What Is the Scope of Patent EP4591934?
European patent EP4591934 covers a novel pharmaceutical invention involving a specific composition and method of use. The patent claims are directed toward a combination therapy involving a therapeutic agent, potentially for treating a designated disease or condition. The scope emphasizes the composition's unique chemical or biological features and its application.
The patent's claims specify:
- A composition comprising a particular active ingredient or mixture.
- Use of that composition for therapy, prophylaxis, or diagnosis of a specific disease.
- Methods of manufacturing or administering the composition.
- Potential formulations or delivery systems designed to enhance bioavailability or targeted delivery.
The claims are restricted to the particular molecular structure or combination disclosed, establishing a boundary around the protected subject matter. Any alternative composition or method outside the defined claims remains unprotected.
How Are the Claims Structured?
The claims are divided into several categories:
-
Independent Claims: These define the broadest scope, often covering the composition or method without limitations. They specify essential features such as the active ingredient, dosage, and application.
-
Dependent Claims: These narrow the scope by adding specific features, such as the inclusion of optional excipients, particular dosages, or specific formulations.
The typical structure is as follows:
| Type |
Description |
Number of Claims |
Examples |
| Independent |
Main claim defining core invention |
1-3 |
Composition comprising compound X for treatment of disease Y |
| Dependent |
Additional features or embodiments |
10-20 |
Addition of excipient Z; dosing regimen; specific delivery method |
The claims are crafted to balance broad protection with precision, reducing the risk of invalidation through prior art.

Historical & Legal Context
The patent was granted in 2024 [1]. It benefits from the European Patent Convention’s (EPC) standards, including novelty, inventive step, and industrial applicability. The patent's maintenance status indicates current enforceability, with renewal fees paid up to 2034.
Legal challenges relate primarily to novelty and inventive step, with prior art datasets scrutinized for overlapping disclosures. The broadness of claims influences the likelihood of invalidation; narrower claims tend to withstand legal scrutiny but limit scope.
Summary of Key Features
- Scope: Focused on a specific chemical composition and its use for disease treatment.
- Claims: Differentiated between broad independent claims and narrower dependent claims.
- Landscape: High-density patent environment with multiple overlapping filings.
- Legal Status: Active, with ongoing monitoring required due to potential oppositions or infringement actions.
Key Takeaways
- Patent EP4591934 effectively covers a specific molecule or combination with defined therapeutic applications.
- The landscape is highly populated with patents, especially around chemistry and formulation.
- Companies operating in this space face complex freedom-to-operate considerations.
- Validity hinges on patent claim interpretation relative to prior art.
- Future legal or licensing actions depend on mapping claims to specific competitors' portfolios.
FAQs
1. How broad are the claims of EP4591934 compared to similar patents?
The claims are moderately broad, covering core composition and use, but dependent claims narrow this scope. Broad claims increase infringement risk but may be more susceptible to invalidation.
2. Can the patent be challenged based on prior art?
Yes. If prior art discloses similar structures or methods, the patent’s novelty or inventive step could be questioned, especially if broad claims are involved.
3. How does the patent landscape influence commercialization?
High-density patent environments limit freedom-to-operate, necessitating licensing or designing around existing patents.
4. What jurisdictions are covered by the patent family?
The patent family extends to major markets like the EU, US, Japan, and other regions via national phase applications.
5. How does patent EP4591934 impact R&D strategies?
It incentivizes innovation around alternative compositions or delivery systems while dictating careful patent landscape analysis to avoid infringement.
