By Kevin E. Noonan --
On Friday, August 26th, Moderna Tx, Inc. and Moderna US, Inc. filed a complaint for patent infringement in Federal district court for the District of Massachusetts against Pfizer, Inc., BioNTech SE, BioNTech Manufacturing GmbH, and BioNTech US, Inc. (A parallel suit was filed in Germany asserting Moderna's corresponding German patents.) There are several interesting aspects to this complaint, and perhaps of even greater interest has been the reaction to the filing in light of Moderna's earlier "pledge" to refrain from asserting any of its patents "during the pandemic."
The complaint asserts three patents, identified herein in the context of the claims set forth in the complaint itself:
U.S. Patent No. 10,898,574
Claim 2. A pharmaceutical composition comprising:
a plurality of lipid nanoparticles comprising a cationic lipid, a sterol, and a PEG-lipid,
wherein the lipid nanoparticles comprise an mRNA encoding a polypeptide,
wherein the mRNA comprises one or more uridines, one or more cytidines, one or more adenosines, and one or more guanosines and wherein substantially all uridines are modified uridines.
Claim 9. The pharmaceutical composition of claim 2, wherein the modified uridine is 1-methyl-pseudouridine.
U.S. Patent No. 10,702,600
Claim 1. A composition, comprising:
a messenger ribonucleic acid (mRNA) comprising an open reading frame encoding a betacoronavirus (BetaCoV) S protein or S protein subunit formulated in a lipid nanoparticle.
U.S. Patent No. 10,933,127
Claim 1. A method comprising administering to a subject
a messenger ribonucleic acid (mRNA) comprising an open reading frame encoding a betacoronavirus (BetaCoV) S protein or S protein subunit formulated in a lipid nanoparticle
in an effective amount to induce in the subject an immune response to the BetaCoV S protein or S protein subunit
wherein the lipid nanoparticle comprises 20-60 mol% ionizable cationic lipid, 5-25 mol% neutral lipid, 25-55 mol% cholesterol, and 0.5-15 mol% PEG-modified lipid.
Of these three asserted patents, the '574 patent has the broadest claims, not being limited to a particular virus or antigenic protein thereof, while the '600 and '127 patents expressly recite mRNAs encoding a b-coronavirus Spike protein; these claims would encompass vaccines to SARS-CoV-1 (the original SARS pandemic vaccine) as well as MERS and SARS-CoV-2 (COVID19). These claims in particular form a basis for Moderna's allegations of infringement by the Pfizer/BioNTech Comirnaty® vaccine, as recited in several paragraphs in the complaint. In particular, Moderna alleges that the Comirnaty® vaccine was a direct copy of their vaccine (a path taken over three other competing candidate vaccines), citing public statements by Pfizer CEO Albert Bourla on June 9, 2020, at Goldman Sachs Virtual 41st Annual Global Healthcare Conference (¶20 of the complaint).
Perhaps in recognition of the post-pandemic patent zeitgeist, the complaint has two remarkable features. The first is a long expostulatory section explaining the long antecedents of the technology Moderna was able to apply towards making its Spike mRNA SARS-CoV-2 vaccine (and the skepticism those efforts elicited pre-pandemic). This portion of the complaint includes a history of Moderna's development of the underlying mRNA technology as well as its efforts to develop its vaccine (unnoted is that Moderna abjured participation in "Operation Warp Speed" with its attendant Federal government financial support) during the pandemic (and makes the point that their technology is not limited to vaccines against COVID infections). The complaint also makes the case that the company's IP was both the technical foundation for its successful and rapid development of the COVID vaccine and provided protection against the significant financial and investment risk occasioned by Moderna's development of its vaccine.
The second remarkable feature of the complaint, and Moderna's strategy in bringing suit, is in the Prayer for Relief (and certain sections explaining the limitations of the remedy Moderna asks the Court to grant). In addition to a judgment that Pfizer and BioNTech infringe by sales of its Comirnaty® vaccine (and that such infringement was willful), Moderna seeks money damages that expressly exclude damages it would be entitled to from "sales to the U.S. government that are subject to 28 U.S.C. § 1498 or to the 92 low- and middle-income countries in the Gavi COVAX Advance Market Commitment (AMC)." And in the litany of other remedies routinely requested in patent infringement cases (a finding that this is an exceptional case, with an award of attorneys' fees, costs, and expenses under 35 U.S.C. § 285, and treble damages for willful infringement under 35 U.S.C. § 284), expressly excluded is an injunction from "such other relief the Court may deem just and proper." Deigning to forego compensation for sales to the government under 28 U.S.C. § 1498 is likely done in an effort to avoid any attempt by Pfizer or BioNTech to have the case adjudicated under the statute in the Court of Federal Claims; disclaiming any interest in sales outside the U.S. to countries falling within the scope of the COMAX AMC avoids (or at least tries to) allegations that Moderna is putting its profits and patent rights over the health and lives of the citizens of those countries.
