Overview of U.S. Patent 9,669,096
The patent is titled "Methods of treatment using selective 5-HT1B/1D receptor agonists," primarily related to compounds that selectively activate serotonin receptor subtypes 5-HT1B and 5-HT1D. These are known targets for antimigraine agents, with well-established therapeutic relevance.
The patent’s priority date is September 24, 2014, reflecting its filing in the context of rapidly evolving migraine therapeutics, especially following the emergence of triptan-based drugs and newer selective agonists.
Scope of the Patent
1. Technical Field and Focus
The patent delineates methods of treatment involving certain chemical compounds that act as selective 5-HT1B/1D receptor agonists. The scope encompasses both the chemical entities and their use in specific therapeutic applications—primarily, the treatment of migraine and related disorders.
2. Types of Claims
The patent contains multiple independent and dependent claims that define its legal scope.
a) Composition and Compound Claims
- Claims covering chemical compounds with specific structural features: e.g., a base scaffold with particular substituents optimized for receptor selectivity.
- Claims for pharmaceutical compositions comprising the claimed compounds and pharmaceutically acceptable carriers.
b) Method Claims
- Claims directed to methods of treating migraine, involving administering the compounds within specific dosage ranges.
- Some claims specify administration routes, formulations, or combination therapies.
c) Use Claims
- Claims covering the use of the compounds for producing a therapeutic effect, aligning with method claims but emphasizing the utility aspect.
3. Claim Construction and Limitations
The claims are generally narrower in scope owing to specific structural limitations, exemplified by the particular heterocyclic core and functional groups. The dependent claims further elaborate on variations, including substituent modifications, dosages, and formulations.
The broadest independent claim typically targets the recombinant compound class with a set of defining structural features, ensuring the patent covers core innovations but avoids overbreadth that could be challenged for lack of novelty or inventive step.
4. Patent Term and Priority
With a priority date in September 2014 and a typical 20-year term, the patent is set to expire around September 2034, providing ample time for commercial development and patent enforcement.
Patent Landscape and Related Intellectual Property
1. Competitive Landscape
The patent landscape surrounding 5-HT1B/1D receptor agonists is highly active, featuring multiple filings and issued patents.
- Pre-2017 Developments: Prior art includes triptan class drugs (e.g., sumatriptan), which largely targeted the same receptor system but with broader activity profiles and less selectivity.
- Post-2017 Patents: Subsequent filings often focus on compounds with increased receptor selectivity, improved pharmacokinetics, or reduced side effects.
2. Overlaps and Differentiation
The 9,669,096 patent differentiates itself through:
- Specific structural modifications enhancing selectivity.
- Demonstrated efficacy in treatment protocols.
- Potential advantages over prior art compounds, such as fewer adverse effects or improved pharmacodynamics.
3. Patent Families and Extensions
Patents family members are geographically filed across jurisdictions, including Europe (via EPO filings), Japan, and China, forming a protective patent ecosystem. Supplementary patents may include formulation patents or method-of-use patents extending the protection scope.
4. Legal and Enforcement Considerations
Given its claims and structural novelty, the patent provides enforceable rights for its inventors and assignees. However, validity challenges could arise from prior art references, especially considering the longstanding research on triptan-related compounds.
Implications of the Patent’s Scope
The scope of claims, centered on selective 5-HT1B/1D receptor agonists and their therapeutic applications, positions it as a critical foundational patent in narrow-spectrum migraine treatment drugs. Its enforceability, combined with its strategic patent family network, fortifies the holder’s market position.
