This patent provides critical insights into its scope, claims, and positioning within the broader patent landscape. Understanding these elements enables stakeholders in pharmaceutical R&D, licensing, and patent strategy to gauge the patent's strength, potential infringements, and competitive landscape.
Patent Overview and Technical Field
EP2570128 addresses inventions related to specific chemical entities, their formulations, and methods of use, primarily targeting indications such as neurological disorders, metabolic diseases, or cancers—common therapeutic areas for innovative drugs. The patent emphasizes a particular class of compounds, possibly with novel substitutions or modifications, designed to improve efficacy, bioavailability, or safety profiles over existing therapies.
Scope of the Patent
Scope Definition
The scope of EP2570128 encompasses:
- Chemical compounds, characterized by a core structure with specified substituents or stereochemistry.
- Pharmaceutical formulations incorporating the claimed compounds.
- Methods of treatment, explicitly claiming therapeutic methods involving the administration of these compounds for particular indications.
The patent's scope hinges on the breadth of its claims, which are designed to cover:
- Chemical variants within a certain structural class.
- Uses in treating specific diseases.
- Formulation specifics—e.g., dosage forms, excipients, or delivery methods.
Limitations and Boundaries

- Structural parameters: Definitions of substituents, stereochemistry, and core frameworks.
- Therapeutic indications: Use claims linked to particular diseases or physiological targets.
- Formulation limitations: Specific preparation methods or carriers.
Claim scope is balanced to be broad enough to prevent easy workarounds but specific enough to avoid being invalidated for lack of novelty or inventive step.
Claim Analysis
Claims Breakdown
-
Independent Claims: Usually define the core inventive compounds and their uses.
-
Dependent Claims: Narrow down the scope, providing specific embodiments, such as particular substituents, stereoisomers, or formulations.
Key Elements
- Compound claims typically describe structural formulae, such as a six-membered aromatic ring with particular substituents.
- Use claims specify methods of treatment involving administering the compound to a patient experiencing a disease state.
- Formulation claims detail compositions including the inventive compound alongside excipients or delivery mechanisms.
Novelty & Inventive Step
The claims hinge on novel structural features not disclosed in prior art, coupled with demonstrated unexpected therapeutic benefits. The inventive step is often supported by data showing superior efficacy, reduced side effects, or enhanced pharmacokinetics—distinguishing the claims from prior art.
Potential Claim Breadth
