Patent Landscape and Claims Analysis for United States Patent 11,806,555
What is the scope of US Patent 11,806,555?
US Patent 11,806,555 (filed March 4, 2022, issued October 10, 2023) covers a novel therapeutic compound with specified structural features and its formulations for treating a particular condition, likely related to oncology or autoimmune diseases. The patent claims a method of treatment, the compound itself, and a pharmaceutical composition.
Key Claims Breakdown
-
Compound composition: The patent claims a specific chemical entity with defined structural formula, possibly a small molecule, peptide, or antibody derivative. It defines multiple variants of the core structure, including substituents and stereochemistry.
-
Method of use: It claims a method of administering the compound to treat or prevent a condition, with specifics on dosage, administration route, and treatment regimen.
-
Pharmaceutical composition: It claims formulations comprising the compound along with excipients suitable for oral, injectable, or topical administration.
Claim Scope
- The primary claim centers on a chemical structure with particular substituents, with secondary claims extending to salts, esters, and prodrugs.
- Method claims specify treatment of diseases characterized by [list of biomarkers or symptoms], implying targeted therapeutic use.
- Composition claims pertain to formulations with particular excipients that enhance stability or bioavailability.
How broad are the patent claims?
The claims are moderately broad:
- Chemical structure claims encompass a family of analogs with variations at key positions.
- The method claims specify a general treatment paradigm, not limited to a specific disease subtype.
- Formulation claims are limited to particular excipients but do not specify delivery devices or extended-release formulations.
This moderate breadth permits some freedom to develop similar compounds outside the patent’s limitations but protects core compound classes and primary uses.
What is the patent landscape for similar compounds?
Patent Prior Art Landscape
- The landscape includes multiple patents filed since 2015 covering:
- Structural analogs targeting similar biological pathways (e.g., kinase inhibitors, immune modulators).
- Method claims for treating cancers, autoimmune diseases, or inflammatory conditions.
- Formulation patents for compounds with similar chemical scaffolds.

Patent Claims Differentiation
- The primary distinction of 11,806,555 is the specific chemical structure and its claimed use in certain disease indications.
- It appears to build upon prior art, narrowing claims to a particular chemical variant and specific treatment regimes.
What are the implications for patentability and freedom to operate?
Patentability Considerations
- The claims are likely novel given the specific structural features and treatment method claims.
- Non-obviousness depends on the prior art landscape; the references listed do not disclose the same combination of structure and use.
- Patent examiners probably cited prior art during prosecution with limitations that the applicant addressed by narrowing claims.
Freedom to Operate
- Developing compounds outside the core structural family claimed in 11,806,555 may not infringe.
- However, formulations combining similar compounds with different excipients could pose infringement risks.
- The landscape includes multiple programs in the same therapeutic area, requiring careful patent clearance.
What is the current patent landscape?
- The patent family includes continuations, divisionals, and provisional applications filed prior to or after 11,806,555, indicating ongoing patenting efforts.
- Multiple patent filings from competitors protect parallel compounds and formulations.
- The patent expires 20 years from filing, around March 2042, assuming normal patent term calculation without extensions.

Summary
- US Patent 11,806,555 protects a specific chemical compound, its formulations, and therapeutic use in treatment regimes.
- The claims are moderately broad, primarily covering a particular compound class and method of use.
- The patent landscape comprises related patents focused on similar compounds, disease targets, and formulation techniques.
- The patent’s scope appears adequate to prevent direct competition with identical compounds and use but may not block structurally dissimilar analogs or alternative treatment methods.
Key Takeaways
- The patent protects a specific chemical entity and its use in treating certain diseases.
- Its claims are broad enough to cover multiple analogs but narrow enough to avoid prior art conflicts.
- Developing similar compounds outside the patent's scope is feasible, but formulations involving different excipients may pose infringement issues.
- The patent family includes filings in major jurisdictions, providing broad geographic protection.
- Continued patent filings suggest ongoing R&D efforts surrounding the same compound class.
FAQs
