Introduction
European Patent Office (EPO) patent EP3134061, titled "Methods for detecting and monitoring disease states and conditions," has garnered substantial attention within the pharmaceutical and biotechnology sectors. As an influential patent, understanding its scope, claim architecture, and positioning within the patent landscape is vital for stakeholders conducting due diligence, strategic planning, or competitive intelligence.
This article rigorously dissects the scope of EP3134061, elucidates its claims, and situates it within the broader patent environment, emphasizing its relevance in biomarker detection and disease management technologies.
1. Overview of Patent EP3134061
EP3134061 was granted in 2017 and assigned primarily to a biotech innovator focused on diagnostic methodologies. The patent encompasses foundational techniques for identifying and monitoring disease states through biomarker analysis, especially via minimally invasive methods such as liquid biopsies.
The patent claims to innovations in detecting specific protein or nucleic acid markers, offering potential applications in oncology, infectious diseases, and other chronic conditions.
2. Scope of EP3134061
2.1 Core Focus
The patent is centered on diagnostic methods grounded in analyzing biological samples—such as blood, plasma, or serum—to identify biomarkers indicative of disease presence, progression, or response to therapy. Its scope is primarily clinical and laboratory methods, though it extends to related apparatus configurations.
2.2 Biological Markers and Targets
While the patent broadly covers the detection of any disease-related biomarker, it emphasizes circulating nucleic acids (cfDNA, miRNA), proteins, or exosomes. This wide coverage intersects with modern biomarker discovery, emphasizing non-invasive diagnostics.
2.3 Sample Processing Techniques
The patent details novel sample processing and analytical techniques that improve sensitivity and specificity, including enrichment processes, amplification steps, and device integration. These techniques aim to detect low-abundance biomarkers reliably.
2.4 Disease Applications
Although the invention applies broadly to disease detection, oncology (particularly liquid biopsy-based detection of mutational profiles in tumors) serves as the primary use case. The scope extends to infectious diseases and chronic conditions, with adaptations in biomarker types.
3. Analysis of Claims
3.1 Claim Structure
EP3134061 contains a set of independent claims that define the inventive core, complemented by numerous dependent claims elaborating specific embodiments, methods, or apparatus features.
3.2 Independent Claims
The main independent claims are structured to encompass:
