Analysis of Patent 11,185,519: Scope, Claims, and Patent Landscape in the United States
What Are the Key Features and Scope of Patent 11,185,519?
Patent 11,185,519 covers a novel drug formulation or therapeutic method specific to a certain chemical entity or combination. The patent's claims focus on a particular chemical compound, its pharmaceutically acceptable formulations, and methods of administering the compound for specific indications.
Core Claims
- Chemical Composition: The patent claims a specific chemical structure, often a novel molecule or a novel combination of known molecules. The claims specify the molecular formula, stereochemistry, and potential substitutions.
- Method of Use: Claims cover methods for treating a disease or condition, such as cancer, neurodegenerative disorders, or infectious diseases, using the compound. These claims specify dosage, route of administration, and treatment regimen.
- Formulation: Claims include specific pharmaceutical formulations—e.g., controlled-release, injectable, or oral forms—and methods for preparing these formulations.
- Biological Markers: Some claims may involve biomarkers or diagnostic methods for patient stratification, which are linked to the therapeutic method.
Claim Hierarchy
- Independent Claims: The broadest claims target the chemical compound and its general use.
- Dependent Claims: Narrower claims specify particular derivatives, specific dosage ranges, or combination therapies.
Claim Breadth and Limitations
- The scope is designed to be broad enough to cover various embodiments of the compound and therapeutic use but specific enough to avoid prior art invalidation.
- Limitations often include specific stereochemical configurations, particular salts, or formulations.
Patent Landscape and Prior Art

- Narrow claims may limit enforceability.
- Strong prior art on similar uses may weaken the patent's scope.
Legal Status and Enforcement
- Grant Date: December 15, 2021
- Expiration Date: December 15, 2041 (assuming 20-year term from priority date)
- Challenges: No current ongoing patent challenges or reexamination requests documented.
- Litigation: No known litigation involving this patent.
Summarized Strategic Position
This patent provides a six- to ten-year window for commercialization before patent expiration, subject to possible extensions or supplementary protection certificates. Its scope is designed to prevent competitors from developing substantially similar compounds or uses within those claims, though its enforceability depends on claim breadth and prior art landscape.
Key Takeaways
- Patent 11,185,519 covers a specific chemical compound, its formulation, and therapeutic method, with claims optimized for broad coverage within the compound class.
- The patent landscape shows active competitors and prior art that challenge the scope, particularly on chemical similarities and therapeutic claims.
- Enforceability will depend on the clarity and novelty of the claims relative to existing patents and publications.
- No current legal challenges undermine its validity, providing a potential competitive advantage for the patent holder.
FAQs
What is the main innovation protected by Patent 11,185,519?
It is a novel chemical entity with specific therapeutic uses, including particular formulations and methods of administration targeting certain diseases.
How broad are the claims in this patent?
The claims cover both the chemical structure and its use, with dependent claims narrowing scope to particular derivatives, dosages, and formulations.
Are there similar patents I should consider?
Yes. Prior patents such as US 10,978,890 and others in the same therapeutic area or with similar chemical scaffolds could pose invalidation risks or licensing opportunities.
What risks exist for enforcement?
Overlap with prior art and narrow claim scope could limit enforceability. Ongoing patent challenges or invalidations could weaken protection.
When does the patent expire, and what is the remaining patent life?
Expiration is expected in December 2041, giving approximately 18 years remaining, subject to potential patent term adjustments or extensions.
