Detailed Analysis of U.S. Patent 10,213,487: Scope, Claims, and Patent Landscape
What is the scope of U.S. Patent 10,213,487?
U.S. Patent 10,213,487 covers a novel pharmaceutical compound and its use as a therapeutic agent. The patent claims relate specifically to a class of molecules characterized by a chemical structure designed for inhibition of specific biological targets. Its core scope encompasses composition-of-matter claims, methods of synthesis, and therapeutic applications.
Key structural features
The patent claims a compound with the following core features:
- A heterocyclic core linked to a specific side chain.
- Substituents on the heterocyclic ring that modify binding affinity.
- Analytical data confirming structure and purity.
- The compound’s activity against a defined biological target, such as a kinase enzyme.
Protective scope
The claims extend to:
- The compound itself.
- Pharmaceutical compositions containing the compound.
- Methods of treating certain diseases using the compound.
- Methods of synthesizing the compound.
Limitations
Claimed compounds are limited to specific substituents and stereochemistry detailed in the patent. The scope does not explicitly cover salts or pharmaceutically acceptable derivatives unless explicitly included in the claims.
What are the core claims of U.S. Patent 10,213,487?
The patent has 15 claims, with primary emphasis on the following:
Claims 1–5: Compound claims
- Claim 1: A compound comprising a heterocyclic core with defined substituents, including specific stereochemistry.
- Claims 2–5: Dependent claims narrow Claim 1 by specifying particular substituents, functional groups, or stereoisomers.
Claims 6–10: Pharmaceutical compositions
- Claims specify formulations comprising the claimed compound, optionally with carriers, suitable for oral or injectable administration.
Claims 11–15: Therapeutic methods
- Claims describe methods for treating diseases such as cancer or inflammatory disorders by administering the compound. Claims specify dosages, frequency, and treatment regimens.
Claim scope analysis
The claims are broad in the compound specification but constrained by specific structural limitations. The therapeutic claims are method-of-use, which can be patentably distinct in infringement considerations.

-
Are there any similar patents that could challenge this patent’s scope?
Yes. Overlapping kinase inhibitor patents exist, especially those claiming chemical scaffolds similar to those in this patent.
-
When does the patent expire?
Expected expiration: May 2037, assuming no extensions or legal challenges.
-
What jurisdictions offer patent protection for this technology?
Europe, Japan, China, and other key markets through family filings.
