Claims Analysis
1. Independent Claims
The patent primarily comprises three independent claims, which collectively define the breadth of protection:
-
Claim 1: A method for predicting a patient’s response to a therapeutic agent comprising:
- obtaining a biological sample from the patient;
- measuring the expression levels of a specified set of biomarker genes;
- comparing the gene expression profile to a reference signature;
- classifying the patient as likely responders or non-responders based on the comparison.
-
Claim 2: A diagnostic panel comprising primers or probes specific to the biomarker genes identified in Claim 1, for use in predicting the therapeutic response.
-
Claim 3: A computer-implemented method involving algorithms that analyze gene expression data to classify patient response.
2. Dependent Claims
Dependent claims specify particular biomarkers, algorithms, and methods of analysis, including:
- Use of specific gene signatures validated in clinical cohorts.
- Application to certain pharmacological classes (e.g., oncology therapeutics).
- Details regarding sample types (e.g., blood, tissue biopsies).
- Algorithmic thresholds and validation parameters.
Scope of Claims
The claims emphasize personalized medicine through molecular diagnostics, secured by both methodological steps and tangible diagnostic tools. The focus is on gene expression-based predictions, which are well-established yet tailored here through specific signatures and algorithms.
