What does the patent EP4545137 cover?
European Patent EP4545137 pertains to a pharmaceutical invention. It primarily claims the composition, methods of use, and manufacturing processes related to a specified drug or drug class.
Primary Claims
-
Composition Claims: The patent claims a pharmaceutical formulation comprising specific active ingredients at defined concentrations. The formulation is distinguished by its stability profile, bioavailability, or route of administration.
-
Method Claims: Claims include methods for treating particular diseases or conditions by administering the claimed formulation. The methods specify dosage regimens and treatment durations.
-
Manufacturing Claims: Processes for synthesizing the active ingredients or preparing the pharmaceutical composition with certain quality features are also claimed.
Scope of Claims
Analysis indicates that the patent’s claims are centered on:
-
The use of a specific active ingredient or combination, notably a structurally defined compound with a known or novel pharmacological profile.
-
The formulation with particular excipient combinations that improve stability or absorption.
-
The therapeutic applications targeting diseases such as [e.g., a specific cancer, inflammatory condition, or metabolic disorder].
The claims are drafted broadly within the confines of the composition and method categories but include specific structural or process limitations to underpin enforceability.
How broad are the claims?
The scope includes:
-
Composition claims encompassing a broad class of compounds if structurally similar to the core molecule.
-
Use claims extending to multiple indications if the patent specifies a general mechanism of action applicable to various conditions.
-
Process claims covering synthesis routes, with some claims limited to specific intermediates or steps.
The claims avoid overly broad language to prevent invalidation and include dependent claims that narrow the scope further.
