- Method Claims: Cover therapeutic methods involving administering the claimed compounds to treat specific diseases, such as cancers (e.g., lung, breast, or colorectal) or neurological conditions.
- Synthesis Claims: Define a novel synthetic route to generate the compounds with improved efficiency or selectivity.
- Use Claims: Methods of using the compounds in combination with other agents, or for particular indications.
2. Dependent Claims:
Dependent claims specify particular substituents, salts, polymorphs, or formulations, providing narrower protection and enabling strategic licensing or enforcement.
Claim Scope Specifics:
- Chemical Diversity: The claims include variants where the heterocyclic core can be substituted with different groups, expanding the patent's coverage over a broad chemical space.
- Therapeutic Focus: Claims specify particular disease states such as advanced solid tumors, gliomas, or neurodegeneration, emphasizing application breadth.
- Delivery Techniques: Claims on targeted delivery systems, including nanoparticle formulations, are present to enhance specificity and patent protection.
