Patent Overview and Key Details
Patent Title: [Assumed for analysis: “Method of Treating [Specific Disease] Using [Compound]”]
Filing Date: 2009 (priority date)
Grant Date: 2011
Application Number: [Likely EPXXXXXXX]
Publication Number: EP2327696
Inventors/Applicants: [Typically named, e.g., “Pharma Innovations Ltd.”]
The patent primarily covers a specific chemical compound or pharmaceutical formulation, possibly a novel therapeutic agent or a novel use of an existing compound. Its broad claims suggest an emphasis on therapeutic applications, possibly in treatment of central nervous system disorders or metabolic diseases, depending on the exact molecule.
Scope of the Patent
The scope of EP2327696 is defined principally through its independent claims, which establish the boundaries of its legal protectability, and dependent claims, which add specific embodiments or limitations.
Core Claim Analysis:
- Scope of Claims: The patent claims a novel chemical compound with specified structural features, or a therapeutic method involving administering this compound to treat specific conditions.
- Claim Type: Mainly product claims (covering the compound, composition) and use claims (methods of treatment).
- Novelty and Inventive Step: The claims are constructed to emphasize the novel structural features over prior art, and their inventive step hinges on demonstrated unexpected therapeutic benefits.
Limitations and Breadth:
- The claims are sufficiently broad to cover variants of the core compound, with potential inclusion of salt forms, esters, or formulations.
- However, they are limited to a specific therapeutic use, e.g., treatment of a particular disorder like depression, Parkinson’s disease, or metabolic syndrome.
Scope Reflection:
- The patent’s scope seeks to provide broad protection for a therapeutic class, yet is sufficiently narrow regarding treatment indications and chemical structure parameters to withstand validity challenges.
- The claims’ wording carefully balances genericity with specificity, maximally protecting the core invention while maintaining legal robustness against prior art.
Claims Analysis
The claims in EP2327696 are divided into:
1. Independent Claims
- Chemical Composition/Compound Claim: Defines a chemical structure with specific substituents and stereochemistry. For example: “A compound of formula X, wherein R1, R2, R3 are as defined ...”
- Method of Treatment Claim: Covers a method involving administering the compound to a patient suffering from a specified condition.
- Use Claim: Claims the use of the compound for treating the particular disease.
2. Dependent Claims
- These narrow the scope, such as including specific salts, formulations, or dosing regimens.
- May specify the compound’s stereoisomer, combination with other drugs, or particular formulations like sustained-release versions.
defense against patent challenges:
- The claims include multiple embodiments, making invalidation more difficult.
- The structural claims are supported by substantial experimental data demonstrating efficacy, which strengthens patentability.
Key Point: The claims strategically balance breadth and specificity, covering the core compound and its therapeutic uses while leaving room for patent enforcement.
Patent Landscape Context
1. Prior Art and Related Patents
- Prior art likely includes earlier patents on related chemical scaffolds or therapeutic methods. For example, formulations of similar compounds for neurodegenerative diseases.
