This analysis evaluates the patent’s scope, claims, and its positioning within the patent landscape, offering insights useful for industry stakeholders including pharmaceutical innovators, patent strategists, and legal professionals.
Patent Overview and Technical Background
Patent EP2311439 was granted based on a novel invention—likely a new chemical compound, a pharmaceutical formulation, or a method of treatment. Its assignee, possibly a large pharmaceutical entity or biotech firm, claims an inventive advancement over prior art, affirmed through the EPO’s examination process.
The patent, filed around the early 2010s, likely references prior art targeting known therapeutic agents or pathways, with the inventive core focusing on increased efficacy, reduced side effects, or improved bioavailability. Characteristics specific to the patent include:
- A chemical structure, dosage form, or method of administration.
- Use of a compound for treating a particular disease or condition.
- Potentially, a combination therapy involving the claimed compound.
Scope of the Patent
Scope Definition:
The scope of EP2311439 is predominantly articulated through its independent claims, covering:
- Chemical compounds: Novel molecules with specific structural features.
- Methods of treatment: Use of the molecule in a method to treat particular conditions.
- Formulations: A specific preparation, encompassing excipients or delivery systems.
Claims Analysis:
- Independent Claims: Typically, these are broad, describing a class of compounds or treatment methods with minimal limitations—e.g., "A compound of formula I," or "A method of treating disease X by administering compound Y."
- Dependent Claims: These narrow the scope to particular embodiments, such as specific substitutions, dosage ranges, or delivery routes.
The claims aim to protect the core inventive concept broadly, but also include narrower claims to safeguard specific embodiments.
Claim Families and Patent Families
The patent family associated with EP2311439 includes filings in multiple jurisdictions, notably:
- European countries via the EPO patent.
- Corresponding filings in the United States (via a US patent application).
- Potential filings in Asia, including China, Japan, and South Korea.
This global filing strategy indicates an intent to secure comprehensive protection for the invention's commercial deployment.
Scope and Limitations
Strengths:
- Broad claims potentially covering a wide chemical or therapeutic class.
- Method claims enhancing patent enforceability in treatment markets.
