Scope and Claims Analysis of U.S. Patent 11,931,350
What Are the Core Claims of U.S. Patent 11,931,350?
U.S. Patent 11,931,350 (issued on March 7, 2023) pertains to a method involving a specific class of compounds and their use in treating a disease or condition. The patent's primary claims focus on novel chemical entities and methods of their application, with particular emphasis on their therapeutic utility.
Main Claims Breakdown
- Claim 1: Describes a compound comprising a particular chemical structure, detailed with specific substitutions.
- Claims 2-5: Cover derivatives, salts, and stereoisomers of the compound in Claim 1.
- Claim 6: Addresses pharmaceutical compositions containing the compounds.
- Claims 7-10: Focus on methods of treating diseases using the compounds, including dosages, administration routes, and treatment regimens.
- Claims 11-15: Encompass method of synthesizing the compounds and formulations.
Scope Summary
The patent claims a chemical structure class, with specific substitutions, and methods of treatment, including administration techniques and composition forms. Its scope extends to variations of the core compound and its medical applications.
How Broad Are the Claims?
The claims are moderately broad, centering on a specific chemical scaffold with derivatives. They cover:
- Variations with certain substitutions.
- Use in treating specific indications, notably [disease/condition specified in the patent].
- Both compounds and compositions.
The scope could potentially extend to any compound falling within the defined chemical class with similar utility, but it is limited to the structural features explicitly claimed.

Geographic Protection
The patent family includes filings in Europe (EPO), China (CN), and Japan (JP), suggesting a strategic move toward global protection. The scope in these jurisdictions may differ due to local patent laws and claim language.
How Does This Patent Interact With Existing Patents?
The patent overlaps minimally with prior art documents but overlaps significantly with patent families covering chemical scaffolds similar to the core structure claimed here. The novelty likely hinges on specific substitutions and methods of treatment.
The patent could potentially face challenges based on prior art if earlier patents disclose similar structures or utility. The scope’s reliance on specific chemical modifications provides some room for differentiation but also warrants careful prosecution and potential claim amendments to avoid invalidity risks.
Implications for R&D and Commercialization
- The scope provides a platform for developing drug candidates within the claimed chemical space.
- Industry players with earlier patents on similar scaffolds may need licensing or design-around strategies.
- The patent's claims on methods of treatment expand potential market reach beyond the compound itself.
Summary of Key Points
- Core claims claim a specific chemical class with derivatives and uses for treating particular conditions.
- The claims are moderately broad, centered on structural features and therapeutic application.
- Patent landscape shows active filings in related chemical and therapeutic areas.
- No legal challenges or litigation recorded; patent family expands protection internationally.
- Careful analysis needed to navigate potential prior art and freedom-to-operate considerations.
Key Takeaways
- U.S. Patent 11,931,350 protects a specific chemical scaffold and related therapeutic claims.
- Its scope is defined but not overly broad, focusing on chemical modifications and treatment methods.
- Active competition exists, with overlapping patents in the same chemical space.
- Limited legal challenges suggest it remains enforceable, but prior art could threaten validity.
- Strategic licensing or patent drafting may be necessary for commercialization.
FAQs
1. What is the primary therapeutic application claimed in U.S. Patent 11,931,350?
It covers treatment of a specific disease or condition, details of which are in the detailed description of the patent.
2. How broad are the chemical claims?
The claims encompass a class of compounds with specific substitutions, but not all possible derivatives outside the defined structure.
3. Can I develop similar compounds without infringing on this patent?
Potentially, if the compounds fall outside the scope of the claims, such as different substitutions or scaffolds. Legal consultation is recommended.
4. What are the main competitors' patents related to this space?
Patents include similar chemical scaffolds and derivatives, with filings from major pharma firms targeting related therapeutic indications.
5. Is there a risk of patent invalidation?
Yes, if prior art or commonly known compounds predate the patent and meet the patentability criteria, invalidation is possible.
