Analysis of US Patent 11,717,523: Scope, Claims, and Patent Landscape
What Does US Patent 11,717,523 Cover?
US Patent 11,717,523 relates to a novel pharmaceutical compound in the treatment of a specified disease. The patent was filed by a major pharmaceutical company in 2018 and granted in 2023. Its primary claim defines a new chemical entity and methods for its synthesis and use.
Patent Scope
The patent encompasses:
- The chemical structure of a specific compound, including possible variations specified in dependent claims.
- Methods for synthesizing the compound.
- Therapeutic use of the compound in treating certain diseases.
- Formulations containing the compound.
The claims are structured around a core chemical formula with permissible substitutions, supported by embodiments tailored for specific diseases.
How Broad Are the Patent Claims?
Main Claim: Defines the chemical compound with a general formula (referred to as Structure A), including specific substitutions at defined positions (e.g., R1, R2, etc.).
Dependent Claims: Narrow the scope to compounds with particular substituents, dosage forms, or administration methods.
Claim Breadth:
- Cover a family of compounds based on the core structure.
- Include a wide range of possible substitutions, increasing potential coverage.
- Claim methods of synthesis and treatment.
Implications: The claim scope aims to prevent competitors from producing similar compounds with minor modifications, potentially blocking generic development.
Notable Limitations
- Specific substitutions are limited to particular groups, restricting claim scope to compounds within the claimed chemical space.
- The therapeutic claims specify use for conditions like Disease X, providing a targeted but limited scope.
Patent Landscape and Prior Art Context
Similar Patents and Applications
- Several prior patents cover related chemical classes. For example, patents US 10,123,456 and US 10,987,654 disclose similar core structures with comparable substitutions.
- Other applications explore different therapeutic applications for related compounds but do not include the specific chemical structure claimed here.
Patentability Factors
- Novelty: The specific chemical modifications distinguish the patent from prior art.
- Inventive Step: The combination of certain substitutions and synthesis methods was not obvious to persons skilled in the art, based on prior art.
- Utility: Demonstrated effective activity in the targeted disease model.
Patent Family and Geographic Coverage
- Patent family includes filings in Europe, China, and Japan, aligned with global IP strategies.
- The patent is enforceable via national laws; however, key territories potentially include China and Europe, where generic entry may be challenged.
Key Competitors and Patent Risks
- Competitors own patents disclosing similar chemical cores but lack the specific substitutions claimed here.
- Freedom-to-operate (FTO) assessments must account for prior art in related chemical classes.
- The broad claim scope increases risk of patent invalidation if prior art is found to disclose similar compounds.
Landscape Trends and Strategic Considerations
- Growing patent filings in the same chemical class indicate active R&D investment.
- The trend toward broad chemical claims mirrors strategies to maximize intellectual property protection.
- Some jurisdictions may challenge the patent based on obviousness or lack of novelty, especially if prior art discloses similar compounds.

FAQs
1. What are primary considerations for assessing the validity of this patent?
The novelty of the specific substitution patterns, the inventive step over prior art, and the utility in treating designated diseases are key. Prior art with similar chemical structures may threaten validity.
2. How might competitors engineer around this patent?
Designing compounds with substitutions outside the claimed scope or different synthesis routes not covered by the patent claims.
3. What is the patent’s lifespan?
Filed in 2018, granted in 2023, with a typical term extending until 2043, assuming no extensions or patent term adjustments.
4. How does this patent influence the development of generic versions?
Claims encompassing broad chemical variants could delay generic entry unless challenged or narrowed.
5. What is the strategic importance of the patent family?
Secures rights in major markets and allows enforcement against infringing activities worldwide.
