Claims Overview
The claims define the legal breadth of the patent, and for EP2343071, they are structured as follows:
Independent Claims
-
Diagnostic Method Claim
A method for diagnosing or predicting a cardiovascular disease in a subject, comprising measuring at least one specified biomarker within a biological sample (e.g., blood, plasma, serum) and comparing the result to a predetermined threshold indicative of disease presence or risk.
-
Biomarker Combination Claim
Use of a specific combination of biomarkers (e.g., biomarkers A, B, and C) for enhanced diagnostic accuracy or prognosis prediction in cardiovascular diseases.
-
Prognostic Method Claim
A method for determining the prognosis of a cardiovascular disease by quantifying biomarker levels and correlating them with disease progression markers.
Dependent Claims
Dependent claims specify particular aspects, such as:
- Specific biomarker compositions (e.g., particular proteins or nucleic acid markers).
- Methods involving particular detection technologies (e.g., ELISA, PCR).
- Threshold values or cutoff ranges for biomarkers.
- Specific disease conditions (e.g., heart failure, myocardial infarction).
This layered claim structure ensures broad coverage while enabling narrower, more enforceable claims related to specific methodologies or biomarker sets.
Patent Landscape and Strategic Positioning
