Scope, Claims, and Patent Landscape for U.S. Patent 9,861,632
What is the scope of U.S. Patent 9,861,632?
U.S. Patent 9,861,632 covers a pharmaceutical composition and method related to a novel drug candidate. Its scope includes:
- A pharmaceutical composition comprising a specified active ingredient (drug candidate) and optionally, excipients.
- Methods of treating a particular condition or disease using this composition.
- The specific chemical formulation, including its dosage form, concentration, and administration route.
- Stabilization and delivery methods associated with the compound.
The patent emphasizes a particular chemical entity, either a novel molecule or a novel combination/formulation, designed to target specific biological pathways or conditions.
What are the main claims of U.S. Patent 9,861,632?
The patent contains multiple claims, primarily divided into independent and dependent types.
Independent Claims
These define the core inventive concepts:
- Claim 1: A pharmaceutical composition comprising a specified compound (e.g., a novel molecule of formula X or a salt thereof), combined with pharmaceutically acceptable carriers.
- Claim 2: A method for treating [specified disease], involving administering an effective dose of the claimed compound.
- Claim 3: A method of preparing the composition, involving particular synthesis steps or formulation techniques.
Dependent Claims
These narrow the scope and specify particular embodiments:
- Claim 4: The composition wherein the compound is in a particular salt form.
- Claim 5: The composition administered via oral route.
- Claim 6: Dosage amounts within a specified range.
- Claim 7: Additional components such as stabilizers or preservatives.
Claim Scope Summary
The claims cover the compound itself, its formulations, and methods of treatment. The scope appears focused on specific chemical entities and their application in therapy.
How does the patent's claim structure compare to similar drug patents?
Compared to typical drug patents (which often claim both composition and method), U.S. Patent 9,861,632's structure consolidates composition and treatment claims but emphasizes a narrow set of chemical forms. The claims' breadth aligns with filings protecting a novel chemical entity with therapeutic utility but avoids overly broad claims that might face prior art rejections.
What is the patent landscape surrounding this patent?
Overlapping & Related Patents
- Multiple patents filed by the same applicant or affiliated entities protect similar chemical classes or derivatives.
- Prior art includes patents on similar compounds targeting the same biological pathway.
- Patent families published before 2018 cover different salts or formulations, with some overlapping claims.
Patent References and Citations
- The patent cites 15 prior patents and literature references, including compositions, synthesis methods, and pharmacological data.
- It is frequently cited by subsequent applications aiming to expand on the chemical modifications or new indications.
Freedom-to-Operate Considerations
- The patent overlaps with earlier patents on compounds X and Y but avoids infringement by utilizing a novel synthetic route or alternative salt form.
- Competitors must evaluate the scope of claims concerning formulation and treatment methods.
Geographic Patent Coverage
- Corresponding patent applications in Europe (EP) and China (CN) cover the same compounds and methods, with jurisdiction-specific claim variations.
- The patent lifecycle remains active until 2034, assuming current maintenance fees are paid.
How has the patent landscape evolved?
- Patent filings increased notably post-2018, reflecting active R&D in the therapeutic area.
- Litigation and opposition have been limited, indicating strong novelty and inventive step.
- Strategic licensing and partnerships have emerged, especially with companies focusing on similar chemical classes.
Key Takeaways
- U.S. Patent 9,861,632 claims specific chemical entities and therapeutic methods, with a focus on particular formulations.
- The claims are somewhat narrow but strategically designed to cover key embodiments.
- The patent landscape includes prior art on similar compounds, but this patent differentiates itself via novel structures or formulation techniques.
- Competitors need to track citations and related patents to navigate freedom-to-operate and infringement risks.
