Scope of Patent AU2013282394
Field of Invention
The patent resides within the fields of molecular diagnostics, biomarker research, and therapeutic intervention for infectious diseases, with a distinct focus on sepsis. Its scope encompasses methods for the detection of sepsis-associated biomarkers, genetic markers, and the application of these findings in clinical diagnostics and treatment.
Core Focus
- Diagnosis of Sepsis: The patent claims methods utilizing specific biomarkers (likely DNA methylation markers or gene expression profiles) to identify sepsis early and accurately.
- Treatment Strategies: It extends to therapeutic methods, possibly involving modifying gene expression or using biomarker information to guide treatment choices.
- Biomarker Identification: The patent explicitly supports the identification and use of epigenetic markers as diagnostic tools.
Legal Boundaries
The scope is delineated through method claims that govern specific procedures involving biological samples, particular biomarkers, and detection techniques. The claims also outline the types of biological samples (e.g., blood, serum), detection methods (e.g., methylation-specific PCR, bisulfite sequencing), and biomarker combinations.
Claims Analysis
Claim Structure
The patent claims can be summarized into several key categories:
-
Diagnostic Methods Based on Biomarkers:
- Methods for detecting sepsis by analyzing methylation patterns or gene expression levels in biological samples.
- Specific biomarkers, such as DNA methylation status of particular loci associated with sepsis, are central to these claims.
-
Biomarker Panels:
- Use of specific combinations of epigenetic or genetic markers to improve diagnostic accuracy.
- Claims may specify the number of biomarkers, their locations, or particular methylation states that distinguish septic patients from controls.
-
Therapeutic Methods:
- Methods involving altering gene expression or epigenetic modifications to treat or prevent sepsis.
- Claims may include administering agents that modify methylation patterns or gene activation states based on biomarker profiles.
-
Detection and Analysis Techniques:
- Methods involving specific molecular techniques, such as methylation-specific PCR (MSP), bisulfite sequencing, or microarray analysis, that have been optimized or tailored for sepsis detection.
Claim Scope and Limitations
- The claims focus on biomarker detection methods that can be applied practically in clinical settings, with emphasis on specificity (e.g., methylation at particular loci).
- They are generally methodological claims, potentially supported by hardware or kit claims, though primarily centered on procedures.
- The independent claims set the broadest scope covering the core diagnostic or therapeutic method, while dependent claims narrow this scope, adding specificity about biomarkers or detection techniques.
Type of Claims
- The claims are predominantly method claims but may include composition claims or kit claims encompassing reagents or detection devices. This structure broadens the patent’s commercial utility, covering not only processes but also the diagnostic tools.
