Patent Overview and Context
Patent Publication Number: WO2013009674
Publication Date: January 17, 2013
Applicant: (Specific applicant details are based on the original application data)
Priority Date: (Determined by earliest filing within the priority chain)
Technology Class: Likely related to pharmaceutical compositions, drug delivery systems, or molecular entities, per WIPO’s classification (typically IPC A61K or similar).
The WIPO publication indicates a strategic early-stage patent application targeting novel chemical entities, formulations, or delivery mechanisms, with the goal of broad territorial coverage through PCT.
Scope of the Patent
1. General Scope:
The patent primarily aims to secure rights over specific chemical compounds, pharmaceutical compositions, or methods of treatment that address certain medical conditions. Its scope encompasses an assembly of claims designed to cover:
- Novel chemical entities with therapeutic potential.
- Pharmaceutical formulations incorporating these entities.
- Methods of manufacturing or administering the compounds.
- Treatment methods for particular diseases or conditions.
2. Patent Claims Breakdown:
a. Claims Drafting Style:
- Independent Claims: Usually focus on broad chemical structures or methods.
- Dependent Claims: Narrower, referencing specific substituents, dosages, or combination therapies.
- Purpose: To maximize scope while maintaining defensibility.
b. Typical Claim Categories:
- Chemical Structure Claims: Define novel molecules with specific functional groups, stereochemistry, or substituents.
- Pharmaceutical Composition Claims: Cover formulations comprising the molecules, often including excipients, carriers, or delivery systems.
- Use Claims: Cover the method of treatment or prevention of particular diseases using the compounds.
- Method of Manufacturing: Claims describing synthesis routes.
3. Scope Analysis:
Given WIPO’s cautious drafting, the patent likely emphasizes broad chemical genus claims to secure extensive coverage across classes of compounds, reducing the risk of easy workaround and enabling later narrow patenting applications. The claims appear to claim:
- Specific molecular scaffolds with defined substituents.
- Variations to include different substituents to extend coverage.
- Therapeutic methods for disease treatment based on these compounds.
4. Breadth and Limitations:
The scope’s breadth depends on the chemical diversity covered and the specificity of the claims. Broad claims risk invalidation or challenge if prior art surfaces, while narrow claims risk being circumvented. WIPO’s strategy suggests an intent to balance these considerations, providing broad initial coverage with potential for narrowing through prosecution.
Patent Landscape Analysis
