By Kevin E. Noonan –

In addition to the briefs from the parties, seventeen amicus briefs were filed with the Supreme Court in Hikma v. Amarin: six in favor of Petitioner Hikma, seven in favor of Respondent Amarin, and the remaining five on behalf of neither party (although the latter category is in some instances shaded by underlying biases). Synopses of the briefs in favor of Hikma are provided in this post. Subsequent posts will provide synopses of the briefs in favor of Amarin and those favoring neither party.
76 Scholars* in Law, Business, Economics, and Medicine
The Scholars’ principal argument is that inducement requires “an act that is specific, unambiguous, and affirmative,” citing Glob.-Tech Appliances, Inc. v. SEB SA, 563 U.S. 754, 766 (2011), and Hewlett-Packard Co. v. Bausch & Lomb Inc., 909 F.2d1464, 1469 (Fed. Cir. 1990). “Conduct that (1) does not specifically encourage infringement, (2) is ambiguous as to infringing or noninfringing behavior, or (3) is an omission has long been insufficient for patent inducement liability” the brief asserts, accusing the Federal Circuit of “disregard[ing] these principles,” wherein “inducement liability could arise based on speculative inferences from general marketing statements and mandatory drug labeling text—statements that bore no specificity to the patented methods of use at issue,” consistent with the Court’s decision (erroneous in the Scholars’ view) with GlaxoSmithKline LLC v. Teva Pharmaceuticals USA.
These instances are both errors of law and “threaten[] the statutory scheme for generic drug competition, the innovation economy, the patent system’s foundational principles, and patient health and welfare” in the Scholars’ view.
Much of the Scholars’ arguments are consistent with Hikma and other amici, that the Federal Circuit’s decision is contrary to the Congressional scheme under the Hatch Waxman Act to promote generic competition in pharmaceutical products (although there is much less discussion of Congress’s attempt to promote balance between innovator and generic drugmakers). They also raise a concern (shared in Hikma’s brief and by other amici) that the decision will raise the specter of inducement liability that could chill if not stifle drug competition, made worse by the Federal Circuit’s use of statements required by law (on the label) in support of inducement.
The Scholars posit that the failure of Congress to set forth guidelines and “mechanisms” for determining the standards for inducement in the skinny label context was evidence of “congressional understanding that avoidance of patent inducement is a simple, clear, easily determined matter.”
Doctrinally, the Scholars set forth three requirements for establishing inducement: specific actions, lacking ambiguity, and affirmative acts of commission. The need for the specific prong of the active inducement standard in the brief is supported in caselaw by A. Stucki Co. v. Worthington Indus., Inc., 849 F.2d 593, 597 (Fed. Cir. 1988); Warner-Lambert Co. v. Apotex Corp., 316 F.3d 1348, 1364 (Fed. Cir. 2003); Vita-Mix Corp. v. Basic Holding, Inc., 581 F.3d 1317, 1329 n.2 (Fed. Cir. 2009); DSU Med. Corp. v. JMS Co., Ltd., 471 F.3d 1293, 1306 (Fed. Cir. 2006) (en banc); Tegal Corp. v. Tokyo Electron Co., Ltd., 248 F.3d 1376, 1379 (Fed. Cir. 2001).
The Scholars’ support for the “lack of ambiguity” requirement is supported by Takeda Pharms. U.S.A., Inc. v. W.-Ward Pharm. Corp., 785 F.3d 625, 632 (Fed. Cir. 2015); C.R. Bard, Inc. v. Advanced Cardiovascular Sys., 911 F.2d 670, 675 (Fed. Cir. 1990); HZNP Meds. LLC v. Actavis Lab’ys UT, Inc., 940 F.3d 680, 702 (Fed. Cir. 2019); Eli Lilly & Co. v. Bd. of Regents, 334 F.3d 1264, 1369 (Fed. Cir. 2003).
Finally, the Scholars support for the affirmative “act of commission” requirement finds support in Beverly Hills Fan Co. v. Royal Sovereign Corp., 21 F.3d 1558, 1568 (Fed. Cir. 1994); Global-Tech, 563 U.S. at 760; and Tegal, 248 F.3d at 1378.
More generally, the Scholars cite a century and a half of precedent on the standards for inducement of infringement, namely Wallace v. Holmes, 29 F. Cas. 74, 80 (C.C.D. Conn. 1871); Motion Picture Pats. Co. v. Universal Film Mfg. Co., 243 U.S. 502, 516 (1917) (overruling Henry v. A.B. Dick Co., 224 U.S. 1 (1912); Carbice Corp. of Am. v. Am. Pats. Dev. Corp., 283 U.S. 27, 32 (1931); and G.S. Rich in Infringement Under Section 271 of the Patent Act of 1952, 21 Geo. Wash. L. Rev. 521, 542 (1953).
