What This Patent Covers

This patent establishes a clear technical scope for a Progressive Supranuclear Palsy (PSP) diagnostic marker, specifically the detection of a particular peptide fragment in cerebrospinal fluid. The patent's robustness and validity are demonstrated by its successful navigation through the examination process, overcoming an initial rejection with precise amendments and arguments, indicating a low invalidation risk and strong competitive advantage.

Competitive White Space

This patent primarily covers CSF-based peptide fragment detection for PSP diagnosis. White space exists for developing diagnostic biomarkers for other neurodegenerative diseases using alternative sample types or different molecular classes, and for therapeutic applications targeting the identified pathways.

ROI Calculation Logic

Considering increased medical costs and reduced patient QOL due to delayed PSP diagnosis. Assuming an average current diagnostic process cost of ~$3,350/person (AI est.) (imaging, multiple consultations) for ~1,000 new domestic patients annually. If this technology shortens diagnosis by an average of 6 months and reduces related costs by 20%, direct annual savings could reach ~$650K (AI est.). Additionally, early diagnosis and appropriate treatment could reduce indirect costs, such as long-term care and social reintegration support, by over ~$650K annually (AI est.).

Speed to Market
5× faster than in-house development
This technology has achieved patent approval as a research outcome from Tottori University, indicating that fundamental R&D is complete.
