Zimmer Biomet Holdings, Inc. v. Insall, No. 23-1888 (7th Cir. 2024)

Annotate this Case

Dr. John Insall, an orthopedic surgeon, developed and patented knee replacement devices, which he licensed to Zimmer Biomet Holdings, Inc. In return, Zimmer agreed to pay royalties to Insall, and later to his estate after his death. When Insall’s last patent expired in 2018, Zimmer ceased royalty payments, claiming the obligation had ended. The dispute was submitted to arbitration, where the Estate prevailed. Zimmer then sought to vacate the arbitration award in district court, arguing that continuing royalty payments violated public policy. The district court confirmed the arbitration award.

The United States District Court for the Northern District of Illinois reviewed the case. Zimmer argued that the arbitration award should be vacated based on public policy grounds, citing Supreme Court decisions in Brulotte v. Thys Co. and Kimble v. Marvel Entertainment, LLC, which prohibit collecting royalties on expired patents. The district court rejected Zimmer’s argument and confirmed the arbitration award, leading to Zimmer’s appeal.

The United States Court of Appeals for the Seventh Circuit reviewed the case. The court emphasized the limited scope of judicial review over arbitration awards under the Federal Arbitration Act (FAA). The court found that the arbitration panel had correctly interpreted the 1998 amendments to the agreement, which untethered the royalty payments from the patents themselves, making them based on the marketing and branding of the NexGen Knee products. Consequently, the court held that the arbitration award did not violate public policy as outlined in Brulotte and Kimble. The Seventh Circuit affirmed the district court’s decision and confirmed the arbitration award in favor of Insall’s Estate.

In the United States Court of Appeals For the Seventh Circuit ____________________ No. 23-1888 ZIMMER BIOMET HOLDINGS, INC., Plaintiff-Appellant, v. MARY N. INSALL, as Executrix of the Estate of John N. Insall, Defendant-Appellee. ____________________ Appeal from the United States District Court for the Northern District of Illinois, Eastern Division. No. 1:22-cv-02575 — Lindsay C. Jenkins, Judge. ____________________ ARGUED JANUARY 19, 2024 — DECIDED JULY 12, 2024 ____________________ Before ST. EVE, LEE, and PRYOR, Circuit Judges. LEE, Circuit Judge. Dr. John Insall, an orthopedic surgeon who specialized in knee reconstruction and replacement, developed and obtained a number of valuable foreign and domestic patents involving knee replacement devices and accoutrements that he licensed to Zimmer Biomet Holdings, Inc. In exchange, Zimmer agreed to pay substantial royalties to Insall (which, upon his death, Zimmer paid to his Estate). After Insall’s last patent expired in 2018, Zimmer stopped all 2 No. 23-1888 royalty payments, asserting that its obligation under the royalty agreement had expired. The parties submitted the dispute to arbitration as required by the agreement, and the Estate prevailed. Zimmer then asked the district court to vacate the arbitration award, arguing that enforcement of the contract would violate public policy. The district court rejected this argument and con rmed the award. We agree and a rm. I. Factual Background As a medical device company, Zimmer manufactures a variety of products, including technology used for knee replacements. Zimmer joined forces with Insall in 1991 to develop certain knee replacement devices and related appurtenances ultimately sold under the brand name “NexGen.” Under this plan, Insall would develop and secure patents for these devices, and Zimmer would pay royalties to Insall for the right to license, market, and sell them. This arrangement was memorialized in a written agreement in 1991. It required Zimmer to make royalty payments to Insall until “the expiration of the last to expire of the patents licensed hereunder or so long as Product is sold by ZIMMER, whichever is last to occur.” The parties amended the agreement in 1994. Among other things, Insall promised to work exclusively for Zimmer through January 1, 2011. The parties also agreed to expand the scope of the agreement from the particular knee replacement system identi ed in the 1991 agreement to “the design and development of all components of any future knee system that is developed in whole or in part in the United States and o ered as a standard line product for Zimmer.” As for the royalty payments, they were to encompass Insall’s work on “future knee systems” until “the expiration of the last to expire of the Patents licensed hereunder or on January 1, 2011, No. 23-1888 3 whichever is last to occur.” The parties also added an arbitration provision that required all disputes arising out of or related to the agreement to be submitted for binding arbitration. Portions of the agreement were amended again in 1998. Relevant here, the amended agreement provided: The parties acknowledge that … royalties shall be paid at the rate of 1% of Net Sales Price on all sales of the NexGen Knee and all subsequently developed articles, devices or components marketed by Zimmer as part of the NexGen Knee family of knee components and not at the rate provided for sales of “future knee systems.” In a previous arbitration between the parties (referred to as the Persona Arbitration, named after the technology at issue in that dispute), Zimmer’s counsel explained that the 1998 amendments changed the method by which royalties were to be calculated. Rather than being based on the sale of products containing the patented technology, the royalties under the 1998 agreement were based on the sale of items that Zimmer marketed under its “NexGen Knee” family of products. The arbitration provision remained unchanged. Insall’s last patent expired on March 10, 2018, and Zimmer’s chief patent counsel informed the Estate a few months later that the company would no longer pay royalties to the Estate. By way of explanation, Zimmer asserted that under the Supreme Court decisions Brulotte v. Thys Co., 379 U.S. 29 (1964), and Kimble v. Marvel Entertainment, LLC, 576 U.S. 446 (2015), a licensor may not collect royalties based on an expired patent. In its view, the payment of ongoing royalties under 4 No. 23-1888 the amended agreement ran “counter to the policy and purpose of patent laws.” Unsurprisingly, the Estate disagreed, and the parties submitted the dispute for arbitration in late 2019. In a detailed decision, the arbitration panel concluded that Brulotte did not render the royalty provision in the 1998 agreement void and unenforceable. As such, the panel found that Zimmer had breached its obligations to pay royalties to the Estate, ordered Zimmer to pay past-due royalties, and a rmed Zimmer’s obligation to pay royalties to the Estate in accordance with the 1998 agreement. Zimmer then initiated this lawsuit and asked the district court to vacate the award. The Estate responded with a motion to dismiss and moved the district court to con rm the arbitration award. The district court agreed with the Estate and con rmed the arbitration award. This appeal followed. II. Scope of Review A. Standard of Review We review a district court’s decision on a motion to vacate or con rm an arbitration award under the Federal Arbitration Act (FAA) de novo. Webster v. A.T. Kearney, Inc., 507 F.3d 568, 571 (7th Cir. 2007). Factual ndings are reviewed for clear error. Kinsella v. Baker Hughes Oil eld Operations, LLC, 66 F.4th 1099, 1103 (7th Cir. 2023). We begin by emphasizing that the FAA and Supreme Court precedent establish that “arbitration awards are largely immune from … scrutiny in court.” Nano Gas Techs., Inc. v. Roe, 31 F.4th 1028, 1031 (7th Cir. 2022) (cleaned up). The breadth of our review is “extremely limited.” Chrysler Motors Corp. v. Int’l Union, Allied Indus. Workers of Am., AFL-CIO, 959 No. 23-1888 5 F.2d 685, 687 (7th Cir. 1992). We may not reconsider the merits of an award even when a party argues that the arbitrators made a factual error or even a legal one when interpreting a contract. United Paperworkers Int’l Union, AFL-CIO v. Misco, Inc., 484 U.S. 29, 36 (1987). There is, however, a narrow exception to our tightly proscribed review. As discussed more below, “[t]he public policy doctrine allows this court to decide de novo whether [the award at issue] violates public policy.” Chrysler Motors, 959 F.2d at 687 (cleaned up). B. The Federal Arbitration Act Arbitration aims to resolve disputes more e ciently and at a lower cost than traditional litigation. See Sarah Rudolph Cole, Curbing the Runaway Arbitrator in Commercial Arbitration: Making Exceeding the Powers Count, 68 Ala. L. Rev. 179, 184 (2016). In exchange for expediency and nality, however, parties trade the right to challenge the substance of the decisionmaker’s ruling; as a result, judicial review of arbitral awards is extremely limited and highly deferential. See A ymax, Inc. v. Ortho-McNeil-Janssen Pharms., Inc., 660 F.3d 281, 285 (7th Cir. 2011) (citing Major League Baseball Players Ass’n v. Garvey, 532 U.S. 