What Is the Scope of Patent ES2684322?
Patent ES2684322 relates to a pharmaceutical composition designed to treat or prevent specific conditions. The scope is defined primarily by claims covering a combination of active ingredients, their ratios, and methods of use.
The patent claims focus on a composition comprising a first compound, such as a known therapeutic agent, combined with a second compound that enhances efficacy or reduces side effects. The patent explicitly claims formulations, dosages, and administration methods suitable for particular indications, like metabolic disorders or inflammatory diseases.
The claims delineate both composition-based and method-based inventions:
- Composition claims specify the combination of active ingredients in fixed or variable ratios.
- Method claims describe methods of administering the composition for treatment purposes.
The scope also extends to specific formulations, such as controlled-release forms, and to diagnostic or predictive uses based on biomarkers present in the patient population.
What Are the Specific Claims?
The patent contains 10 independent claims and approximately 15 dependent claims. The core claims focus on:
- A pharmaceutical composition containing a first active agent (e.g., a known therapeutic compound) and a second agent (e.g., an adjuvant or modulator).
- The ratios of active ingredients, typically within a specified range (e.g., 1:1 to 1:10).
- Methods of administering the composition to treat or prevent diseases, including dosage regimens.
Sample independent claims:
-
A pharmaceutical composition comprising:
- Compound A at a dose of 10–50 mg per unit dose; and
- Compound B at a dose of 20–100 mg per unit dose;
wherein the composition is formulated for oral administration.
-
A method for treating inflammation in a patient, comprising administering the composition of claim 1.
Dependent claims specify variations such as:
- Using a specific salt form of the active ingredients.
- Adjusting formulation parameters for sustained release.
- Applying the method to specific disease indications, including rheumatoid arthritis or diabetes.
Claims are supported by experimental data demonstrating improved efficacy over separate administration of components, with particular emphasis on synergistic effects and reduced side effects.
