U.S. Patent 11,000,653, granted to ModernaTX, Inc. on March 9, 2021, covers specific compositions and methods related to mRNA technology. The patent broadly focuses on lipid nanoparticle delivery systems for encapsulating messenger RNA (mRNA) sequences, particularly in the context of vaccines.
The patent claims cover the following main aspects:
- Lipid nanoparticle compositions optimized for mRNA delivery with specific lipid constituents, including ionizable lipids, phospholipids, cholesterol, and PEG-lipids.
- Methods of producing these lipid nanoparticles.
- The encapsulation of mRNA sequences encoding target antigens.
- Use of these compositions for eliciting an immune response, especially in vaccine applications.
The scope emphasizes lipid formulations with specific structural features—such as ionizable lipids with particular headgroups and hydrocarbon chains—optimized for stability, delivery efficiency, and low toxicity.
How Do the Claims Define the Patent’s Coverage?
The patent contains 28 claims, with the broadest encompassing the composition of lipid nanoparticles with defined lipid components:
- Claim 1: A lipid nanoparticle comprising an ionizable lipid, phospholipid, cholesterol, and a PEG-lipid, where the ionizable lipid is characterized by specific structural features (e.g., a desired pKa range, hydrocarbon chain length).
- Claims 2–5: Variations of Claim 1, detailing specific ratios, compositions, and manufacturing methods.
- Claims 6–15: Methods of producing the nanoparticles, including steps like mixing lipid components under certain conditions.
- Claims 16–28: Methods of delivering mRNA using the claimed lipid nanoparticles and methods of inducing an immune response.
The claims are focused on both the composition and methods, covering broad formulations and specific delivery techniques. The specific structural features of the lipid components are central to the patent's coverage.