The complaint also addresses Moderna's promises regarding assertion of its IP, specifically quoting its October 8, 2020 press release stating that "while the pandemic continues, Moderna will not enforce our COVID-19 related patents against those making vaccines intended to combat the pandemic" (italics in original) (¶22). The complaint also provides Moderna's rationale and justification for filing this complaint at this time:
By early 2022, however, the collective fight against COVID-19 had entered a new endemic phase and vaccine supply was no longer a barrier to access in many parts of the world, including the United States. In view of these developments, Moderna announced on March 7, 2022, that it expected companies such as Pfizer and BioNTech to respect Moderna's intellectual property and would consider a commercially-reasonable license should they request one. This announcement was widely publicized, including through coverage in The Wall Street Journal. Critically, however, and to further its belief that intellectual property should never be a barrier to access, as part of this announcement, Moderna committed to never enforce its patents for any COVID-19 vaccine used in the 92 low- and middle-income countries in the Gavi COVAX Advance Market Commitment ("AMC"). This includes any product manufactured outside the AMC countries, such as the World Health Organization's project in South Africa, with respect to COVID-19 vaccines destined for and used in the AMC-92 countries. Although they have continued to use Moderna's intellectual property, Pfizer and BioNTech have not reached out to Moderna to discuss a license. (¶23)
The complaint has nonetheless raised the issue of the status of Moderna's promise in the context of patent pledges in other industries, notably for standard-essential patents (SEP) and FRAND ("fair, reasonable, and non-discriminatory") agreements. Academics (in particular, Jacob Sherkow from the University of Illinois Law School and Jorge Contreras, S.J. Quinney College of Law, University of Utah Law School) have raised the specter of successful suit by Moderna in the face of its earlier promise as creating a challenge threatening the substantial edifice of patent pledges used in these other contexts. Some distinctions immediately come to mind, however. One is that the patent pledges in the SEP/FRAND context are associated with consideration for the pledging party, that consideration consisting of, inter alia, compliance by companies licensing SEPs owned by the pledging patentee that provide stability and consistency in licensing regimes and create impediments against non-compliant companies. Moderna received no such consideration for its pledge (and the effects of any "good will" it might have hoped to gain was ephemeral; after all, all the pledges in the world did not deter the WTO from adopting a patent waiver agreement at the behest of India, South Africa, and other countries who could expect to benefit and did benefit from agreements like the one in Moderna's complaint exempting sales to the COVAX AMC countries from any damages claims sought by Moderna). Another distinction is that a fair reading of Moderna's promise-by-press-release was its essentially contingent nature; forgoing (or postponing exercise of) its patent rights was always limited to during the pandemic (although it is a fair question to ask who decides when the pandemic is over). Finally it is not unfair to say that the SEP/FRAND situation is vastly different from patenting vaccines against a pandemic virus; there is, after all, no analogous risk to global health and welfare arising from patent pledges relating to such patents.
On the other hand, if a court does hold Moderna's patent promise to be enforceable (under the doctrine of promissory estoppel, for example), it most likely will be the last time any biotechnology or pharmaceutical company makes such a promise.
There is one other consideration here that may explain Moderna's willingness to file suit at this time that abjures the lion's share of any damages it could reasonably have expected to receive. Moderna has achieved something of a Holy Grail of patenting: true platform patents that can be and will be used for the next vaccine, and the one after that, etc. Bringing a successful suit might result in a healthy damages award but these may pale compared with what could happen during the ~10 -15 years of patent life remaining. Of course, any suit brings risks and it is not unlikely that Pfizer/BioNTech will petition for inter partes review; indeed, at least one patent owned by the University of Pennsylvania, U.S. Patent No. 8,691,966 (naming BioNTech principal Katalin Kariko as an inventor), discloses and claims mRNA modifications comprising 1-methylpseudouridine (albeit outside the SARS context); this patent has an earliest priority date about 4 years prior to Moderna's patents asserted in the litigation.
All these considerations make for a compelling story that will almost certainly be the subject of future posts.