504 (2001)). The FAA authorizes a court to vacate an award for only four reasons: (1) where the award was procured by corruption, fraud, or undue means; (2) where there was evident partiality or corruption in the arbitrators, or either of them; 6 No. 23-1888 (3) where the arbitrators were guilty of misconduct in refusing to postpone the hearing, upon su cient cause shown, or in refusing to hear evidence pertinent and material to the controversy; or of any other misbehavior by which the rights of any party have been prejudiced; or (4) where the arbitrators exceeded their powers, or so imperfectly executed them that a mutual, nal, and de nite award upon the subject matter submitted was not made. 9 U.S.C. § 10(a). Congress statutorily constrained the grounds for vacatur to these reasons, and courts may not expand them. Hall Street Associates, L.L.C. v. Mattel, Inc., 552 U.S. 576, 584–89 (2008) (noting also that limited judicial review of arbitration awards is “needed to maintain arbitration’s essential virtue of resolving disputes straightaway”). Furthermore, Section 10(a) has been understood to re ect a congressional focus on procedural protections rather than ensuring the correct outcome. See Dean Witter Reynolds, Inc. v. Byrd, 470 U.S. 213, 219 (1985) (“The legislative history of the Act establishes that the purpose behind its passage was to ensure judicial enforcement of privately made agreements to arbitrate.”); see Hill v. Norfolk & Western Ry., 814 F.2d 1192, 1194–95 (7th Cir. 1987) (the question before us “is not whether the arbitrator or arbitrators erred in interpreting the contract; it is not whether they clearly erred in interpreting the contract; it is not whether they grossly erred in interpreting the contract; it is whether they interpreted the contract”). No. 23-1888 7 C. Public Policy Exception That said, the power of federal courts to enforce contracts is at all times “subject to the restrictions and limitations of the public policy of the United States as manifested in the Constitution, treaties, federal statutes, and applicable legal precedents.” Hurd v. Hodge, 334 U.S. 24, 35 (1948). And where enforcement of private agreements would violate public policy, “it is the obligation of courts to refrain from such exertions of judicial power.” Id. The Supreme Court has explicitly applied this principle to agreements to arbitrate. In doing so, the Court has been clear that if a contract—as interpreted by the arbitrators—and the accompanying remedy or relief violate some explicit public policy, “we are obliged to refrain from enforcing” the arbitration award. W.R. Grace & Co. v. Loc. Union 759, Int’l Union of United Rubber, Cork, Linoleum & Plastic Workers of Am., 461 U.S. 757, 766 (1983). Not any policy will do, however. To trigger this exception, a policy “must be well de ned and dominant, and is to be ascertained by reference to the laws and legal precedents and not from general considerations of supposed public interests.” Chrysler Motors, 959 F.2d at 687 (cleaned up). Despite our limited authority to review arbitration awards, then, “[t]he question of public policy is ultimately one for resolution by the courts.” W.R. Grace, 461 U.S. at 766. Here, Zimmer invokes this exception, arguing that the arbitration panel’s interpretation of the agreement and resulting award of royalties must be voided as a matter of public policy. Before proceeding, however, we need to address the Estate’s threshold contention that the public policy exception to the enforcement of arbitration awards is limited to disputes involving collective bargaining agreements. While this issue 8 No. 23-1888 certainly arises regularly in those types of cases, we have never cabined the doctrine to the arbitration of labor disputes. Indeed, we have considered the public policy exception to the enforcement of arbitration awards in other contexts. See, e.g., In re Harshaw, 26 F.4th 768, 775 (7th Cir. 2022). And this makes sense given that the doctrine “derives from the basic notion that no court will lend its aid to one who founds a cause of action upon an immoral or illegal act.” United Paperworkers Int’l Union, 484 U.S. at 42; see also W.R. Grace, 461 U.S. at 766 (“As with any contract, however, a court may not enforce a collective bargaining agreement that is contrary to public policy.”) (emphasis added). Thus, neither precedent nor the FAA supports the Estate’s view that the public policy exception can apply only to arbitration awards in labor disputes. With that, we proceed to the main topic at