EP3679941 is a European patent granted by the European Patent Office (EPO) related to a proprietary drug or therapeutic method. The patent’s scope, claims, and landscape provide insights into its competitive positioning and technological innovation.
What Is the Scope of EP3679941?
EP3679941 broadly protects a specific chemical entity, combination, or method relevant to a therapeutic indication. Its scope is defined primarily by its claims, which specify the protected subject matter.
The patent has claims focusing on:
- The chemical structure of a novel compound.
- Specific chemical derivatives or analogs.
- Methods of use or administration.
- Pharmaceutical compositions containing the claimed compound.
The scope limits third-party activities primarily to non-infringing uses of the compound or methods described. The patent claims aim to prevent generic development of identical or closely related compounds or methods.
What Are the Key Claims of EP3679941?
The patent includes independent claims that establish broad protection. Typical claims include:
-
Compound Claim:
A chemical compound with a specific core structure, optionally substituted at defined positions. For example, a novel heterocyclic compound with pharmacologically active groups.
-
Method of Use:
A method for treating a specified disease or condition using the compound. This generally involves administering an effective amount of the compound to a patient.
-
Pharmaceutical Composition:
A combination of the compound with excipients suitable for pharmaceutical use.
-
Manufacturing Process:
Processes for synthesizing the compound, involving specific chemical steps or conditions.
The claims’ scope ranges from very broad (covering all compounds with the core structure) to narrower (specific derivatives or formulations). The breadth depends on the filing strategy and prior art considerations.
