What This Patent Covers

This patent protects a two-stage machine learning method for disease severity prediction, covering a broad technical scope with 10 claims. Its stability is reinforced by successfully overcoming examiner rejections against four prior art documents, demonstrating clear differentiation from existing technologies.

Competitive White Space

This patent focuses on the core prediction algorithm. White space exists in integrating this model with specific medical devices, developing patient-facing mobile applications, or creating specialized predictive models for rare diseases not covered by the initial training data.

Economic Impact
~$1.5M/year estimated medical cost reduction per facility (est.)
estimated ROI · USD · AI analysis
ROI Calculation Logic

By enabling early prediction of disease severity, this technology could shorten unnecessary hospital stays and avoid high-cost treatments. For example, assuming an average medical cost reduction of ~$150 per patient for 10,000 patients annually, an estimated annual saving of ~$1.5M (10,000 patients × ~$150) could be achieved.

Speed to Market
4× faster than in-house development
This technology is based on a patented, established algorithm. Licensees can significantly shorten development time and time-to-market by approximately 2.2 years, avoiding the need for ground-up R&D.

💊 New Drug Development & Clinical Trials
Clinical Trial Participant Selection Support
This system could be repurposed to efficiently select patient groups with specific symptoms or severity risks for new drug clinical trials. This is expected to shorten trial periods, improve success rates, and reduce development costs, contributing to more effective pharmaceutical development.
🤖 Smart Cities & Community Monitoring
Community Health Risk Surveillance
This technology could be applied to predict disease severity risk across an entire community, utilizing resident health data and regional medical information held by local governments. This could enable early intervention in medically underserved areas, efficient allocation of medical resources, and optimization of health promotion initiatives.
Integration Roadmap — Estimated 18-Month Deployment
Phase 1: Technology Evaluation & Requirements Definition
Duration: 3 months
Evaluate the detailed algorithm and define integration requirements with the licensee's existing systems and data infrastructure. Specify target diseases and prediction objectives.
Phase 2: Model Development & System Integration
Duration: 9 months
Build the secondary learning model using acquired patient data and integrate the prediction engine via API linkage with existing EHR and lab systems. Conduct prototype validation.
Phase 3: Pilot & Operational Launch
Duration: 6 months
Conduct pilot operations in a limited environment to finalize prediction accuracy and system stability. Incorporate feedback from medical professionals and initiate full-scale operation.
Technical Feasibility
This technology, a learning model generation method using patient information as explanatory variables and severity as the objective variable, has high compatibility with data from existing medical information systems (e.g., electronic health records, lab data, questionnaires). Primarily implemented as software, it requires no significant physical infrastructure investment. Integration into existing IT infrastructure through system linkage and algorithm embedding could enable relatively easy adoption.
Success Scenario
Upon adoption, healthcare professionals could access real-time AI-driven severity prediction scores during patient consultations. This could accelerate early intervention and the development of appropriate treatment plans, potentially reducing average patient hospitalization by an estimated 15%. Furthermore, the medical cost containment achieved through severity prevention could reach hundreds of millions of dollars annually, significantly contributing to efficient healthcare management.
