Opinion

MEMORANDUM AND ORDER

KEETON, District Judge.

Now before the court are Defendant’s Motions for Summary Judgment in the consolidated cases brought by Flowoptic Sensors and David Hoppe. Because the cases were consolidated (Docket No. 21, July 7, 1994) after some of the papers pertinent to these motions were filed, there is occasional coincidental overlap in docket numbers.

The following documents relating to defendant’s summary judgment motion against Flowoptic Sensors, Inc., are before the court:

Defendant’s Motion for Summary Judgment (Docket No. 8, filed July 7,1994) and Memorandum in Support, with affidavits attached as exhibits (Docket No. 9);
Plaintiffs Memorandum in Opposition (Docket No. 25, filed August 30, 1994) and the Affidavits of David E. Hoppe (Docket No. 26) and Walter D. Wekstein (Docket No. 27);
Defendant’s Reply Memorandum (Docket No. 34, filed September 15, 1994);
*306 Plaintiffs Statement of Contested Facts (Docket No. 37, filed September 22, 1994), with a Supplemental Declaration of David E. Hoppe attached as Exhibit D;
Defendant’s Motion to Strike Plaintiffs Supplemental Declaration of David Hoppe (Docket No. 42, filed September 28, 1994); Plaintiffs Memorandum in Opposition to Defendant’s Motion to Strike Plaintiffs Supplemental Declaration of David Hoppe (Docket No. 43, filed October 3, 1994). Plaintiffs [Supplemental] Memorandum in Opposition to Defendant Baxter’s Motion for Summary Judgment (Docket No. 48, filed January 26, 1995), with supporting materials (Docket No. 49), and Defendant’s Reply (Docket No. 54, filed February 2, 1995).

The following documents relating to defendant’s summary judgment motion against David Hoppe are before the court:

Defendant’s Motion for Summary Judgment (Docket No. 8, filed May 24, 1994) and Memorandum in Support, with an affidavit and other exhibits (Docket No. 9), and Defendant’s Statement of Uncontested Facts (Docket No. 7);
Plaintiffs Memorandum in Opposition (Docket No. 13, filed June 7,1994), accompanied by Declaration of David Hoppe in Opposition (Docket No. 12);

Letter from Defendant Baxter (Docket No. 35, filed September 15, 1994).
Letter from Defendant Baxter (Docket No. 50, filed February 1, 1994).

I

The two consolidated actions present different claims by different, but related plaintiffs. David E. Hoppe (“Hoppe”) has sued Baxter Healthcare, Inc. (“Baxter”) for patent infringement. A counterclaim by Baxter against Hoppe seeks a declaratory judgment of non-infringement. Flowoptic Sensors, Inc. (“Flowoptic”) has sued Baxter for breach of contract. A counterclaim by Baxter against Flowoptic seeks the balance due for a shipment of goods.

Baxter seeks summary judgment against both plaintiffs, but not for all claims. Baxter seeks summary judgment against Flowoptic on Flowoptic’s breach of contract claim, but not on Baxter’s counterclaim for balance due. Baxter seeks summary judgment against Hoppe on the claim of infringement and Baxter’s necessarily related counterclaim of non-infringement.

A. The Infringement Action (Hoppe v. Baxter)

Both the infringement and contract causes of action concern a device called a bearing-less flowmeter that is used to measure the low rates of fluid flow. A typical flowmeter has an inlet for receiving fluid; a jet ring with passages that convey the fluid to a rotor, which spins within a vortex chamber; and an outlet that allows the fluid to escape. The incoming fluid, once it passes through the holes in the jet ring, reaches the rotor and causes it to spin. The number of revolutions of the rotor is measured by an optical sensor to determine the amount of fluid that passes through the flowmeter.

The bearingless flowmeter was patented in 1969 by an inventor named McNabb. The device, however, did not provide a perfect measure of fluid flow because the rotor brushed against the walls of the vortex cham *307 ber rather than spinning perfectly freely within the chamber.

A key challenge to developers of the flow-meter was, and apparently remains, to stabilize the rotor so that it does not brush against the walls of the vortex chamber as it spins. Plaintiff Hoppe experimented in the early 1970s with variations in the number of jet passages, believing that it was the number of passages that determined the stability of the rotor. He concluded that the flow-meter would not work satisfactorily unless there were more than eight jets.

Hoppe applied for a patent for this discovery. Initially, he was turned down; ultimately, he received U.S. Patent No. 4,015, 474 (“the Hoppe Patent”, or “the ’474 patent”).

The ’474 patent contains only one claim. That claim, in relevant part, is for “[a]n improved rotor-stabilized bearingless flow-meter comprising ... at least nine circumferentially spaced jet passages.” The particular components of the bearingless flowmeter— notably, the jet ring and the rotor — are not separately patented.

Hoppe developed a plastic version of the flowmeter. His company, Bearingless Flow-meters, manufactured the flowmeter for the Renal Care Division of Johnson & Johnson in 1981-82, which used it in dialysis machines. After the Renal Care Division was sold to what is now Baxter Healthcare Corporation, Jack Goss, a former research and development manager with that division, formed a venture with Hoppe in 1985, Digital Precision, that continued to manufacture the flow-meters for Baxter’s Renal Care Division. Mr. Goss had access to all the dimensions and materials compositions of the flowmeter as it had been developed by Hoppe.

From 1985 until its demise in 1990, Digital Precision sold only completly assembled dialysis flowmeters to Baxter, a maker of dialysis and other machines. But Digital Precision was not a completely rehable supplier, so Baxter preferred to purchase key components, such as jet rings and rotors, from Bearingless (also a Hoppe corporation) in Massachusetts. Baxter would sell these components back to Digital Precision, which would, in turn, incorporate them into its assembly of complete flowmeters.