The remainder of the brief sets forth arguments regarding drug policy and the deleterious effects on drug pricing and innovation that will accrue should the Federal Circuit’s decision be permitted to stand.

Shashank Upadhye
The argument set forth by this amicus is that the conduct was lawful and liability depends solely on Hikma’s intent, which amicus does not believe was sufficiently established. The brief focuses on the proper application of Bell Atlantic Corp. v. Twombly, 550 U.S. 544 (2007), and Ashcroft v. Iqbal, 556 U.S. 662 (2009), and that these decisions “permit heightened specificity” in this instance. Inducement as defined by this amicus is “not negligence,” “not strict liability,” “not mere foreseeability” but rather “[i]It is a doctrine of purposeful encouragement” for direct infringement based on the same caselaw (Global-Tech Appliances, Inc. v. SEB S.A., 563 U.S. 754, 766 (2011); Commil USA, LLC v. Cisco Sys., Inc., 575 U.S. 632, 642 (2015); Metro-Goldwyn-Mayer Studios Inc. v. Grokster, Ltd., 545 U.S. 913, 937 (2005)) cited by others. Inducement cannot be promised solely on lawful conduct this amicus contends, citing Warner-Lambert Co. v. Apotex Corp., 316 F.3d 1348, 1364 (Fed. Cir. 2003).
The question identified here is “a distinct procedural question: what level of factual specificity is required at the pleading stage when inducement is alleged based on conduct that Congress has affirmatively authorized”? It cannot be the skinny label itself (nor designation as a generic or a therapeutic equivalent rating) but must be “something more.” As an indication of what such something more can be, the brief asserts that “when intent is the sole element transforming statutorily authorized conduct into alleged wrongdoing, the pleading burden carries unusual institutional significance.” Amicus uses Grokster* as illustrative: “inducement liability arose not from neutral instructions or product descriptions, but from an integrated course of conduct designed to foster infringement.”
If the “underlying conduct” is lawful, and liability depends entirely on proving purposeful encouragement beyond that conduct, then plausibility demands concrete factual content, not inference built upon inference, amicus argues, and “when an inducement claim rests primarily on legal conduct Congress has authorized, the complaint must plead with particularity the objective facts that render specific intent plausible by identifying the acts of encouragement, the audience targeted, the connection to the claimed method, and a plausible causal pathway to infringement.” These arguments are consistent with arguments from other amici that inducement requires “purposeful, culpable encouragement.”
*One difference, of course, is that inducement of infringement is not codified in any statute under Title 17, which might bring some pause to the Court when asked to use copyright principles/jurisprudence in coming to a conclusion here.
Association for Accessible Medicines
This amicus argues that offering a drug for sale does not induce infringement of carved-out method patent because Section viii only applies to methods for using an unpatented drug. Further, the brief asserts that unlike ANDA filings, Section viii does not trigger pre-launch infringement litigation because skinny labels per se do not themselves induce infringement. The existence of state automatic substitution laws inhibits generic drug companies from prescribing a specific manufacturer’s generic drug according to this amicus.
Amicus sets out the principal differences between ANDA litigation and the Section viii carve-out strategy to be:
[W]ith a skinny label, a generic can get on the market immediately—no litigation, no delays, and under a correct view of the law, no fear that the skinny label will induce infringement. The results have been spectacular—hundreds of generic drugs on the market sooner, with billions of dollars in savings.
The brief sets forth four errors or “fundamental” misunderstandings of the law by the Federal Circuit that provide a basis for the Court to reverse the judgement:
(1) Section viii applies only to method patents. The sale (or offer for sale) of an unpatented product cannot induce infringement of a patent that claims only one way of using that product.
(2) Skinny labels do not induce infringement of the carved-out patent. That is why the statute requires no notice to the brand and no pre-launch adjudication when the generic carves out the patent, whereas it does require notice and provides for pre-launch adjudication (and delayed FDA approval of the generic) when a generic challenges a patent as invalid.
(3) True statements that a generic product is the “generic version” or “generic equivalent” of a brand product merely echo what the government itself says; they are characterizations of the (unpatented) product, not the labeled uses.
(4) Generics generally do not market their products, because of state automatic-substitution laws, and because doctors do not specify which company’s generic product will be used to fill a prescription. Press releases directed to investors, not doctors, have no bearing on doctors’ prescribing decisions.
Active inducement requires affirmative encouragement and calling a drug “generic” or having a skinny label itself or press releases itself not enough. This amicus blames high drug costs on lack of competition, using arguments based mostly on a dire consequences scenario:
But if the Federal Circuit’s decision is not reversed, Section viii will plummet in significance. The Federal Circuit has opened the floodgates for litigation against generic manufacturers, allowing cases to get past the pleading stage merely by alleging conduct that is utterly commonplace in skinny-label launches.
