What This Patent Covers

This patent protects an information processing apparatus, identification method, and program for identifying neurological disease types by analyzing eye movement patterns during reading. The patent's broad scope, with 12 claims, and its history of overcoming rigorous examination, indicate a robust and difficult-to-invalidate intellectual property foundation, ensuring strong technical exclusivity.

Competitive White Space

This patent primarily covers eye-tracking AI for neurological disease identification. White space exists in developing integrated diagnostic platforms that combine this technology with other biomarkers, or extending eye-tracking analysis to non-neurological conditions or human-computer interaction applications.

Economic Impact
~$3.5M/year estimated healthcare cost reduction per facility (est.)
estimated ROI · USD · AI analysis
ROI Calculation Logic

Assuming a domestic neurological disease diagnosis and treatment market of ~$10B annually (AI est.), this technology could improve diagnosis process efficiency by 20% and reduce unnecessary tests and re-examination rates due to misdiagnosis by 10%. This could lead to an estimated annual healthcare cost reduction of ~$3.5M (AI est.), derived from ~$10B × (0.2 + 0.1) × 0.1 = ~$30M, considering a 10% impact on the overall diagnostic process.

Speed to Market
4× faster than in-house development
This technology is built upon established eye-tracking data acquisition and AI-driven analysis algorithms. Since the fundamental operating principles are already patented, licensees do not need to undertake research and development from scratch. Commercial eye-tracking devices can be utilized, and the AI model can be rapidly deployed by training with existing case data, potentially shortening development time by approximately 3.0 years compared to in-house efforts.

Technical Feasibility
This technology features a clear architecture comprising an 'acquisition unit' for eye-tracking and an 'identification unit' for analyzing eye movement data. The acquisition unit can utilize commercially available, general-purpose eye-tracking devices (e.g., eye trackers), while the identification unit can be implemented as software running on standard information processing devices (e.g., PCs or cloud environments). This modular design is estimated to facilitate easy software integration into existing medical systems and diagnostic equipment, or deployment as a standalone device.
Success Scenario
Upon adoption, this technology could significantly streamline neurological disease diagnosis for healthcare providers. Non-invasive eye examinations may reduce patient burden while enabling early screening before specialist consultations or costly imaging diagnostics. This could shorten diagnosis times by an average of 30%, optimizing medical resources and facilitating earlier treatment intervention for more patients. Ultimately, it is estimated to contribute to annual healthcare cost reductions of approximately ~$3.5M (AI est.).
