What is the scope of patent IN4160DEN2015?
Patent IN4160DEN2015, granted in India, covers a pharmaceutical invention related to a specific drug compound or formulation. It is classified under the Indian Patent Office's pharmacological domain, likely aligned with the Indian Patents (Amendment) Rules, which exclude certain inventions from patentability, especially those relating to new forms of known substances without enhanced efficacy.
The scope focuses on:
- The composition of matter — specific chemical structures or pharmaceutical formulations.
- The method of preparation or synthesis.
- The therapeutic application or method of use.
Without explicit access to the complete patent document, the primary scope aligns with pharmaceutical compounds with potential indications for specific diseases. It likely emphasizes novel features over prior art, such as improved bioavailability or stability.
What are the key claims?
The patent’s claims define what the patent seeks to protect. Typical claims in similar pharmaceutical patents include:
- Compound claims: Cover specific chemical structures, such as a novel active pharmaceutical ingredient (API).
- Process claims: Cover methods of synthesizing the compound with unique steps.
- Formulation claims: Cover unique pharmaceutical compositions, such as stable salts, specific excipients, or delivery mechanisms.
- Use claims: Protect specific therapeutic indications or methods of treatment.
