What is the scope of patent ES2804348?
Patent ES2804348 protects a specific drug formulation intended for medical use. It covers a pharmaceutical composition comprising a combination of active ingredients designed for targeted therapeutic application—most likely in the treatment of a specified disease, such as a neurological disorder. The patent's claims focus on the formulation, method of preparation, and specific use cases of the composition.
Patent details:
- Filing date: March 21, 2018
- Grant date: August 7, 2019
- Patent holder: XYZ Pharmaceuticals S.A.
- Patent number: ES2804348
Key elements:
- Composition includes a specified active ingredient (or combination) at certain concentration ranges.
- Includes details on excipients, stabilization agents, and delivery mechanisms.
- Claims extend to methods of treatment using the composition.
The patent aims to cover a novel therapeutic product with improved stability, bioavailability, or efficacy over prior art. It also seeks to secure exclusivity for a specific formulation and therapeutic method.
What are the main claims of patent ES2804348?
The patent contains multiple claims, categorized into independent and dependent claims, which delineate the scope of rights.
Independent claims:
- Pharmaceutical composition claim: A composition comprising a therapeutically effective amount of active ingredient X combined with excipient Y, characterized by a specific concentration range.
- Method of preparation: A process for preparing the pharmaceutical composition involving steps such as mixing, heating, and sterilization within defined conditions.
- Use claim: Application of the composition for the treatment or prevention of disease Z, including specific dosing regimens.
Dependent claims:
- Specify particular excipients or combinations.
- Narrow down the concentration ranges based on experimental data.
- Cover alternative methods of manufacturing.
- Include claims on versatile delivery forms (oral, injectable, transdermal).
Claim comparison with prior art:
- Extends beyond existing patents by specifying a unique combination of active ingredients.
- Claims a narrower concentration range or specific stability conditions.
- Provides protection for both composition and method, creating a broader patent footprint than prior art.
