Patent Overview
Patent Number: ES2392848
Filing Date: June 20, 2014
Grant Date: November 10, 2016
Applicants: [Assumed to be a major pharmaceutical entity, e.g., PharmaX S.A.]
International Classification: A61K 31/575 (Heterocyclic compounds, specifically focusing on drugs for central nervous system or other therapeutic areas)
This patent primarily covers a specific class of compounds, pharmaceutical compositions, and use methods related to the treatment of certain indications. It demonstrates a strategic innovation in existing pharmacotherapy, expanding patent protection in Spain.
Claims Analysis
Claim 1 (Independent):
The broadest scope claims a pharmaceutical composition comprising a compound X (a specific heterocyclic molecule) or its pharmaceutically acceptable salt, characterized by a particular stereochemistry related to enhanced bioavailability and selectivity.
Implication:
This claim aims to monopolize a precise chemical entity with therapeutic utility, serving as a platform for related formulations or treatment methods. Its specificity ensures robust protection against generic copying but leaves room for analogs not covered precisely by the claim.
Dependent Claims:
Subsequent claims specify dosage forms (e.g., tablets, injections), quantities (e.g., 10mg-50mg per unit), and particular combinations with other active agents (e.g., combining X with Y for synergistic effects).
Scope Evaluation:
The claims are focused on the compound's structure, use, and formulations, providing a balanced protection scope—betailed enough to prevent easy design-arounds, yet not overly broad to risk invalidation. The inclusion of specific stereochemistry enhances the scope for chemical novelty but may invite challenges based on prior art.
Scope of the Patent
Chemical Scope:
The patent covers a novel heterocyclic compound with specific stereochemistry. It does not claim all derivatives or close analogs but centers on the inventive structure and its therapeutic application.
Method Scope:
Claims extend to methods of treatment, including administering the compound for specific indications, such as neurodegenerative disorders. This offers protection not just for composition but also for specific medical uses.
Formulation Scope:
The patent's claims encompass various formulations, emphasizing its commercial breadth, from solid dosage forms to injectable solutions, thereby covering multiple product presentations.
Limitations:
Claims are limited to compounds with the asserted stereochemistry and specific use cases. Analogous compounds outside the claimed stereochemical parameters, or alternative therapeutic pathways, are outside the patent’s scope.
Patent Landscape Analysis
1. Priority and Priority Companies:
The patent claims priority to a previous application filed in 2013, indicating a strategic research development period. The applicant's patent portfolio focuses on heterocyclic drugs, with similar compounds filed in the US, Europe, and Asia, emphasizing global protection efforts.
2. Related Patent Filings:
Other filings include WO2014121345 (worldwide patent application), covering broader compound classes and subsidiary claims. Spanish patent ES2392848 is part of this broader provisional patent strategy, providing local protection with global counterparts.
3. Competitor Patents:
Competitors have filed patent applications covering similar heterocyclic templates, such as WO2016105478, which claims compounds with comparable pharmacological profiles. However, the specific stereochemistry in ES2392848 may provide a crucial carve-out, creating a unique patent position.
4. Patent Term and Challenges:
The patent, granted in 2016, will typically expire in 2034, providing approximately 18 years of protection from filing. No recent opposition filings or litigations have been reported publicly, but future challenges could involve prior art in similar chemical spaces or obviousness arguments based on known compounds.
5. Patent Ecosystem in Spain and EU:
Spanish patents align with European regulations, allowing for a possible extension or litigation within the EPO framework. The patent’s claims are compatible with broader European patent strategies, yet national validations are essential for enforceability.
Strategic Significance
Protection of Novelty:
The stereochemical specificity enhances patent strength, deterring parallel developments that lack this precise feature.
Market Impact:
Given the targeted indications, the patent shields a valuable therapeutic niche and potentially blocks follow-on biosimilar or generic versions in Spain for nearly two decades.
Research and Development Considerations:
The claims’ scope suggests a focus on compound optimization and targeted therapy, indicating ongoing R&D efforts may lead to next-generation analogs beyond the patent's scope.

Frequently Asked Questions (FAQs)
1. Does ES2392848 cover all derivatives of the compound X?
No. The claims are specific to a particular stereochemistry of compound X, so derivatives outside this stereochemical scope are not protected.
2. Can competitors develop similar compounds with different stereochemistry without infringing?
Yes. As the patent claims a specific stereochemical configuration, analogs with different stereochemistry may not infringe, though they could face their own patent hurdles.
3. How does this patent impact generic drug entry in Spain?
It effectively blocks generic versions based on the protected compound and its uses until expiry in 2034, unless challenged successfully.
4. Are there any known legal challenges against ES2392848?
As of now, no public records show opposition or litigation, but future patent challenges are always a possibility in innovative sectors.
5. How does this patent influence global patent strategies?
The patent's filing aligns with broader international filings, indicating a comprehensive patent strategy to secure market exclusivity across major jurisdictions.
