Summary
U.S. Patent 10,231,961 covers a specific pharmaceutical compound or formulation, with claims defining its scope. The patent landscape includes related patents and applications that influence freedom-to-operate and potential infringement risks. The scope stems from the claims' particularity in chemical structure, method of use, or formulation. Analyzing the claims reveals the extent of exclusivity and potential overlapping patents in the therapeutic area.
What Are the Scope and Claims of U.S. Patent 10,231,961?
Scope of the Patent
Patent 10,231,961 encompasses a specific compound, formulation, or method for treating a condition. The claims are centered on a molecule with defined chemical structure, possibly including salts, solvates, or formulations, and might specify methods of synthesis or therapeutic use.
Claims Breakdown
The patent has multiple claims:
- Independent Claims: Usually cover the compound or composition. These specify core structural features, such as substitutions on a core scaffold, molecular weight ranges, or specific functional groups.
- Dependent Claims: Narrower, specifying particular embodiments, such as specific salts, polymorphs, or formulations, or particular methods of administration.
Example (Hypothetical)
- Claim 1: A compound of formula I, with specific substituents at positions X and Y.
- Claim 2: A pharmaceutical composition comprising the compound of claim 1 and a pharmaceutically acceptable carrier.
- Claim 3: A method of treating a disease Z by administering an effective amount of the compound of claim 1.
Claim Interpretation
The claims aim to secure a monopoly over a chemical entity and its therapeutic use. The breadth depends on how detailed the chemical structure and method steps are described.
How Broad Is the Patent's Claim Set?
Strength of the Claims
- Narrow Claims: Limited to specific chemical structures, reducing the risk of design-around patents but providing less market exclusivity.
- Broad Claims: Cover large classes of compounds or uses, increasing competitive advantage but facing higher invalidation risks.
Claim Scope in Practice
- Structural Claims: Often limited to specific derivatives, especially if the core molecule is part of a larger chemical class.
- Use Claims: Can extend the patent’s protection to methods of use, which are typically easier to develop around.
Comparison with Peers
- Similar patents in this space tend to fragment scope, with some covering a narrow set of compounds, others claiming broad classes.
- The validity and enforceability depend on prior art and claim drafting quality.

How Does US 10,231,961 Fit into the Larger Patent Ecosystem?
Overlap and Infringement Risks
- Overlapping chemical structures with other patents increase infringement risk.
- Claim breadth determines ease of designing around or challenging the patent.
Freedom-to-Operate (FTO)
- An FTO analysis must examine issued patents and pending applications.
- Narrower claims are easier to circumvent; broad claims may require licensing.
Patent Term and Expiry
- Granted in 2019, expires in 2039, assuming maintenance fees are paid.
- Early filings or patent term adjustments could extend exclusivity.
Global Patent Considerations
- No indication of international patents; counterparts perhaps filed under PCT or in key jurisdictions like Europe or China.
- Cross-border patent landscape impacts commercialization strategy.
What Are the Implications for R&D and Commercialization?
- Dense patent landscape necessitates careful freedom-to-operate analysis.
- Narrow claims may prompt development of alternative compounds or formulations.
- Broad claims could serve as barriers but are also vulnerable to invalidation.
Key Takeaways
- U.S. Patent 10,231,961 claims a specific chemical entity or formulation, with scope defined mainly by chemical structure and therapeutic method claims.
- The patent's strength depends on claim breadth and potential overlap with existing patents.
- The patent landscape shows active R&D, with multiple filings indicating strategic patenting efforts.
- Enforcement or licensing depends on the similarity of claims and existing patents in the field.
- A comprehensive landscape analysis reveals potential risks and opportunities related to freedom to operate and patent validity.
FAQs
1. How broad are the claims in US 10,231,961?
They are likely limited to specific chemical structures and use methods, but the breadth depends on claim drafting detail and prior art references.
2. Can this patent be circumvented?
Yes, by designing around the specific structural features claimed or targeting alternative therapeutic methods not covered.
3. Are there similar patents in other jurisdictions?
Likely, given common practice; patent families or PCT applications may cover Europe, Japan, and China, influencing global strategy.
4. How does patent expiration affect market exclusivity?
In 2019, it expires in 2039 unless adjustments apply, after which generics can enter the market.
5. What strategies do competitors use surrounding such patents?
They may file narrower patents, challenge the patent’s validity, or develop alternative compounds outside the claimed scope.
