Main Claims Breakdown
| Claim Type |
Number |
Description |
| Composition of matter |
1-20 |
Defines the chemical structure, including substituent variations, stereochemistry, and specific molecular frameworks. This forms the core of the patent's scope. |
| Method of synthesis |
21-35 |
Details innovative synthesis processes enabling efficient or selective production of the claimed compounds. |
| Therapeutic use |
36-45 |
Claims the use of the compounds in treating specific medical conditions, often based on observed or hypothesized pharmacological activity. |
| Combination therapies |
46-55 |
Claims where the compounds are used in combination with other therapeutic agents, enhancing efficacy or reducing side effects. |
Notable Claims Analysis
- Compound claims: Cover a primary core structure with a range of possible substituents. For example, claim 1 may define a novel heterocyclic molecule with specific functional groups attached.
- Use claims: Focused on the treatment of [disease], with claims extending to prophylactic and therapeutic applications.
- Process claims: Emphasize methods that improve synthesis efficiency or purity, potentially reducing production costs and increasing patent enforceability.
Chemical Structural Scope
The patent defines a chemical genus with the following properties:
- Core scaffold: [e.g., quinazoline, pyrimidine, etc.]
- Substituents: [e.g., halogens, alkyl groups, cycloalkyls]
- Stereochemistry: Specific chiral centers, R/S configurations
Example Structural Claim
Claim 1: A compound of the formula [Chemical formula], wherein R¹ is selected from hydrogen, halogen, or alkyl, and R² is a heterocyclic group, with the proviso that the compound is not [specific prior art compound].
This structure emphasizes the patent's aim to carve out a novel chemical space distinct from known molecules, with sufficient differentiation to provide enforceable scope.
