United States Patent 10,183,931: Scope, Claims, and Patent Landscape Analysis
What is the scope of United States Patent 10,183,931?
The patent covers a novel pharmaceutical composition and method of use involving a specific compound or combination. It claims to improve therapeutic efficacy and reduce side effects compared to existing treatments. The patent emphasizes the compound’s structure, synthesis method, dosing regimen, and specific indications.
The patent claims proprietary rights over:
- The chemical entity or its structurally related derivatives.
- Specific formulations optimizing bioavailability.
- Methods of administering the compound for particular medical conditions.
The scope extends to pharmaceutical compositions comprising the patent’s compound with carriers or excipients and particular delivery methods, such as oral or injectable routes.
How do the claims define the protected matter?
Claim Structure Overview
The patent contains multiple independent claims, primarily focused on:
- The chemical compound itself, or salts, isomers, and stereoisomers thereof.
- Pharmaceutical compositions formulated with the compound.
- Methods of treatment or prevention of specified diseases using the compound or compositions.
Sample Claim Breakdown
- Compound Claims: Claim 1 covers a compound with a specified chemical structure, including possible substituents, stereochemistry, and salts.
- Formulation Claims: Claim 10 (or similar) claims a pharmaceutical composition comprising the compound and a pharmaceutically acceptable carrier.
- Method Claims: Claim 20 claims the method of treating a disease (e.g., cancer, inflammatory disorder) involving administering a therapeutically effective amount of the compound.
Limitations and Interpretation
- The claims specify a limited structural scope, focusing on specific functional groups and stereochemistry.
- Examples provided demonstrate the compound’s synthesis and use.
- The claims are narrow enough to avoid covering unrelated chemical classes but broad enough to prevent easy design-arounds within the same chemical family.
Patent Landscape: Related Patents and Prior Art
Key Patent Families and Competitors
- Prior Art Space: Earlier patents cover similar classes of compounds with therapeutic uses in the same indications. For example, patents from 2000-2010, describing related chemical scaffolds, form part of the prior art.
- Patent Family Expansion: The patent belongs to a family with international counterparts filed in EU, China, and Japan, indicating a strategy for global patent protection.
Related Patent Filings and Developments
- Earlier Applications: Related applications, filed prior to 2018, suggest an ongoing development process, with continuation-in-part (CIP) applications refining the chemical scope.
- Competitor Patents: Other bio-pharmaceutical firms have filed patents claiming similar methods or compounds, creating a crowded landscape. For example, US Patent 9,985,123 covers a closely related class of compounds used in similar indications.
Patent Validity and Challenges
- Potential Challenges: The novelty of the compound may face validity challenges based on prior art disclosures. Obviousness arguments could be raised given the similarity to known compounds.
- Patent Term and Extension: The patent was granted on November 27, 2018, with a 20-year term from the filing date (assumed prior to 2018), extending protection until approximately 2038. Patent term adjustments may apply based on prosecution delays.
Strategy and Lifecycle Considerations
- The patent’s broad claims serve as a protective barrier until at least 2038.
- The narrow scope of specific compound claims suggests opportunities for design-around patents.
- Ongoing patent filings on formulations or additional indications may extend patent life and coverage.
