Scope of Patent FI3628319
Scope Overview
FI3628319 focuses on the detection and prognostic assessment of autoimmune diseases through a specific biomarker signature. The patent covers a diagnostic method that involves analyzing particular molecular markers, such as gene expression profiles, autoantibody levels, or specific cytokine patterns, to determine the presence or anticipatory risk of autoimmune disorders like rheumatoid arthritis, systemic lupus erythematosus, or multiple sclerosis.
Scope Boundaries
- The claimed methods encompass both laboratory-based assays and computational algorithms for interpreting biomarker data.
- The patent delineates its scope around sample types (e.g., blood, serum, plasma), analytical techniques (e.g., PCR, ELISA, mass spectrometry), and data analysis methods (e.g., machine learning models).
- It emphasizes prognostic and diagnostic applications, potentially extending to personalized medicine approaches and early intervention strategies.
Geographical and Legal Scope
- As a Finnish patent, the protection is enforceable within Finland, but due to the European Patent Convention (EPC) framework, similar claims could be extended via filing at the European Patent Office (EPO) or national filings, subject to jurisdictional validations.
- The patent's claims also describe a methodology that could be adaptable or patentable in other jurisdictions, contingent on local laws and prior art considerations.
