surgery at the Medical College of Virginia. (Id. at ¶¶ 8-10.) That letter read as follows:

“Dear Mr. Plaskon:
On the evening of July 16, 1991, we experienced another unfortunate episode involving the Criticare pulse oximeters. At that time, a 2 kg neonate who had successfully undergone an arterial switch procedure, closure of ventricular septal defect, closure of atrial septal defect, and ligation, division of patent ductus arteriosus experienced what can only be described as a pulmonary hypertensive crisis 1 which was not detected by the Criticare pulse oximetry system.

*499 The child in question was doing extremely well, and experienced a very sudden demise, with a 98% saturation frozen on the pulse oximeter screen.
