2. Scope of the Claims in U.S. Patent 11,717,504
2.1. Core Claims
The core claims define the inventive chemical entity or formulation, which may include:
- Chemical Structure Claims: Covering a specific compound, or a class of compounds, with defined substituents and stereochemistry.
- Pharmacological Effect Claims: Claims tied to therapeutic efficacy for specific indications, such as reducing inflammation, managing metabolic disorders, or targeting specific receptors.
- Formulation Claims: Covering pharmaceutically acceptable compositions, dosage forms, and delivery systems (e.g., tablets, injectables, transdermal patches).
- Method Claims: Specific methods of producing the compound, including synthesis steps, purification techniques, or modifications.
2.2. Claim Hierarchy and Types
| Claim Type |
Description |
Example |
| Independent |
Broadest claim covering the chemical entity or process |
“A compound of Formula I…” |
| Dependent |
Narrower claims adding further limitations |
“The compound of claim 1, wherein R1 is…” |
| Use Claims |
Specific therapeutic or industrial uses |
“Use of the compound for treating disease X…” |
| Formulation Claims |
Specific pharmaceutical compositions |
“A pharmaceutical composition comprising the compound and excipient Y…” |
2.3. Claim Language and Limitations
The language emphasizes chemical stereochemistry, purity thresholds, specific functional groups, and manufacturing conditions, aiming to prevent easy arounds.
3. Patent Landscape Analysis
3.1. Prior Art and Background
Prior art primarily includes:
- Related chemical classes: Similar compounds with known therapeutic activity.
- Existing patents in the same therapeutic area: Often filed in major jurisdictions (e.g., EP, WO, CN, JP) that cover analogous compounds or uses.
- Literature: Scientific publications prior to 2021 describing compounds or methods related to the invention.
