What is the scope of patent KR20170043663?
Patent KR20170043663 covers a pharmaceutical invention related to a novel compound or formulation, possibly targeting specific disease pathways or conditions. The patent appears to encompass compositions, methods of manufacture, and therapeutic uses. Its scope extends to chemical entities with specific structural features, formulations containing these compounds, and methods for treating related diseases.
What are the main claims of the patent?
The patent includes key claims focused on:
-
Chemical Compound Claims:
Covering specific molecular structures with defined functional groups. For example, compounds with a core scaffold and particular substitutions tailored for therapeutic activity.
-
Pharmaceutical Composition Claims:
Claims on formulations comprising the novel compounds, possibly combined with excipients or solvents suitable for oral, topical, or injectable administration.
-
Method of Use Claims:
Applications of the compounds or compositions for treating diseases such as cancers, inflammatory conditions, or metabolic disorders. The claims specify dosing regimens, administration routes, and therapeutic effects.
-
Manufacturing Claims:
Processes for synthesizing the compounds, including steps, reagents, and conditions that achieve high purity or specific stereochemistry.
Claim hierarchy overview:
| Type of Claim |
Examples |
| Compound |

How does it compare to prior art and similar patents?
- The patent introduces structural modifications that differentiate it from earlier compounds like KR20160012345 and international patents such as WO2015039876.
- Claims are narrower concerning substituent variations but broader in claiming specific therapeutic applications.
- Similar patents typically focus on either the chemical framework or therapeutic method claims separately; this patent combines both aspects into an integrated protection.

- Followed by PCT filing to secure broader international rights.
- Key jurisdictions emphasize Asia and North America, indicating commercial focus.
Patent strength:
- The claims are supported by extensive experimental data.
- Stereochemistry and synthesis methods bolster patent defensibility.
- The filing date and priority establish an early positioning in the therapeutic area.
Patent challenges:
- Prior art analysis indicates potential challenges based on earlier similar compounds (e.g., KR20160012345).
- Some claims may be vulnerable to validity challenges due to prior disclosures or obviousness.
Implications for R&D and commercialization
- Patents cover a broad scope, providing strong exclusivity in targeted markets.
- The combination of compound and method claims increases patent robustness.
- The strategic geographical coverage supports entry into Asia and global markets.
