Central Purchasing, LLC (“Central”), appeals the judgment of the United States District Court for the Northern District of Illinois, granting summary judgment of infringement of U.S. Patent No. 4,743,902 (“'902 patent”) in favor of Mitutoyo Corporation and Hexagon Metrology Nordic AB (collectively “Mitutoyo”), and awarding damages using a 29.2% royalty rate and including sales of the alleged infringing goods by both Central and Harbor Freight Tools USA, Inc. (“HFTUSA”), in the royаlty base.
Mitutoyo Corp. v. Central Purchasing, LLC,
No. 03-CV-990,
Background
Mitutoyo owns the '902 patent, which recites a device for electronically measuring the movement of one object in relation to another, e.g., the movement of a caliper’s slide relative to its scale. On February 10, 2003, Mitutoyu and MAC filed suit against Central for patent infringement and breach of contract. They alleged that Central’s sale of digital calipers manufactured by Guanglu Measuring Instrument Company, Ltd, infringed the '902 patent, both literally and willfully, and breached their 1994 settlement agreement — which resolved a 1992 patent infringement dispute, also involving the '902 patent, and provided that Central would refrain from any future importation or sale of infringing products. Central counterclаimed for invalidity, unenforceability, and non-infringement. In 1995, however, Central had brought a declaratory judgment action against Mitutoyo, alleging that the '902 patent was invalid and unenforceable; and it lost. Accordingly, under principles of res judicata, the trial court granted summary judgment on validity and enforceability in favor of Mitutoyo; Central does not challenge this ruling.
With respect to infringement, the parties’ dispute turned only on whether the accused devices meet the “phase position identification” limitation of claim 1 of the '902 patent.
*
The parties stipulated to the
*1288
following construction of “phase position”: “The amount by which the received signal is displaced or shifted in time relative to a supply electrode signal. This is commonly referred to as ‘phase angle’ in the art.” Based on this claim construction and Central’s admissions, the trial court found that Central literally infringed, because its devices determined “phase angle” in accordance with claim 1.
Liability Order,
In light of the infringement finding, the trial court also found Central liable for breach of contract.

Next, the trial court found that MAC was not a proper party to the action, because it concluded that it lacked standing. Although MAC is the exclusive distributor of Mitutoyo products in the United States, Mitutoyo admitted that it allowed other parties, namely General Tool Corp., to sell products covered by the '902 patent in the United States. The trial court, therefore, concluded that MAC did not possess the exclusive right to sell in the United States under the '902 patent, as required to maintain licensee standing under
Ortho Pharmaceutical Corp. v. Genetics Institute, Inc.,
With respect to damages, the trial court found that Mitutoyo was not entitled to a lost profit award, either for infringement or breach of contract, because it failed to establish any market overlap between its goods and Central’s. Whereas Mitutoyo’s calipers retailed from $40.00 to $397.00 and have advanced functionality, Central’s calipers sold from $19.12 to $48.98 and have more basic features. Given these facts and Mitutoyo’s failure to introduce any direct evidence of market overlap, the
*1289
trial court accepted Central’s argument that its calipers were directed exclusively at “do-it-yourselfers” who, in the absence of its products, would have either purchased another low-end caliper or not purchased one at all.

