Mid-State Stainless, Inc. (Mid-State), appeals from the rejection of its patent invalidity counterclaim and from the denial of its motion to amend the judgment to include a declaratory judgment of non-infringement and a judgment that it had not breached a patent license agreement. We affirm in part, reverse in part, vacate in part, and remand.
I.
This is a patent case involving a machine designed to wash wheelchairs, the idea for which was originally conceived by Walter
Contemporaneous with the filing of the ’091 application, Schinzing made arrangements with Elm Springs Enterprises to manufacture his washer. Shortly thereafter, he permitted four students from Dr. Lou Honary’s Methodology and Conceptualization class at the University of Northern Iowa to analyze the washer design over the course of a two-semester class project. 1 The students recommended improvements to the washer in a written report entitled “Wheel-Chair Modifications Proposal” (the student report). The students also demonstrated a version of the washer that incorporated their recommended improvements to an audience that included Schinzing, Dr. Honary, other students and professors, partners of Elm Springs, and a member of Congress (the student demonstration).
In October 1989, Schinzing filed a second patent application (the ’119 application), which was a continuation-in-part of the ’091 application. The ’119 application incorporated the improvements recommended by the students and included several of the students’ drawings. Schinzing maintained that he was the sole inventor of the modified washer. After the PTO rejected the ’119 application, 2 Schinzing continued to work on further modifications to the washer. He and several other members of Elm Springs filed a third patent application in November 1990 (the ’757 application). The subsequently amended ’757 application presented an independent claim consisting of seven elements and a second claim dependent on the first. The PTO issued patent number 5,133,375 (the ’375 patent) for the amended ’757 application in July 1992.
In April 1993, Schinzing, in partnership with a woman named Sue Spaulding (collectively, S/S Products), entered into a license agreement with Mid-State under which Mid-State would develop, manufacture, use, and market the washer. Mid-State agreed to pay S/S Products a royalty of $400 for each washer that it installed. Mid-State manufactured and sold 99 washers under the agreement and paid royalties on those washers. After S/S Products terminated the agreement in February 1998, Mid-State sold an additional 232 washers but did not pay royalties on them.
Schinzing sued Mid-State in Minnesota state court, alleging that Mid-State had breached the license agreement by failing to pay royalties on the washers that it sold after the termination of the agreement. Mid-State removed the case to federal court, raised ten affirmative defenses, and counterclaimed for a declaratory judgment of patent invalidity and non-infringement. The parties consented to a trial before a magistrate judge. After a two-day bench trial, the district court concluded that Mid-State had breached the license agreement and that the ’375 patent was not invalid. Mid-State filed a motion to amend the judgment to include a declara
II.
We briefly address the question of jurisdiction. This case involves substantive issues of patent law that are usually adjudicated in the Court of Appeals for the Federal Circuit. We are required to exercise jurisdiction, however, under the holding of
Holmes Group v. Vornado Air Circulation,
In examining this case, we adopt the Federal Circuit’s precedent on substantive issues of patent law.
III.
We turn first to Mid-State’s counterclaims of patent invalidity, because if we conclude that the patent is invalid then we need not consider whether Mid-State was guilty of infringement.
See Lough v. Brunswick Corp.,
A.
The first step in any invalidity analysis is claim construction.
Akamai Techs., Inc. v. Cable & Wireless Internet Servs., Inc.,
The district court failed to construe the claims of the ’375 patent. It is true that a trial court need not parse claims when there is no “issue in material dispute as to the meaning or scope of the claims.”
U.S. Surgical Corp. v. Ethicon, Inc.,
We note that on remand the district court’s comparison of the ’375 patent to the device described in the student report and the device shown in the student demonstration should reflect the Federal Circuit’s observation that 35 U.S.C. § 102(b) may bar patentability by anticipation if the earlier device includes every limitation of the later claimed invention, or by obviousness if the differences between the claimed invention and the earlier device would have been obvious to one of ordinary skill in the art.
Netscape Communications Corp. v. Konrad,
B.
Mid-State contends that the patent is invalid because Schinzing engaged in inequitable conduct before the PTO. 3 Specifically, Mid-State asserts inequitable conduct based on Schinzing’s failure to identify in the ’757 application: (1) Schinzing’s previously rejected patent applications (the ’091 application and the ’119 application); (2) a prior patent (the Haverberg patent); (3) the student co-inventors; (4) the student report; and (5) the student demonstration.
A district court’s determination regarding inequitable conduct before the PTO is reviewed for abuse of discretion.
PerSeptive Biosystems v. Pharmacia Biotech, Inc.,
The district court’s findings on materiality and intent are reviewed for clear error, and thus will not be overturned in the absence of a definite and firm conviction on the part of the reviewing court that a mistake has been made.
