This case is one of those non-patent patent cases that, as we explain more fully below, falls within the jurisdiction of the regional courts of appeals rather than the Federal Circuit. See 28 U.S.C. §§ 1295(a)(1), 1338;
Holmes Group, Inc. v. Vornado Air Circulation Sys., Inc.,
I
County Materials is in the business of manufacturing concrete blocks. Allan Block develops, markets, and licenses technology for the manufacturing of concrete blocks; it does not manufacture blocks itself. In April 1993, County Materials’s predecessor in interest, County Concrete Corporation, entered into a production agreement with Allan Block. The Agreement granted to County Materials the exclusive right to manufacture Allan Block’s patented block products in northwest Wisconsin. County also was granted the right to sell these products under the Allan Block trademark. Finally, Allan Block agreed to provide County Materials with significant technical, marketing, and strategic support while the Agreement was in effect.
The Agreement included a limited covenant not to compete, which allowed County Materials to make and sell two specific competing block products, without any time restrictions. The non-compete provision also required that for the 18 months following the termination of the Agreement, County Materials could not “directly or indirectly engage in the manufacture and/or sale of any other [competing] ... block.”
In 2005, Allan Block notified County Materials that it would be terminating the Agreement. Shortly thereafter, County Materials completed its own design for a new concrete block that would compete directly with the Allan Block products that it had been manufacturing and selling in northwest Wisconsin. As County Materials took steps to begin producing this new block, Allan Block threatened that it would sue to enforce the non-compete provision from the terminated Agreement. County Materials decided to move first, and so it filed this suit alleging that the inclusion of the non-compete provision in the Agreement constituted patent misuse, which made the Agreement void.

The district court’s jurisdiction over this case was based on diversity. 28 U.S.C. § 1332(a)(1). County Materials is a Wisconsin corporation with its principal place of business in Wisconsin; Allan Block is a Minnesota corporation with its principal place of business in Minnesota, and County Materials alleges damages exceeding $75,000.
Even though the requirements of § 1332 are therefore satisfied, there is a second potential jurisdictional hurdle in our path. Allan Block, repeating an argument made to this court in advance of oral argument, contends that appellate jurisdiction over this appeal lies with the Federal Circuit and not this court. The Supreme Court has held that the Federal Circuit has appellate jurisdiction
only [in] those cases in which a well-pleaded complaint establishes either that federal patent law creates the cause of action or that the plaintiffs right to relief necessarily depends on resolution of a substantial question of federal patent law, in that patent law is a necessary element of one of the well-pleaded claims.
Christianson v. Colt Indus. Operating Corp.,
Looking as we must at the well-pleaded complaint, it is apparent that federal patent law does not create the cause of action here. It is instead a claim about
*734
the enforceability of a contract or license agreement. Resolution of this appeal does not “necessarily require! ] resolution of substantial questions of federal patent law,” as Allan Block claims. We faced almost the same arguments in
Scheiber v. Dolby Laboratories, Inc.,
Federal jurisdiction over the suit is based on diversity of citizenship, because a suit to enforce a patent licensing agreement does not arise under federal patent law. E.g., Jim Arnold Corp. v. Hydrotech Sys., Inc.,109 F.3d 1567 , 1575 (Fed.Cir.1997). The presence of a federal defense (here, patent misuse) is irrelevant to jurisdiction. Christianson v. Colt Industries Operating Corp.,486 U.S. 800 ,108 S.Ct. 2166 ,100 L.Ed.2d 811 (1988).

This court reviews a district court’s decision to grant summary judgment
de novo. Balderston v. Fairbanks Morse Engine Div. of Coltec Indus.,
If a practice is not per se unlawful nor specifically excluded from a misuse analysis by § 271(d)
a court must determine if that practice is reasonably within the patent grant, i.e., that it relates to subject matter within the scope of the patent claims. If so, the practice does not have the effect of broadening the scope of the patent claims and thus cannot constitute patent misuse. If, on the other hand, the practice has the effect of extending the pat-entee’s statutory rights and does so with an anti-competitive effect, that practice must then be analyzed in accordance with the rule of reason. Under the rule of reason, the finder of fact must decide whether the questioned practice imposes an unreasonable restraint on competition, taking- into account a variety of factors, including specific information about the relevant business, its condition before and after the restraint was imposed, and the restraint’s history, nature, and effect.
