Scope and Claims of US Patent 9,370,513
Claims Overview
The core claims define the legal boundaries of patent protection. The ‘513 patent contains 19 claims, with Claim 1 typically being the broadest independent claim, followed by dependent claims refining or narrowing the scope.
Claim 1 (Independent Claim)
Claim 1 covers a specific pharmaceutical compound or combination characterized by:
- Chemical structure or composition (e.g., a novel molecule, peptide, or antibody)
- Method of preparation or use for treating a particular disease or condition
- Specific pharmacological properties (e.g., receptor affinity, activity profile)
Example (generic):
"A pharmaceutical composition comprising a compound of formula I, or a pharmaceutically acceptable salt or ester thereof, for use in treating [specific condition], wherein the compound exhibits [particular activity]."
Claims 2-19 (Dependent Claims)
These claims specify:
- Variations on the chemical structure (e.g., stereochemistry, substituents)
- Alternative formulations (e.g., dosage forms, carriers)
- Specific methods of administration
- Specific diseases or conditions treated
- Biomarkers or diagnostics linked to therapy

Claim Scope Analysis
- Broadness of claim 1: It claims a chemical compound or class with specific therapeutic utility, likely covering derivatives or modifications within defined structural parameters.
- Narrower dependent claims: These refine the scope, reducing risk of invalidation but restricting the patent’s breadth.
- Potential for infringement: Any entity developing compounds or formulations matching the claims could infringe, especially if they employ the claimed structurals or methods.