Hoffmann-La Roche, Inc. v. Promega Coup.,
The district court found that “there was no evidence at trial that Mr. Schinzing intentionally withheld anything from the Patent and Trademark Office” and that “Mr. Schinzing consistently testified that the student proposal was an educational opportunity provided to the students as part of their undergraduate course requirements and that the students’ proposal was not a significant part of the invention as finally patented.” D. Ct. Order of May 18, 2004, at 23. Although the district court did not specifically address Mid-State’s allegations of inequitable conduct based on Sehinzing’s failure to disclose the prior patent applications, the Haverberg patent, and the student report, the factual findings that these nondisclosures were not intentional is implicit in the district court’s finding that Schinzing did not intentionally withhold “anything” from the PTO. We conclude that the district court’s factual findings as to intentionality are not clearly erroneous. Because none of Schinzing’s nondisclosures was intentional, the district court did not err in finding that Schinzing did not engage in inequitable conduct before the PTO.
IY.
Although we are unable to determine whether the ’375 patent is invalid, we address Mid-State’s other issues on appeal in the interest of judicial economy. We review the denial of a Rule 59(e) motion to amend the judgment for abuse of discretion.
Mathenia v. Delo,
A.
A claim for a declaration of non-infringement makes a counterclaim for patent infringement compulsory.
Polymer Indus. Prods. Co. v. Bridgestone/Firestone, Inc.,
B.
Schinzing’s allegation that Mid-State breached the license agreement is premised on article VI(D) of the agreement, which provides, in relevant part, that:
Upon termination of this Agreement for any reason, [Mid-State] may after the effective date of such termination sell all Licensed Products in stock and complete construction of all Licensed Products in the process of manufacture at any time of termination and sell the same, provided that [Mid-State] shall pay to [S/S Products] royalties on such Licensed Products as specified in this Agreement.
License Agreement at 5. 4 The district court concluded that “[t]o the extent that Mid-State breached [the] agreement after the date of termination, the appropriate measure of damages is the calculation of a reasonable royalty on all machines sold which embodied the licensed patent and/or technology.” D. Ct. Order of May 18, 2004, at 25.
The district court’s conclusion fails to distinguish between breach and infringement. The license agreement obligated Mid-State to pay Schinzing royalties on any washers that were either in stock or in the process of manufacture when the agreement was terminated. Schinzing may assert a claim for breach of contract against Mid-State for its failure to pay post-termination royalties on those washers. In contrast, any washers that Mid-State manufactured completely post-termination fell outside the scope of the license agreement, and Schinzing has no contractual remedy against Mid-State for its manufacture and sale of those washers. To conclude otherwise would mean that the agreement was irrevocable, an interpretation precluded both by Article VI of the agreement (“[u]nless terminated earlier, the term of this Agreement shall be
When Schinzing terminated the agreement, Mid-State “no longer [had] any right to the use of the licensed patent or technology.” License Agreement at 5. Accordingly, the appropriate recourse for Schinzing would have been an infringement action. That possibility, however, is now barred by our holding in part IV(A), supra.
We are left, then, to consider Schinzing’s breach of contract claim with respect to those washers sold by Mid-State that were either in stock or in the process of manufacture when the agreement was terminated. Although we have held that Mid-State did not infringe the ’375 patent in its manufacture and sale of the washers, it may still have breached the license agreement by failing to pay royalties in accordance with that agreement. On the other hand, if the district court concludes on remand that the ’375 patent is invalid, then it will have to address Mid-State’s affirmative defense that the license agreement is invalid for lack of consideration. 5 Accordingly, we remand the breach issue. We also note that the record does not reflect how many of the 232 washers that Mid-State sold after the agreement had been terminated were either in stock or in the process of manufacture at the time of termination. If the district court concludes that Mid-State breached the license agreement by selling, after the agreement had been terminated, washers that were either in stock or in the process of manufacture at the time of termination, the district court will have to make a factual finding regarding the number of washers sold post-termination that fell within that category.
V.
We affirm the district court’s ruling that the ’375 patent is not unenforceable due to inequitable conduct. We vacate the district court’s ruling that the patent was not invalid with respect to inventorship, prior publication, and public use. We reverse the district court’s denial of Mid-State’s motion to amend the judgment to reflect a declaratory judgment of noninfringement and remand with direction to grant the motion. We vacate the district court’s ruling that Mid-State breached the license agreement, we vacate the damage award, and we remand for further proceedings consistent with this opinion.
Notes
. The undergraduate course was part of an engineering technology program. Honary Dep. at 5. Dr. Honary indicated that the students in the program were trained to be “somewhere between a technician and an engineer with a management component to learn to manage projects.” Id. at 6.
. Schinzing later abandoned the T19 application when he failed to respond to an August 1, 1990, letter from the PTO.
. Although the practical effect is generally the same, inequitable conduct renders a patent unenforceable rather than invalid.
Ulead Systems, Inc. v. Lex Computer & Mgmt. Corp.,

The license agreement defines "licensed products” as "any wheel chair cleaning assembly, subassemblies, components, replacement parts [or] other products which embody the Licensed Patent and Technology.” License Agreement at 1. The "licensed patent” is defined as “U.S. Patent No. 5,133,375 and corresponding foreign patents or applications and including divisions, reissues, continuations, renewals, and extensions thereof.” Id.
