Patent Overview and Filing Details
- Filing Date: July 12, 2018
- Publication Date: February 15, 2020
- Inventors: Dr. María López and colleagues
- Applicants: PharmaInnovations S.L.
- Patent Number: ES2439581
The patent claims a pharmaceutical composition primarily comprising a specific combination of active ingredients aimed at treating inflammatory conditions, with emphasis on enhanced bioavailability and reduced side effects.
Scope of the Patent
The scope of ES2439581 is centered on the composition and method of use for treating inflammatory diseases, including conditions such as rheumatoid arthritis, inflammatory bowel disease, and psoriasis. The scope extends to:
- Formulations: Specific combinations of active pharmaceutical ingredients (APIs), including a novel anti-inflammatory agent coupled with bioavailability enhancers.
- Methodology: Use of the formulation for reducing inflammation and associated symptoms.
- Manufacturing processes: Techniques for preparing the composition to optimize stability and absorption.
The core innovation lies in the synergistic combination that purportedly achieves superior therapeutic outcomes or reduced adverse effects compared to existing formulations.
Claim Analysis
Independent Claims
The patent features one primary independent claim, which can be summarized as:
“A pharmaceutical composition comprising at least one anti-inflammatory agent selected from [list of specific APIs] and a bioavailability enhancer selected from [specific excipients or formulations], wherein the composition exhibits improved bioavailability and efficacy in the treatment of inflammatory disorders.”
Key aspects of this claim:
- Component specificity: It narrows down to particular API combinations.
- Functional enhancement: Emphasizes improved bioavailability and efficacy.
- Application: Targets treatment of inflammatory conditions.
Dependent Claims
Dependent claims elaborate on specific embodiments, including:
- Variations in the ratio of APIs.
- Specific excipients or stabilizers used in the composition.
- Methods of administering the composition, such as oral, topical, or injectable forms.
- Storage conditions and stability parameters.
Claim Breadth and Protectability
The focus on particular API combinations and formulation techniques constrains the claims, indicating a moderate scope intended to prevent easy workaround but not overly broad to risk invalidation. The emphasis on improved bioavailability and efficacy aligns with patentability requirements of novelty and inventive step.
Patent Landscape and Competitor Overview
Key Related Patents and Applications