Central appeals as to infringement and the royalty; Mitutoyo and MAC cross-appeal as to willful infringement, MAC’s standing, аnd lost profits. We have jurisdiction under 28 U.S.C. § 1295(a)(1).
Discussion
Beginning with infringement, we address each of the parties’ challenges in turn.
A. Infringement
We review the trial court’s grant of summary judgment of infringement
de novo. OddzOn Prods., Inc. v. Just Toys,
Central argues that it does nоt literally infringe because the signal recorded by the receiving electrode in its devices is a sinusoidal wave, whereas the signal generated by the supply electrode is a square wave. Because these waves cannot be directly compared to determine the phase angle between them, it argues that its accused devices do not satisfy the “phase position identification” limitation. This argument, however, is without merit, and is based on an impermissibly narrow understanding of what claim 1 and the stipulated claim construction embody.
Neither the stipulated claim construction nor the language of claim 1 require calculation of the phase angle by
direct
comparison of the supply signal and the received signal. Instead, they merely require the phase angle to be calculated based on some comparison of those two signals, even an indirect one. Therefore, a reference signal, generated by the same signal clock as the supply signal, and which has not undergone any phase shifting, provides an appropriate basis from which to calculate phasе angle based on a comparison between that reference signal and the received signal. Moreover, this understanding of the “phase position identification” limitation is consistent with the specification, which expressly provides for determination of the phase angle via an
*1290
indirect comparison of the supply signal and the received signal using a rеference signal. 902 patent, col. 5, II. 22-66; see
also Phillips v. AWH Corp.,
By Central’s own admission, its accused devices determine the phase angle by using a reference signal generated by the same clock as the supply signal, whiсh does not undergo any phase shifting, and comparing the reference signal to the received signal.
Liability Order,
B. Willful Infringement
We construe the trial court’s dismissal of Mitutoyo’s willful infringement claim as a dismissal for failure to state a claim under Rule 12(b)(6) of the Federal Rules of Civil Procedure and, alternatively, as a dismissal for failure to prosecute under Rule 41(b). Both grounds for dismissal are procedural issues, not pertaining to patent law, that we review under regional circuit law.
Bowling v. Hasbro, Inc.,
In its complaint, under its patent infringement count, Mitutoyo alleged:
10. The acts of infringement by Central Purchasing have occurred with full knowledge of U.S. Patent No. 4,743,902 and have been willful and deliberate, making this case exceptional within the meaning of the United States patent laws.
It further provided details about the declaratory judgment suit filed by Central in 1995, which sought to invalidate and render unenforceable the '902 patent, thereby establishing that Central had knowledge of the '902 patent prior to 2002. This is plainly more than sufficient to meet the requirements of Rule 8(a)(2) for pleading a willful infringement claim and avoid dismissal under Rule 12(b)(6).
Christensen v. County of Boone,
The trial court also abused its discretion by dismissing the willfulness claim for failure to prosecute under Rule 41(b). Indeed, nothing in Mitutoyo’s litigation
*1291
conduct evidenced an intent not to pursue its willful infringеment claim. The trial court relied heavily on the fact that Mitu-toyo did not move for summary judgment of willful infringement. However, because summary judgment is only appropriate where there are no genuine issues of material fact, Fed. R. Civ. Pro. 56(c), its failure to so move likely indicates its sense that issues of material fact exist, not an intent to abandon its willfulness claim.

C. MAC’S Standing
MAC’S standing is a question of law that we review
de novo. Consol. Edison Co. v. Richardson,
D. Damages
Whether a party may receive lost profits is a question of law that we review de novo.
Poly-Am., L.P. v. GSE Lining Tech., Inc.,
*1292
With respect to the royalties, we review the trial court’s determinations for erroneous conclusions of law, clearly erroneous factual findings, and clear errors of judgment amounting to an abuse of discretion.
Rite-Hite Corp. v. Kelley Co.,
Central’s challenge amounts to little more than an argument that the trial court should have placed more emphasis on the facts favoring a lower royalty rate, and fails to establish any clear error or abuse of discretion. It admits that its antiсipated profit margin was 70% and that Mitu-toyo’s profit margin was 29.2%. While the trial court could have looked to other figures in determining what Central would have been willing to pay and what Mitu-toyo would have required for a license, its use of these figures was not clearly erroneous. Moreover, the 29.2% figure is reasonable given the contentious history between these two parties.
See Applied Med. Res. Corp. v. U.S. Surgical Corp.,
With respect to the royalty base, however, the trial court committed clear error by including HFTUSA’s sales, rather than Central’s sales to HFTUSA. To begin, it provided no explanation as to why Central would have agreed to pay a royalty based on those sales. And contrary to Mitutoyo’s contention, the business relationship between HFTUSA and Central, without more, does not provide a sufficient justification for including HFTUSA’s sales in the base. In
