2. Detailed Scope and Claims Analysis
2.1. Claim Structure and Core Innovations
The patent encompasses 16 claims, categorized into independent and dependent claims, establishing both foundational and specific embodiments of the technology.
2.1.1. Independent Claims
-
Claim 1:
Defines a method of diagnosing a disease comprising steps of obtaining a biological sample, analyzing it for a specific panel of biomarkers, and interpreting the data using a computational model to assess disease risk or progression.
-
Claim 9:
Focuses on a therapeutic method where identified biomarkers guide personalized treatment selection, combining diagnostic results with tailored pharmaceutical or therapeutic interventions.
These claims establish the core inventive concept: integrating biomarker analysis with computational data interpretation to aid in diagnosis and treatment.
2.1.2. Dependent Claims
Dependent claims expand on specific embodiments, such as:
- Use of specific biomarker panels (e.g., genetic mutations, protein expression profiles).
