Overview of Patent AU2016262185
Filed on December 22, 2016, by The University of Queensland, the patent was granted in Australia and published under application number AU2016262185A1. Its core innovation resides in a diagnostic method that employs specific biomarkers or molecular signatures to identify or monitor MS.
The claims comprise methods that involve detecting particular biomolecules—likely proteins, RNAs, or metabolites—in biological samples (e.g., blood, cerebrospinal fluid). The overarching aim is improved accuracy and early diagnosis, emphasizing molecular diagnostics over traditional imaging or clinical assessments.
Scope of the Patent
1. Technical Focus
The patent's scope emphasizes diagnostic methods for MS based on detecting one or more biomarkers indicative of the disease state. Specifically, the invention involves:
- Biomarker detection techniques: using assays or molecular detection platforms to measure biomolecule levels.
