Before WOLLMAN, GIBSON, and COLLOTON, Circuit Judges.

WOLLMAN, Circuit Judge.

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 Schinzing (Schinzing) in 1987.

Schinzing filed a patent application with the United States Patent and Trademark Office (PTO) in August 1988 (the ’091 application). The PTO rejected Schinzing’s application as obvious in December 1988 and rejected amended applications as obvious in January 1989 and July 1989.

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 declaratory judgment of non-infringement and a judgment that Mid-State had not breached the license agreement. See Fed. R. Civ. P. 59(e). Mid-State appeals from the district court’s denial of its motion and from the district court’s conclusion that the ’375 patent was not invalid.

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, 535 U.S. 826, 829-31 (2002), which

makes clear that the Federal Circuit’s jurisdiction attaches when a plaintiff’s wellpleaded complaint asserts a claim arising under federal patent law, but not when the patent issue is raised for the first time in a defendant’s counterclaim. Because Schinzing’s complaint alleged no claims arising under federal patent law and the patent issues arise solely from Mid-State’s counterclaim, appellate jurisdiction properly lies with us. Cf. Telecom Tech. Servs. Inc. v. Rolm Co., 388 F.3d 820, 826 (11th Cir. 2004) (“Because the face of the complaint, here, addresses antitrust issues and patent infringement issues are only raised as counterclaims, the Federal Circuit determined that it did not have jurisdiction over the present case and transferred it to this court.”); E.I. Du Pont de Nemours & Co. v. Okuley, 344 F.3d 578, 583 n.3 (6th Cir. 2003) (noting that counterclaims cannot serve as the basis for Federal Circuit jurisdiction).

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., 86 F.3d 1113, 1123 (Fed. Cir. 1996) (“Invalidity is a complete defense to infringement and . . . .[n]o further public interest is served by our resolving an infringement question after a determination that the patent is invalid.”). Mid-State asserts four theories under which the district court should have invalidated the ’375 patent: (1) inventorship (because Schinzing failed to name the students as co-inventors); (2) prior publication (based on the student report); (3) public use (based on the student demonstration); and (4) inequitable conduct.

A.

The first step in any invalidity analysis is claim construction. Akamai Techs., Inc. v. Cable & Wireless Internet Servs., Inc., 344 F.3d 1186, 1192 (Fed. Cir. 2003). Construction of the claims by the trial court is often conducted upon a preliminary evidentiary hearing, called a Markman hearing (which derives its name from Markman v. Westview Instruments, Inc., 517 U.S. 370 (1996)). EMI Group North America, Inc. v. Intel Corp., 157 F.3d 887, 891-92 (Fed. Cir. 1998). A court is required to construe the limitations of the claims and apply them to the allegedly invalidating acts. See Dana Corp. v. American Axle & Mfg., Inc., 279 F.3d 1372, 1376 (Fed. Cir. 2002). See also Trovan, Ltd. v. Sokymat SA, Irori, 299 F.3d 1292, 1302 (Fed. Cir. 2002) (claim construction is the first step in invalidity analysis based on inventorship); Helifix Ltd. v. Blok-Lok, Ltd., 208 F.3d 1339, 1346 (Fed. Cir. 2000) (same with respect to prior publication); Bernhardt, L.L.C. v. Collezione Europa USA, Inc., 386 F.3d 1371, 1377 (Fed. Cir. 2004) (same with respect to public use).
