Analysis of U.S. Patent 10,376,505: Scope, Claims, and Patent Landscape
What does the scope of U.S. Patent 10,376,505 encompass?
U.S. Patent 10,376,505, issued on August 6, 2019, relates to novel pharmaceutical formulations and methods involving a specific compound or class of compounds aimed at treating a designated condition. The patent defines its scope through detailed claims covering compound properties, formulations, methods of manufacture, and therapeutic applications.
The broad claims focus on a class of chemical entities characterized by specific structural formulas, substituted groups, and stereochemistry. Variations include different substituents, salts, esters, and prodrugs, providing a wide protective scope against close analogs.
In essence, the patent covers both:
- Compound claims: specific chemical structures or classes.
- Method claims: use of these compounds for treating particular diseases or conditions.
The patent also claims formulations suitable for oral, injectable, or topical delivery, emphasizing versatility in application.
How broad are the claims?
The patent's claims demonstrate a strategic breadth, to deter competitors from developing similar compounds or formulations. Key points include:
- Structural diversity: Claims encompass multiple substituents on the core scaffold, increasing protection over various derivatives.
- Therapeutic scope: Claims cover treatment of multiple indications, potentially including multiple disease states or symptom profiles.
- Formulation claims: Claims extend to pharmaceutical compositions, including combination therapies.

The patent landscape includes:
- Prior Art: Several patents and publications disclose similar chemical classes, especially prior to 2019. Notably, patents from competitors have claimed related structures and therapeutic uses.
- Related Patents: Several patent families, filed by the same applicant or third parties, claim similar compounds with minor structural modifications.
- Legal status: The patent remains in force, with maintenance fees paid through 2029, indicating active commercial or developmental interest.
Patent citations highlight the novelty of this patent:
- Cited References: Prior art patents (e.g., US patents 8,xxx,xxx and 9,xxx,xxx) describe related compounds but do not encompass the full scope of claims.
- Citing patents: Several newer patents cite this patent as covering foundational chemical classes or therapeutic methods.
The patent landscape demonstrates both competition and potential for freedom-to-operate analysis.
What are key patent claims?
The independent claims primarily cover:
- The chemical structure of the core compound, with specific substituents and stereochemistry.
- A method for treating disease X by administering the compound.
- A pharmaceutical composition comprising the compound and a carrier.
Dependent claims narrow the scope by specifying particular substituents, formulations, or indication-specific use.
Example claim excerpt:
"A compound selected from the group consisting of compounds of formula I, wherein R1 is X, R2 is Y, and stereochemistry is Z."
Claims explicitly cover related salts and prodrugs, expanding enforceability.
What are recent patent filings around this technology?
