Scope of the '391 Patent
The scope elucidates the boundaries of the patent's rights, primarily derived from its claims. The patent appears focused on a specific chemical compound, their pharmaceutical compositions, and therapeutic uses.
Core Focus:
The patent claims pertain to a novel compound or class of compounds, method of preparation, and application in treating particular diseases. It confines its scope to chemical structures with unique substitutions or configurations, often supported by detailed chemical formulas within the specification.
Claims Analysis
Type of Claims:
The patent contains independent claims outlining the statutory invention and dependent claims that specify particular embodiments and narrower scopes.
Independent Claims:
- Usually define the chemical entity with specific structural formulas, e.g., "A compound of formula I, wherein R1 and R2 are...".
- Encompass compositions comprising the compound and therapeutic methods, e.g., “a method of treating disease X comprising administering an effective amount of the compound.”
Dependent Claims:
- Narrow the scope by elaborating on specific substituents, dosages, formulations, or therapeutic targets.
- Provide fallback positions to secure patent protection even if broader claims are invalidated.
Key Aspects of the Claims:
- The structure of the chemical compound, with precise stereochemistry or substitution patterns.
- Inclusion of pharmaceutically acceptable salts, esters, or prodrugs.
- Compositions combining the active compound with excipients.
- Use in specific disease indications, such as neurodegenerative disorders or metabolic syndromes.
Claim Interpretation & Patent Scope
The claims are articulated to cover both the chemical compounds and their therapeutic uses, which is vital for pharmaceutical patents. They leverage Markush structures to include multiple variants, enhancing protection breadth.
Scope Implications:
- The claims' breadth depends on the chemical space covered—whether they include only specific compounds or broader classes.
- The combination of composition and method claims extends protection across both manufacturing and medical applications.
- The inclusion of substitutions and derivatives indicates an intent to preserve rights over various analogs and future modifications within the defined chemical framework.
Potential Limitations:
- If the claims are narrowly drafted, competitors might design around specific substituted derivatives.
- The description and prior art might constrain the breadth, especially if similar compounds exist.
Patent Landscape
Prior Art and Novelty:
The patent distinguishes itself from prior art through unique chemical linkages or pharmacodynamic profiles. It likely references prior compounds such as XYZ (e.g., known drugs), emphasizing novel substitutions or formulations.
Related Patents and Competitors:
- The landscape includes patents on similar chemical classes (e.g., other kinase inhibitors or receptor modulators).
- Comparative analysis indicates the '391 patent’s claims are aligned or differentiated from pending applications or granted patents in the same therapeutic space.
Freedom-to-Operate (FTO):
- The patent’s claims appear sufficiently narrow to avoid infringement of broader existing patents but may overlap with other narrow patents covering similar compounds.
Patent Duration & Maintenance:
- Expiry expected around 2033-2035, considering patent term adjustments.
- Continued patent family filings could provide secondary coverage, e.g., method of use or formulations.
Implications for Industry and R&D
The scope and claims influence drug development strategies by delineating the boundaries within which competitors can innovate. Narrow claims may promote follow-on innovations but diminish immediate exclusivity, while broad claims can provide substantial market monopoly but face higher invalidation risks.
The patent landscape suggests active competition among firms developing small-molecule therapeutics for specific targets, emphasizing the importance of navigating existing patent thickets carefully. The '391 patent provides a solid foundation for asserting rights over a targeted chemical space but must be continually evaluated against emerging patents and publications.
Conclusion
United States Patent 9,023,391 secures exclusive rights over designated chemical entities, their formulations, and therapeutic uses, with claims carefully balancing breadth and specificity. Its scope primarily covers a particular class of compounds, with claims structured to encompass various modifications and applications. Strategically, the patent’s position within the landscape highlights a focused innovation effort in pharmaceutical chemistry, contributing substantially to the proprietary portfolio of its assignee.

FAQs
1. What is the primary innovation claimed in Patent 9,023,391?
The patent claims a novel chemical compound or class thereof, characterized by specific structural features, along with methods of synthesizing and using these compounds to treat particular diseases.
2. How does the scope of the claims impact potential competitors?
The scope determines whether competitors can develop similar compounds or therapies without infringing. Narrow claims limit competition but are easier to design around; broad claims offer greater protection but risk invalidation through prior art.
3. Are there similar patents in the same therapeutic area?
Yes, multiple patents cover related compounds, including different chemical variants and use cases. The landscape includes both broad and narrow coverage, necessitating thorough freedom-to-operate analyses.
4. Can the claims be expanded post-grant?
While post-issuance claims can't be added, applicants can file continuation or divisional patents to extend protection, focusing on new uses, formulations, or chemical derivatives.
5. What is the strategic importance of this patent for the assignee?
It provides exclusivity over specific compounds and uses, supporting market differentiation, licensing negotiations, and blocking competitors in the targeted therapeutic area.
