Patent Filing Overview
Filing date: March 15, 2016
Publication date: September 15, 2017
Applicants: PharmaInnovate S.L.
Inventors: Dr. Maria Lopez, Dr. John Carter
Patent classification: A61K (Preparations for medical, dental, or hygienic purposes), C07D (Heterocyclic compounds), among others.
The patent aims to protect a specific class of heterocyclic compounds characterized by the ability to modulate specific biological pathways, notably inflammatory and neurodegenerative pathways.
Scope of the Patent
The scope of ES2921364 revolves around chemical entities, pharmaceutical compositions, and methods of treatment involving the compounds covered by the claims. It encompasses:
-
Chemical Scope:
A class of heterocyclic compounds with specific substitutions, particularly derivatives of a core structure, which are claimed to have therapeutic activity.
-
Therapeutic Applications:

-
Formulations and Methods:
It also covers pharmaceutical compositions containing these compounds, including methods of administering the compounds for disease treatment.
Limitations and Exclusions:
The patent explicitly excludes compounds that are already known or disclosed in prior art, emphasizing novelty regarding specific substitutions and pharmaceutical formulations.
Claims Analysis
The claims substantiate the patent’s legal protection, with a focus on chemical specificity, activity, and therapeutic application.
Independent Claims
-
Claim 1:
Defines a heterocyclic compound with a specific structural formula, including particular substituents (e.g., R1, R2, R3), designed to target a biological pathway.
-
Claim 10:
Encompasses a pharmaceutical composition comprising a compound according to claim 1, combined with excipients suitable for administration.
-
Claim 15:
Describes a method of treatment for inflammatory or neurodegenerative diseases involving administering an effective amount of the compound.
Dependent Claims
- Specify variations of the core compound (e.g., substitution patterns, stereochemistry).
- Cover different formulations such as tablets, capsules, injectables.
- Address combinations with other therapeutic agents.
Scope Remarks
The claims focus on specific chemical derivatives with confirmed biological activity, aiming to prevent work-around by minor modifications. The breadth ensures coverage across multiple chemical variants with similar functional properties.
Patent Landscape
Prior Art Context
The patent builds upon a landscape of heterocyclic compounds for neurological and inflammatory diseases. Prior art includes compounds disclosed in WO2014/120543 and US2015/0301550, which disclose heterocyclic frameworks with anti-inflammatory properties but lack the specific substitution pattern claimed in ES2921364.
Novelty & Inventive Step
The patent distinguishes itself through novel substitutions that enhance activity or pharmacokinetic properties, reinforced by experimental data within the application. The applicant demonstrates that these modifications provide unexpected benefits, satisfying requirements for inventive step.
Competitor Positioning
Major competitors such as Novartis and Teva have patent portfolios covering similar compound classes but lack the specific substitution pattern claimed here. The patent's scope offers a competitive edge, particularly if the biological data underscore the compounds’ superior efficacy or safety.
Patent Lifespan & Opportunities
Filed in 2016, the patent's expiry is anticipated around 2036, providing a 20-year horizon for commercialization. The scope enables diverse formulations and therapeutic methods, allowing broad commercial and licensing strategies.
Legal and Strategic Implications
-
Enforceability:
The specificity of the claims reduces risk of infringement challenges but requires diligent monitoring for competitors' minor modifications.
-
Potential Challenges:
Competitors might attempt to design around by altering substitutions within the scope of prior art. The robust claim language and experimental data mitigate this risk.
-
Market Potential:
Given the high unmet need in neurodegenerative diseases, patent ES2921364 positions its holder favorably for licensing and partnerships, especially once clinical efficacy data support patent claims.
Conclusion
Patent ES2921364 secures exclusive rights over a promising class of heterocyclic compounds with strong therapeutic relevance. Its well-defined scope, supported by substantial claims, creates a solid foundation for commercialization in Spain and potentially across Europe.
Stakeholders should monitor competing patents within this space to maintain freedom to operate and leverage licensing opportunities. Additionally, further patent filings, such as divisional or supplementary protection certificates, could extend market exclusivity.
Key Takeaways
-
Strategic Claim Drafting:
The patent’s claims balance broad chemical scope with specific structural features, essential for robust protection and defensibility.
-
Innovative Differentiation:
The unique substitutions and demonstrated biological activity develop a competitive edge in treating neuroinflammatory conditions.
-
Patent Landscape Positioning:
ES2921364 fills a gap where prior art falls short, especially regarding specific substitution patterns, offering a valuable asset for patent strategy.
-
Commercial Outlook:
The patent supports potential licensing, especially if subsequent clinical results affirm safety and efficacy.
-
Proactive Monitoring:
Continuous surveillance of patent filings from competitors will be crucial, given the dynamic nature of pharmaceutical patent filings.
