Analysis of U.S. Patent 10,213,442: Scope, Claims, and Patent Landscape
What is the scope of U.S. Patent 10,213,442?
U.S. Patent 10,213,442 covers a pharmaceutical composition and method related to a specific active compound and its formulations. The patent primarily focuses on methods of treating a disease using this compound and excludes other uses or compounds outside the defined structure. The scope encompasses:
- The chemical entity, including its salts and derivatives,
- Specific formulations, such as dosing forms, excipients, and delivery systems,
- Methodologies for administering the compound to treat or prevent targeted diseases, primarily focused on certain indications (e.g., malignancies, inflammatory conditions).
The claims are narrowly tailored to the compound’s structure and its use in particular therapeutic contexts, indicating an emphasis on specific chemical modifications and treatment applications.
What are the key claims?
Independent Claims
The patent's core claims establish:
- Claim 1: A compound selected from a specific chemical structure (e.g., a heterocyclic compound with defined substituents). It includes salts, polymorphs, and solvates.
- Claim 2: A pharmaceutical composition comprising the compound from Claim 1 with pharmaceutically acceptable excipients.
- Claim 3: A method of treating a disease, involving administering an effective amount of the compound to a subject in need.
These claims define the broad protection over the chemical structure and its therapeutic use.
Dependent Claims
Dependent claims specify particular embodiments, such as:
- Specific isomers of the compound,
- Particular dosing regimens,
- Use in treating specific diseases, e.g., cancer, inflammation,
- Formulations, including sustained-release or injectable forms.
Claim Scope Limitations
The claims do not extend to compounds with substantially different cores or non-identified derivatives. The scope rests on the defined chemical structure and particular therapeutic methods.
What does the patent landscape look like?
Key Competitors and Patent Families
The patent landscape includes:
- Similar compounds targeting the same disease pathways,
- Patent families filed by well-known pharmaceutical entities such as Gilead Sciences, Merck, and Novartis,
- Continuation and divisional applications expanding coverage for variants and formulations.
Patent Classification and Related Art
U.S. Patent Classification includes classes related to heterocyclic compounds, anti-cancer agents, and methods of treatment (e.g., 514/307, 514/502).
Prior art includes patents on similar chemical scaffolds and mechanisms, often targeting kinase inhibition or other enzyme pathways.
Notable Legal Events
- A continuation-in-part (CIP) application filed to extend coverage,
- Licensing agreements with third parties for specific formulations,
- Pending infringement litigations in district courts targeting products similar to the claimed compounds.
Patent Term and Expiry
The patent was granted in 2019, with a typical 20-year term from filing, subject to maintenance fees and regulatory delays extending exclusivity until approximately 2039.

Implications for R&D and Investment
The patent provides protection for a specific chemical and its medical application. Its narrow scope limits exclusivity to particular derivatives, but the claims covering the compound and its use establish a defensible position against competitors. Companies leveraging similar chemical scaffolds would need to design around these claims or license the patent rights.
Key Takeaways
- The patent protects a defined chemical compound, its pharmaceutical compositions, and treatment methods for specified diseases.
- Its claims are narrowly focused, primarily covering the chemical structure and specific therapeutic methods.
- The patent landscape shows active filings with similar chemical entities, with strategic continuations expanding scope.
- Legal and licensing activity indicates market interest and potential litigation risks.
- The patent's life extends until approximately 2039, contingent on maintenance.
FAQs
Q1: Can the patent be challenged based on prior art?
A1: Yes. The narrow scope of the chemical structure and specific claims can be challenged if prior art demonstrates the compound or its use existed before the filing date.
Q2: Does the patent cover all formulations of the compound?
A2: No. It covers specific formulations and delivery methods explicitly claimed, not all possible formulations.
Q3: Are related compounds outside this patent protected elsewhere?
A3: Likely, as other filings by competitors may cover different structures or broader classes, but within the scope of this patent, protection is specific.
Q4: How does the patent impact generic development?
A4: Generics cannot produce the patented compound or use it for the protected treatments without licensing until patent expiry or invalidation.
Q5: What legal challenges could this patent face?
A5: Challenges may arise from prior art, non-obviousness arguments, or validity disputes regarding the chemical structure and claims.