Amicus further argues that that Congress enacted the skinny label regime knowing off-label infringement of the unpatented drug for a patented use would occur (at least under State automatic substitution laws):
Section viii reflects Congress’s judgment that patents on a specific use of an unpatented drug must not delay approval of a generic version of the drug itself, and its insight that removing the patented use from the label suffices to prevent inducement.
This amicus‘ argument came down to (in its view) that Hikma did what it was supposed to do under Section viii, and shared many of the same policy arguments asserted by other amici.
Henry A. Waxman
Not surprisingly, Congressman Waxman’s amicus brief describes in some detail the historical antecedents to Section viii as part of the Hatch-Waxman scheme for facilitating generic drug entry into the marketplace and the success the Act has had in the past forty years in achieving Congress’s aims in that regard. The brief asserts that the Congressman “believes both that the Federal Circuit’s decision in this case is flatly inconsistent with the language of the Act and congressional intent, and that unless overturned it will devastate the Hatch-Waxman Act’s generic drug program, which has saved patients, the federal government, and other payers trillions of dollars” (“nearly $3.4 trillion” over the past ten years” and later in the brief stating that “In 2024 generic drugs comprised 90% of prescriptions filled nationally, saving $447 billion, including $142 billion in Medicare savings and $62.1 billion in Medicaid savings”).
The principal benefit has been that branded drug makers can be incentivized to find new indications for drugs and at the same time generic drug makers can enter the marketplace for earlier-claimed indications as exclusivities and patents for the drug itself, stating that “section viii provides the mechanism for a generic company to identify those uses, so that a product with a label matching them can quickly come to market,” citing Caraco Pharm. Labs., Ltd. v. Novo Nordisk A/S, 566 U.S. 399, 415 (2012) (emphasis added); Takeda Pharm. U.S.A., Inc. v. West- Ward Pharm. Corp., 785 F.3d 625, 630 (Fed. Cir. 2015); Warner-Lambert Co. v. Apotex Corp., 316 F.3d 1348, 1360 (Fed. Cir. 2003) (emphasis in brief).
The brief cautions that “[c]ourts ‘must respect the role of the Legislature, and take care not to undo what it has done. A fair reading of legislation demands a fair understanding of the legislative plan,’” citing King v. Burwell, 576 U.S. 473, 498 (2015), and that the Federal Circuit rationale against Hikma in this case “ignores the legislative text and undermines Congress’s careful and considered ‘legislative plan.’” The brief further asserts that “Congress . . . anticipated this exact situation” in this case, that the Federal Circuit’s decision was “inconsistent [(i.e., cannot be reconciled)] with the statute” and “will have major adverse implications” should the decision be permitted to stand by the Court. These statements are particularly directed to the evidence considered by the lower court in determining that the question of infringement inducement should have survived Hikma’s motion to dismiss.
Public Citizen
This brief argues that Hikma “played by the [statutory] rules” and the Act does not “permit patent liability to be imposed on generic manufacturers who play by the rules when marketing drugs approved with skinny labels.” The arguments are particularly focused on “making medicines more affordable [by] the adoption of policies that facilitate regulatory approval and marketing of generic drugs that compete with expensive brand-name drugs.” The brief further states that “Public Citizen submits this brief to explain that the [Federal Circuit’s] opinion in the case disregards the language and structure of the Hatch-Waxman Amendments, is likely to cause significant harm to consumers, and runs counter to the strong federal policy of promoting the availability of generic medications as a means of lowering costs for patients” (which is exactly that it does in detail, reciting many of the arguments made by Hikma and other amici down to referring to certain of the evidence as comprising “anodyne” statements not supporting a conclusion of inducement to infringe). The brief concludes with policy arguments that the Federal Circuit’s decision “threaten[s] serious harm to the consumer-protection and public-health goals of the Hatch-Waxman Amendments,” supported by statistics from governmental and non-governmental sources.
Solicitor General
The government’s brief follows the arguments made by the Solicitor General’s brief to the Court giving the Justices its views on whether to grant certiorari. These include 1) that “Amarin’s allegations do not make out a plausible claim of active inducement to infringe”; 2) The “statements on which the Federal Circuit relied provide no basis for liability”; and 3) “[t]he Federal Circuit’s decision undermines the broader Hatch-Waxman scheme.” After providing the Court with a thorough but focused synopsis of the Act itself, the course of proceedings below, and the policy goals and questions involved, the brief provides arguments (reciting the characterization of certain of Amarin’s evidence as being “generic manufacturer’s anodyne descriptions of its product”) for the Court to reverse the Federal Circuit’s decision.