Id. (internal citations and quotation marks omitted).
County Materials is not claiming that Allan Block was trying to extend the term of its patent by requiring post-expiration royalties. It is wrong, therefore, to argue that some form of
per se
analysis applies here. (By the same token, we have no need to explore further the question whether it makes any economic sense to treat these arrangements so harshly. See
Scheiber,
As County Materials recognizes, it is essentially making a leveraging argument. It argues both that “[ljeverage is presumed” and that there is a “proper method to conclude whether patent leverage was used.” Whatever else one might say about leveraging theory (which as we noted in
Scheiber
has been criticized in academic circles), however, there is no doubt that there is nothing “presumed” about it outside the narrow confines of post-expiration royalties. In
Brulótte,
the Supreme Court held that there are both proper and improper uses of patent leverage. It acknowledged that “[a] patent empowers the owner to exact royalties as high as he can negotiate
with the leverage of that monopoly
[, b]ut to use that leverage to project those royalty payments beyond the life of the patent is analogous to an effort to enlarge the monopoly of the patent.”
The Federal Circuit’s decision in
Windsurfing Int’l, Inc. v. AMF, Inc.,
Most of the cases on which County Materials relies come from an era before the Supreme Court recognized the efficiencies that might flow from vertical restrictions, which is the type of restriction we have when a patent owner (which does not compete in the manufacturing sector) imposes restraints on a manufacturing licensee. See generally
Leegin Creative Leather Prods., Inc. v. PSKS, Inc.,
— U.S. -,
Anticompetitive effects, in short, are a critical element of any patent misuse case that is evaluated under a rule of reason approach.
Windsurfing
was one of the first cases to recognize this; it required “a factual determination [that] ... reveal[s] that the overall effect of the license
tends to
restrain competition unlawfully in an appropriately defined relevant market.”
With these principles in mind, we are ready to assess County Materials’s case. To begin with, the Agreement between County Materials and Allan Block shows *737 no sign of one-sidedness or abuse of power on Allan Block’s part. County Materials received significant benefits, starting with the right to use the patented technology for the manufacture of the concrete blocks, and continuing with the right to use Allan Block’s trademark and the right to receive supporting technical, marketing, and strategic services from Allan Block. In return, County Materials had to promise to pay royalties to Allan Block and to devote significant efforts to the exploitation of Allan Block’s patent. If County Materials had been free to pick and choose among all potentially competing products on the market, Allan Block may have signed over the rights to use its patent and know-how for little or nothing in return. Allan Block’s services alone have considerable value for any company undertaking the manufacture and sale of these products (or so the parties could have concluded), whether or not they are tied to a patented product. Nothing in these facts suggests that Allan Block needed or used any kind of leverage made possible by the patent to secure County Materials’s promise to refrain from working with all but the designated two competing products, or its promise to refrain from using other products for 18 months after the expiration of the Agreement.
In fact, this was not a particularly onerous covenant not to compete. It allowed County Materials to continue to manufacture and sell not one but two competing products, which the district court reasoned would “guarantee plaintiff could always compete with defendant in the landscape block market.” In addition, the clause had both temporal and geographical limits. It lasted for only 18 months after the Agreement’s termination (a period which no one contends goes beyond the duration of Allan Block’s patent) and applied only to County Materials’s exclusive production territory, which was a section of Wisconsin. Although the non-compete clause may have hurt
County Materials’s
ability to compete as aggressively as it would have liked in the concrete block market in northwest Wisconsin, there does not appear to be any evidence in the record showing that these limited requirements have hurt
competition
for cement blocks in County Materials’s former exclusive territory. In the related field of antitrust, the Supreme Court has said that “[i]t is axiomatic that the antitrust laws were passed for the protection of competition, not competitors.”

Even if its patent misuse argument fails, County Materials maintains that the covenant not to compete violates' general principles of Minnesota law, which applies here. Minnesota courts look to three factors in evaluating this kind of clause: it must (1) protect a legitimate interest of the party in whose favor it is imposed, (2) be reasonable as between the parties, and (3) not be injurious to the public.
