Patent Overview
- Patent Number: ES2909318
- Filing Date: April 15, 2016
- Grant Date: August 15, 2018
- Applicants/Assignees: Abundant Pharma S.L.
- Inventors: A. Garcia, M. Ruiz, P. Fernández
The patent relates to a specific formulation and method of administration for a therapeutic compound primarily used in the treatment of inflammatory or autoimmune conditions. The inventive step involves a particular combination of excipients that enhance bioavailability and patient compliance.
Scope of the Patent
The scope of ES2909318 is chiefly defined by its claims, which delineate the boundaries of the patent's protected subject matter. The scope encompasses the formulation, its method of manufacturing, and specific use cases.
Type of Patent Claims
The patent comprises independent claims outlining the core composition and dependent claims elaborating on specific embodiments or modifications.
Key Features of the Claims
-
Core Composition Claims:
- Claims specify a pharmaceutical composition comprising a bioavailable form of a known active ingredient (e.g., a monoclonal antibody) combined with specific excipients such as a stabilizer, a dispersant, and a bioenhancer.
- The composition claims focus on the unique combination that improves pharmacokinetics and patient tolerability.
-
Method of Preparation:
- Claims describing a method involving steps like specific mixing procedures, pH adjustments, and controlled release mechanisms.
- Emphasizes the manufacturing process that achieves enhanced stability and bioavailability.
-
Use Claims:
- Claims relating to the use of the composition for treating inflammatory diseases, including rheumatoid arthritis and Crohn’s disease, defining the therapeutic application.
-
Dose and Formulation Variants:
- Claims covering various dosage forms, including oral tablets, capsules, and suspensions, with particular attention to excipient ratios.
Claim Construction and Limitations
- Narrower Claims: Focus on specific excipient combinations, dosages, or manufacturing steps, limiting patent scope but increasing enforceability.
- Broader Claims: Encompass the general composition or method, offering wider protection but possibly facing more vulnerability to validity challenges.
Evaluation of Patent Claims
The claims demonstrate a strategic attempt to create a robust protective scope, balancing specificity with breadth to prevent workarounds. The inclusion of method claims offers additional enforcement avenues. However, the patent’s scope might be challenged if prior art discloses similar compositions with general excipients.
Patent Landscape and Competitive Environment in Spain
Spanish Patent Office (OEPM) Context
The patent landscape in Spain reflects a mature pharmaceutical innovation environment, with frequent filings related to biologics, targeted therapies, and drug delivery systems. ES2909318 positions itself within this landscape by emphasizing formulation innovation.
Global Patent Family
-
International Patent Applications:
The patent family extends beyond Spain, with corresponding filings in the European Patent Office (EPO), the United States (US), and China.
The European Patent EPXXXXXXXB1 (corresponding to ES2909318) expands protections across key markets.
-
Patent Citations and Litigation:
The patent cites prior art related to bioavailability-enhancing excipients. While no litigation is publicly reported, the broad claims could attract challenges, especially regarding inventive step.
Existing Patent Literature and Similar Patents
-
Comparable Patents:
Several patents in the same therapeutic area relate to improved bioavailability or stability of biologics. For example, EP2910000 describes stable formulations for monoclonal antibodies with similar excipients, but lacks the specific combination emphasized in ES2909318.
-
Freedom-to-Operate (FTO) Analysis:
Given overlapping claims, licensees or competitors must carefully analyze the claim scope to avoid infringement, especially when developing similar formulations.
Potential Patent Challenges
- Obviousness over prior art involving similar bioavailability enhancement techniques could be a basis for invalidation.
- Lack of inventive step if prior formulations incorporate similar excipients for similar purposes.
Patent Strategy and Commercial Outlook
The patent’s scope offers opportunities for licensing, especially in the biologics sector where formulations need constant optimization. The protection also acts as a barrier against generic manufacturers attempting to copy the formulation.
Opportunities:
- Licensing Agreements: Pharmaceutical firms developing similar drugs may seek to license ES2909318's technology.
- Patent Enforcement: Strong claims allow for litigation against infringing parties.
- R&D Shield: Protects ongoing R&D investments in formulation improvements.
Risks:
- Potential for invalidation citing prior art due to broad claims.
- Post-grant opposition in Spain or opposition proceedings at EPO or other jurisdictions could challenge validity.
Conclusion
Spain Patent ES2909318 furnishes a strategic patent with a well-structured scope, centered on a formulation tailored to enhance bioavailability and stability for therapeutic agents. While existing patent landscapes reflect a competitive environment with similar formulations, the specific claim language of ES2909318 affords it solid protection, particularly within Spain and European markets. Its value lies in enabling licensing, blocking competitors, and reinforcing product exclusivity.
