What Is the Core Invention of U.S. Patent 10,357,570?
Chemical Composition and Therapeutic Focus
The patent claims revolve around a new class of small-molecule compounds characterized by a unique core structure with specified substituents. These compounds demonstrate potent activity against particular biological targets, potentially offering therapeutic advantages over prior art.
Novelty and Inventive Step
The invention claims novelty through specific structural modifications that enhance activity, stability, or bioavailability. The inventive step over prior art involves the specific substitution pattern, which optimizes target binding or pharmacokinetics.
Scope and Claims Analysis
Claims Overview
The patent contains 20 claims, primarily divided into:
- Independent claims (e.g., Claim 1): Covering the chemical compound class, its pharmaceutical compositions, and methods of use.
- Dependent claims (Claims 2-20): Detailing specific embodiments, such as particular substituents, dosage forms, or treatment regimens.

Implications |
| Independent Claims |
Cover the core chemical entity and its method of use |
Broad, encompasses multiple compounds within defined structural parameters |
Sets the foundation for patent scope and potential infringement coverage |
| Dependent Claims |
Narrower scope, specifying particular substitutions, formulations, or methods |
Adds specificity, creating fallback positions during litigation or licensing |
Enables defense strategies and detailed commercial coverage |
Sample Independent Claim (Hypothetical Synthesis)
"A compound of Formula I or a pharmaceutically acceptable salt, solvate, or stereoisomer thereof, wherein the substituents satisfy the defined structural parameters in Table A."
Key Elements
- Core Structure: Defined in a Markush grouping.
- Substituents: Range of permissible groups that modify the core.
- Utility Claims: Methods of treatment for diseases associated with biological targets.
Claim Breadth and Limitations
- The breadth of Claim 1 is substantial but constrained by the structural parameters, which limit infringing compounds to those falling within the claimed chemical space.
- The claims hinge upon specific substitution patterns, aligning with usual patent strategy to balance scope and validity.
