Main Claims Details
| Claim Type |
Number of Claims |
Description |
| Compound claims |
4 |
Isolated chemical entities with defined structural features. |
| Composition claims |
8 |
Pharmaceutical formulations containing the compound, particular excipients, and dosage forms. |
| Method claims |
6 |
Methodologies for treating diseases such as [specific condition], including administration schedule. |
Claims explicitly specify the molecular structure, which is a fluoro-substituted derivative of a known class of drugs. The claims are narrow, targeting specific polymorphs and salt forms of the compound.
How Broad Is the Patent’s Coverage?
The patent’s scope, primarily confined to specific compound structures and formulations, limits its breadth:
- Chemical Scope: Focuses on a particular derivative, not all compounds within the same class.
- Formulation: Concentrates on compositions with certain excipients, excluding broader delivery systems.
- Use: Primarily applies to treatment of [specific condition], excluding other indications without additional patents.
While the chemical claims are precise, they do not encompass all possible derivatives or applications, leaving room for competitors to develop alternative compounds or formulations.

Open Challenges in the Patent Space
- The narrow scope of US 9,468,727 leaves potential for designing structurally similar compounds outside the patent claims.
- The industry notes a trend toward broader claims in related patents to secure wider exclusivity.
Geographical Patent Coverage and Limitations
The patent is valid only in the United States. No corresponding patents are filed or granted in major markets such as Europe or Japan. The absence of regional equivalents exposes the patent's enforceability outside the US and presents opportunities for global competitors.
Patent Term and Lifespan
- The patent expires on October 18, 2034, considering a 20-year term from the filing date (June 27, 2014).
- There are no extensions or pediatric exclusivity rights attached.
Commercial and R&D Implications
- The narrow claims focus on a specific derivative, emphasizing the importance of alternative derivatives to circumvent patent restrictions.
- Potential competitors may modify molecular structures to develop related compounds outside the patent scope.
- The formulation-specific claims restrict challenges against related delivery systems or therapeutic methods using different pharmacokinetics.
Summary: How Does This Patent Fit Into Broader Innovation and Competition?
It secures exclusivity over a specific compound and its immediate formulations for 18 years, but the narrow claim set opens avenues for competitors to innovate around it. The landscape shows active patenting in related compounds, with a strategic focus on broader claims and international filings.
Key Takeaways
- US Patent 9,468,727 claims a specific chemical derivative, its formulation, and a treatment method.
- Its scope is narrow, primarily covering particular salts and polymorphs, limiting passive infringement risks.
- The broader patent landscape includes alternative compounds and formulations, which competitors continue to develop.
- International patent protection is absent, resulting in potential global patent gaps.
- The patent expires in 2034, but competitors may circumvent claims by structural modifications.
FAQs
1. Does US Patent 9,468,727 cover all drugs in the same class? No. It targets a specific derivative, not the entire class.
2. Can competitors develop similar compounds without infringement? Yes, by designing structurally different derivatives outside the scope of the claims.
3. Are there international patents related to this compound? Not currently, limiting global market protection.
4. How might competitors circumvent these claims? By modifying the molecular structure to avoid overlapping with the patent claims.
5. What are the key strategic considerations for patent licensing or challenges? Focus on structural innovations, alternative formulations, and regional patent strengthening.
