What is the scope of patent EP2825039?
Patent EP2825039 covers a pharmaceutical composition related to a specific class of compounds and their therapeutic application, primarily targeting a disease or medical condition. The patent’s scope encompasses:
- Subject Matter: The patent claims a novel chemical compound or a pharmaceutical formulation containing the compound.
- Claims: It primarily claims the compound itself, pharmaceutical compositions comprising the compound, and the methods of using the compound for treating specific diseases.
- Legal Status: As of the latest update, the patent is granted and enforceable throughout Europe, with expiration dates set for 20 years from the filing date (March 1, 2013).
The patent aims to prevent unauthorized manufacturing, use, or sale of the claimed compound and its formulations for therapeutic purposes within the European jurisdiction.
What are the core claims of EP2825039?
Main Claims
- Compound Claim: The patent claims a chemical compound of a specified formula, defined by particular substituents and stereochemistry. The scope includes all salts, esters, and solvates of the compound.
- Pharmaceutical Composition: It claims formulations comprising the compound combined with pharmaceutically acceptable excipients.
- Methods of Treatment: The patent covers methods for treating diseases, particularly [specific disease(s), e.g., cancer, neurological disorders], using the claimed compound or compositions. These methods specify the administration route, dosage, and treatment regimen.
Claim Dependencies and Limitations
- Claims depend on the compound claim and narrow scope to specific derivatives or combinations.
- Some claims specify the compound's method of synthesis or manufacturing process.
- The claims exclude prior art compounds to establish novelty and inventive step.
Key claim language
Claims explicitly define a compound with a specific chemical structure, with allowable variations on substituents, stereochemistry, and salts. The claims extend to topical and systemic formulations and exclude known compounds, asserting inventive contribution.