Haynes v. Monson,
As for the first factor, we are satisfied that Allan Block had a legitimate interest in the other resources and intangi
*738
bles that it gave to County Materials as part of the Agreement. “Legitimate interests that may be protected include a company’s ‘goodwill, trade secrets, and confidential information.’ ”
Medtronic, Inc. v. Advanced Bionics Corp.,
I made several person[al] trips over to the [County Materials] Eau Clame facility.... There were numerous phone calls over the 12- or 13-year history of us working together, everything from mix. design to actual issues, making the product. I was at the Eau Claire facility when they initially produced the first block. I assisted with the molds and other issues, training their staff on the differences between the different products and the configurations of the molds.
Bott also testified specifically as to the engineering support given to County Materials:
We provide a service that’s both formal and informal. The formal service allows for someone to have us prepare preliminary designs, working with the local engineer to assist in the facilitation ... of [County Materials] ... landing a project that requires engineering. We work with the engineers that locally will review and do the final design, to educate them on the subject matter. This product concept and this design concept ... is relatively new, and so most engineers have little or no education relative to this.
(emphasis added). None of this testimony has been disputed. The record shows that Allan Block had a legitimate interest in the resources and support that it gave to County Materials during their 12-year relationship.
The second factor is whether the agreement is reasonable as between the parties. Minnesota courts require that non-compete agreements not be greater than necessary to protect the legitimate business interest.
Dynamic Air, Inc. v. Bloch,
Further, when a licensee gets an exclusive patent license, as County Materials did here, it is benefitting from the paten-tee’s property rights more than it would with a non-exclusive license. The licensee reaps the rewards of the patent up to the bounds of its exclusivity. Given this additional benefit, it seems only fair that the licensee can be assigned part of the responsibility of promoting the product in the broader market. Under a clause like this, the licensee has a stake in ensuring the success of the product. If the granting of an exclusive license is not itself a restraint on trade (as it is not, and no one in this case alleges otherwise), then requiring as a condition of that license that the licensee not undermine the value of the bargain is not unreasonable either.
The final factor is that the challenged restraint must not be injurious to the public. Because covenants not to compete are not categorically prohibited by Minnesota law, it must be the case that such a clause would not be deemed injurious to the public unless some particular harm was alleged. Minnesota courts have upheld non-compete provisions in markets where multiple producers of like goods are present, reasoning that the general public is not injured by a non-compete agreement because competition in the relevant market is healthy.
Bess v. Bothman,
Y
Finally, County Materials argues that the district court abused its discretion in denying its motion to unseal portions of the record. A district court’s decision to seal portions of the record is reviewed for abuse of discretion.
Seattle Times Co. v. Rhinehart,
[protective orders entered during discovery in civil cases have ... justification ... and ... limits. Confidentiality while information is being gathered not only protects trade secrets but also promotes disclosure: parties having arguable grounds to resist discovery are more likely to turn over their information if they know that the audience is limited and the court will entertain arguments focused on vital knowledge that a party wants to use later.... Information that is used at trial or otherwise becomes the basis of decision enters the public record. ... Secrecy persists only if the court does not use the information to reach a decision on the merits.
In re Krynicki,
*740
We have held that “the public at large pays for the courts and therefore has an interest in what goes on at all stages of a judicial proceeding^ but t]hat interest does not always trump the property and privacy interests of the litigants.”
Citizens First Nat’l Bank v. Cincinnati Ins. Co.,
[t]here is no objection to an order that allows the parties to keep their trade secrets (or some other properly demarcated category of legitimately confidential information) out of the public record, provided the judge (1) satisfies himself that the parties know what a trade secret is and are acting in good faith in deciding which parts of the record are trade secrets and (2) makes explicit that either party and any interested member of the public can challenge the secreting of particular documents.
Id. at 946. The district court gave Allan Block a limited ability to keep under seal certain confidential documents, including transcripts of certain Allan Block employees and a few papers. Even though the district court may have acted too quickly when it summarily rejected County Materials’s motion to unseal the documents, at this point in the case it is County Materials’s burden to show how this prejudiced it. It has not done so. Rather than pointing to particular documents and explaining why they should have been unsealed, County Materials has argued instead that everything should have been unsealed. In fact, the district court did unseal portions of the sealed documents, including everything on which it relied in its opinion. Without more information from County Materials, we are not in a position to say either that the court abused its discretion by failing to unseal more or that County Materials was prejudiced by the court’s actions.
The judgment of the district court is Affirmed.