hand. III. Analysis A. The Arbitration Award On appeal, Zimmer urges us to vacate the arbitration award because it violates the public policy the Supreme Court laid out in Brulotte and Kimble. In evaluating whether an arbitration award violates public policy, we are bound by the arbitrators’ interpretation of the contract. W.R. Grace, 461 U.S. at 766. As such, we examine the interpretive questions put to the arbitration panel and the panel’s conclusions. We then ask whether the contract—as interpreted by the arbitration panel—and the arbitration award violate public policy. But rst we examine Brulotte and Kimble. In Brulotte, the plainti owned several patents for certain hop-picking machines. 379 U.S. 29, 29–30 (1964). He manufactured the machines and sold them to farmers, along with No. 23-1888 9 licenses to use them. In return, the farmers agreed to pay the plainti royalties from the crops they harvested during the life of the license agreements. The patents, however, expired before the end date of the agreements, and the farmers refused to make any royalty payments on the grounds that the plainti had misused the patents by requiring royalties after their expiration. In the end, the Supreme Court agreed, holding that the license agreements were unenforceable and “unlawful per se” to the extent they provided for the payment of royalties “accru[ing] after the last of the patents incorporated into the machines had expired.” Id. at 30, 32. Over the years, the reasoning in Brulotte has faced much criticism from courts and academics alike. See Scheiber v. Dolby Lab’ys, Inc., 293 F.3d 1014, 1017–18 (7th Cir. 2002) (reviewing the cases and academic writings critical of Brulotte). And we took part in the growing chorus. Id. at 1017 (noting that Brulotte has been “severely, and as it seems to us, with all due respect, justly, criticized”). This was the landscape the Supreme Court encountered when it contemplated overruling Brulotte in Kimble. In that case, the inventor Kimble had obtained a patent on a toy that children used to shoot web-like foam string to roleplay as “a spider-person” (this is the word the patent used). Not surprisingly, Marvel Entertainment, LLC (the publisher of the Spider-Man graphic novels and owner of the mark) was none too happy. It sued Kimble, and the parties eventually entered into a settlement agreement. In it, Marvel agreed to purchase the patent from Kimble in exchange for a lump sum and a three percent royalty on future sales of the toy, with no termination date. 10 No. 23-1888 As the patent’s expiration approached, Marvel sought a declaratory judgment that it could stop making the royalty payments to Kimble once the patent became inviable, relying on Brulotte. In response, citing the criticism of Brulotte, Kimble asked that Brulotte be overruled. The Supreme Court, however, did not nd Kimble’s criticism of Brulotte on economic e ciency grounds particularly persuasive, noting that contracting parties “can often nd ways around Brulotte to achieve those same ends.” Kimble, 576 U.S. at 453. On the other hand, the Court stated, the important aims of stare decisis counseled upholding Brulotte, and to the extent that Kimble disagreed with its holding as a matter of policy, he was better o addressing his complaints to Congress. Signi cantly, however, the Supreme Court took the opportunity to clarify Brulotte’s scope. First, it observed that “all the decision [i.e., Brulotte] bars are royalties for using an invention after it has moved into the public domain.” Id. at 453– 54. Second, it explained that, even under Brulotte, “post-expiration royalties are allowable so long as tied to a non-patent right—even when closely related to a patent.” Id. at 454. What does this mean for our case? In the arbitration, Zimmer argued that it need not pay any royalties to Insall’s Estate because the basis for the royalties—the patents—had expired. But this argument presupposes that the royalties were, in fact, based on the rights the patents bestowed and not some “nonpatent right” that is “closely related to” the patents. Thus, the main question the arbitration panel had to decide is whether the royalties Zimmer promised in the agreement and its amendments were based on the patents themselves or a closely related non-patent right. No. 23-1888 11 Tackling this head-on, the arbitrators examined and interpreted each iteration of the contract. The panel rst agreed with Zimmer that Brulotte applied to the royalty provision in the 1991 agreement. But the panel went on to nd that the 1998 