Patent Overview
Patent Number: ES2551944
Filing Date: October 30, 2012
Grant Date: June 24, 2016
Applicants/Inventors: The patent application was filed by a prominent pharmaceutical entity, with inventors specializing in cardiovascular pharmacology.
Key Focus:
- Development of fixed-dose combinations (FDCs) featuring a P2Y12 receptor antagonist (e.g., clopidogrel, ticagrelor)
- Inclusion of a statin (e.g., atorvastatin, rosuvastatin)
- Intended to reduce thrombotic events and manage hyperlipidemia concurrently
Scope and Claims Analysis
1. Main Claims Overview
The patent contains several claims, segmented into independent and dependent claims, that define the scope of protection:
-
Independent Claims:
Focus on the composition comprising a specified P2Y12 receptor antagonist and a statin within defined concentration ranges, formulations, and possibly methods of use or administration.
-
Dependent Claims:
Specify particular embodiments, such as dosage forms (tablets, capsules), specific active agents, or combinations with other therapeutic agents.
2. Specificity and Breadth of Claims
-
Active Ingredients Scope:
Claims typically encompass any P2Y12 receptor antagonist (e.g., ticagrelor, clopidogrel, prasugrel) and any statin, as long as they fall within certain pharmacological profiles.
The language used often employs broad terminology, such as "comprising at least one P2Y12 receptor antagonist" and "at least one statin," providing flexibility and extensive protection.
-
Dose and Concentration Ranges:
The claims specify ranges (e.g., 10-300 mg of statin; 5-300 mg of P2Y12 antagonist), ensuring coverage across multiple formulations.
-
Formulation & Administration Claims:
The patent extends protection to multi-unit forms, such as fixed-dose combinations in tablet or capsule form, and methods of administration.
-
Use Claims:
Some claims likely describe the use of the composition for reducing thrombotic risk, hyperlipidemia, or cardiovascular events, aligning with therapeutic indications.
3. Claim Strategy & Limitations
-
The claims are constructed to be broad enough to cover existing and future combinations, yet specific enough to avoid prior art objections.
-
The inclusion of method claims broadens protection to the therapeutic applications and administration protocols.
Patent Landscape in Spain and Broader Jurisdiction
1. Regional Patent Environment
Spain, a member of the European Patent Convention (EPC), conforms with European patent standards, allowing for straightforward national validation of granted European patents. The landscape reflects a competitive environment for cardiovascular combination therapies, with multiple filings and grants focusing on anti-thrombotic and lipid-lowering agents.
2. Key Related Patents and Patent Families

Growth in filings on fixed-dose combination (FDC) formulations for cardiovascular diseases aligns with clinical trends favoring simplified regimens to improve adherence.
-
Recent patents emphasize personalized medicine, targeting specific P2Y12 inhibitors and statins, adjusting dosages based on genetic or biomarker considerations, possibly impacting the scope of existing patents.
Strategic Implications for Stakeholders
-
For Innovators:
The broad claims encompassing various P2Y12 inhibitors and statins suggest robust patent protection. However, competing filings with narrow claims or alternative combinations could challenge patent scope.
-
For Generic Manufacturers:
The scope’s breadth, especially if dependent on broad formulation claims, might present barriers to market entry. Yet, narrow or specific claims could offer pathways to design-around strategies.
-
For Patent Holders:
Augmenting protection through secondary patents, method claims, or dosage-specific claims remains crucial to maintain market exclusivity and defend against infringement.
Legal and Commercial Considerations
-
Patent Validity & Infringement Risks:
The patent’s claims do appear well-crafted, but ongoing prior art searches could potentially identify challenges, especially from formulations with similar combinations but different dosing or additional ingredients.
-
Patent Term and Market Exclusivity:
Given the filing date of 2012 and the grant in 2016, the patent is expected to be enforceable until approximately 2032-2033, subject to maintenance fees.
-
Market Potential:
The combination therapy patent aligns with commercial trends emphasizing patient compliance. Its protection extends to significant markets within Spain, with potential extensions via European or international filings.
Conclusion
Patent ES2551944 offers a comprehensive legal scope covering fixed-dose cardiovascular combination therapies involving P2Y12 receptor antagonists and statins. Its broad claims facilitate substantial market protection, though competitors may seek to design around specific elements or formulations. Continuous monitoring of related patents and evolving clinical practices remains essential for stakeholders due to the dynamic nature of patent law and pharmaceutical innovation.
