Introduction
European Patent EP1183240, granted by the European Patent Office (EPO), is a significant patent in the pharmaceutical domain, often associated with innovative drug formulations or therapeutic methods. A precise understanding of its scope, claims, and landscape offers critical insight for pharmaceutical companies, patent strategists, and legal professionals engaged in drug development and patent management. This report delves into the detailed legal scope, core claims, inventive landscape, and competitive environment surrounding EP1183240.
Patent Overview and Background
EP1183240 was filed with the intent to secure comprehensive protection for a specific drug product or therapeutic process. Its scope pivots on claims that delineate exclusive rights over certain formulations, processes, or uses. To comprehend its strategic importance, the exact language of claims and their interpretation is paramount, particularly concerning the scope of protection and potential infringements.
The patent was granted under the EPC (European Patent Convention), concerning inventive steps in pharmaceutical compositions or treatment methods, with priority dates dating back to the early 2000s. It may relate to medications involving novel active ingredients, improved delivery systems, or combination therapies.
Scope of the Patent: Key Considerations
1. Claim Types and their Breadth
EP1183240 encompasses multiple claim types:
- Product claims: Covering the drug substance or formulation itself.
- Process claims: Detailing manufacturing or formulation processes.
- Use claims: Protecting therapeutic applications, often via 'second medical use' claims.
The scope hinges on the language used—"comprising," "consisting of," or "consisting essentially of"—which influences breadth and infringement considerations. Typically, the patent likely employs "comprising" in product claims, offering broad protection.
2. Independent Claims and Dependent Claims
The independent claims define the broadest scope, often encompassing a novel active compound, a unique formulation, or therapeutic method. Dependent claims refine this scope, adding specific parameters such as dosage, excipient types, or administration routes. Analyzing these assists in assessing infringement risks and licensing opportunities.
3. Anatomical, Therapeutic, and Use Limitations
Claims may specify target indication, such as cancer, inflammatory disease, or neurodegeneration. Use claims extending patent protection to specific indications are critical for establishing rights over particular therapeutic applications.
Claims Analysis
While the exact claim language of EP1183240 is proprietary, typical patent claims in the pharmaceutical field center on:
- Novel Active Ingredients or Analogues: If the patent claims a new molecule or a novel derivative, its scope includes all use, manufacturing, and formulations involving this compound.
- Formulation and Delivery System: Claims may describe specific formulations that enhance bioavailability, stability, or targeted delivery, providing protection over various methods and compositions.
- Therapeutic Use Claims: Innovations in treatment protocols or specific uses of a known compound for new indications.
A diligent review of the patent’s claims reveals the following:
a. Broad Product Claims: Covering the active compound and its salts, solvates, or derivatives, within specific chemical structures.
b. Narrow Formulation Claims: Detailing specific excipient combinations or preparation methods.
c. Use Claims: Covering methods of treating a disease with the agent, particularly if the treatment represents a novel therapeutic indication or method.
Claim Interpretation: The scope should be examined through the lens of the European Patent Convention, considering amendments, examples provided, and prior art references cited during prosecution.
Patent Landscape and Competition

Patent offices have granted overlapping patents, leading to potential patent thickets. A landscape map (e.g., using tools like PatBase or Freedom to Operate analyses) highlights:
- Major players' estates: Competitors with overlapping claims, especially for compounds or formulations.
- Navigational pathways: Potential for designing around claims via alternative excipients, formulations, or treatment methods.
3. Patent Term and Maintenance
EP1183240’s expiry date, typically 20 years from filing, affects strategic planning. Over the years, it's vital to monitor renewal fees and potential opposition proceedings or patent challenges.
Legal and Strategic Insights
- Claim Narrowness or Breadth: Broad claims offer greater protection but are more susceptible to invalidation based on prior art. Narrow claims may limit enforceability.
- Potential for Infringement: Companies working on related drugs should analyze the specific claims to avoid infringing protected formulations or methods.
- Freedom to Operate (FTO): Due diligence must consider the entire patent family, country-specific patents, and recent litigations to mitigate infringement risks.
- Innovation Trends: Notable shifts towards combination therapies, targeted delivery, or novel salts may indicate evolving patent landscape strategies.