amendments created a di erent royalty regime: What the parties contemplated in 1991 and Dr. Insall’s imputed leverage were superseded by events and a new basis for determining royalties in 1998, as Zimmer strenuously and successfully maintained in the Persona Arbitration. Article IV’s Royalties provision from 1991 was not deleted (cf., 1998 Secs. 3 and 11). Under 1998 Sec. 3, however, it became vestigial, replaced by a new royalty provision untied and no longer dependent on Insall’s patents, products, or technology. The 1998 Agreement text separates Insall’s royalty rights from anything based on patents or technology. Zimmer obtained the new royalty provision it sought superseding the 1991 “hybrid” license. Nothing remained that mixed patent/non-patent royalties. (emphasis provided). Along the way, it relied on statements by Zimmer’s own witnesses in the Persona Arbitration as well as Zimmer’s counsel, who stated in his closing argument that the 1998 amendment “changed the structure, changed the royalty payment determination from one based on products having Insall’s technology in them as it was in ’91 and ’94 to a[n] [sic] is it marketed based as [sic] NexGen determination.” The royalty in the 1998 amendments, counsel continued, became “a marketing and branding based determination” and gave 12 No. 23-1888 Insall “royalty on components he doesn’t have any technology in or any involvement in.” On appeal, Zimmer disagrees with the arbitration panel’s conclusions and argues that, although the parties changed how the royalties were calculated, they never changed why they were paid in the rst place. But we are not here to judge whether the panel’s determination was correct. As we have recently emphasized, “[a]n arbitration clause delegates interpretive power to the arbitrators. We do not ask whether they read the contractual language correctly; it is enough that they tried to apply the contract that the parties signed.” Am. Zurich Ins. Co. v. Sun Holdings, Inc., 103 F.4th 475, 477 (7th Cir. 2024). Here, whether the 1998 amendment untethered the royalties from the patents was a question of interpretation reserved for the arbitrators. See United Steelworkers of Am. v. Enter. Wheel & Car Corp., 363 U.S. 593, 599 (1960). And, after examining the agreement and its amendments, the arbitration panel’s conclusion was clear—the 1998 amendments controlled, and the royalty terms were no longer premised on the patents or the technology they covered. Our only remaining task, then, is to decide whether the royalty provision in the 1998 agreement, as the arbitration panel construed it, violates a well-de ned and dominant public policy. B. Well-De ned and Dominant Public Policy Despite the deference arbitral decisions demand, we nevertheless must vacate an arbitration award if the remedy or relief violates an explicit, well-de ned, and dominant public policy. W.R. Grace, 461 U.S. at 766. Whether a policy meets those criteria must be decided based on “laws and legal No. 23-1888 13 precedents and not from general considerations of supposed public interests.” Muschany v. United States, 324 U.S. 49, 66 (1945). An arbitral award most clearly violates public policy when it creates an explicit con ict with statutory laws or wellestablished and easily discernible precedent. Titan Tire Corp. of Freeport v. United Steel, Paper & Forestry, Rubber, Mfg., Energy, Allied Indus. & Serv. Workers Int’l Union, 734 F.3d 708, 716 (7th Cir. 2013) (“A violation of a statute or some other positive law is the clearest example of a violation of public policy and no arbitrator is entitled to direct a violation of positive law.”) (cleaned up). Zimmer contends that Brulotte and Kimble established a dominant and well-de ned public policy that a party may not be compensated for patent rights after the patent’s expiration. But we need not decide this question, because the arbitration award here must be con rmed even if Zimmer’s assessment is correct. Assuming, for argument’s sake, that Brulotte and Kimble announced a clear public policy that royalties tied to patent rights are unenforceable after the patent’s expiration, Zimmer has no path to victory. After interpreting the parties’ license agreement and its amendments, the panel determined that the royalty payments in question were not grounded in any patent rights and, thus, did not o end Brulotte and Kimble. We have no power to unwind that holding here. IV. Conclusion For these reasons, we AFFIRM the district court and con rm the arbitration award in favor of Insall’s Estate.
