IP Defensibility — Why Competitors Can't Replicate This
What This Patent Covers

This patent protects a diagnostic support system utilizing EEG time-series data for frequency analysis and multi-faceted feature extraction, including spatio-temporal correlation coefficients, to differentiate acute encephalopathy. It was granted after successfully overcoming an office action with precise arguments and amendments, indicating a robust and stable scope with low invalidation risk.

Competitive White Space

This patent primarily covers EEG-based diagnostic support. White space exists in integrating this AI with other biosignal analysis (e.g., EMG, EKG), developing therapeutic interventions based on early diagnosis, or expanding into non-neurological diagnostic applications.

ROI Calculation Logic

Early diagnosis of status epilepticus-type acute encephalopathy could reduce the risk of sequelae, thereby curbing healthcare costs associated with long-term hospitalization and rehabilitation. For example, assuming 300 patients annually incur an additional ~$33.5K (AI est.) in medical expenses due to sequelae from delayed diagnosis, this technology's early diagnosis could avert 10% of these costs, leading to an estimated annual healthcare saving of ~$1.0M (300 patients × ~$33.5K × 10%) (AI est.).

Speed to Market
4× faster than in-house development
This technology's core components are EEG data acquisition and analysis algorithms, which can be integrated relatively easily with existing EEG measurement devices. As a result of university research, the foundational algorithms are already established, and the proof-of-concept stage is presumed complete. This could shorten development time by approximately 3 years compared to a company developing similar technology from scratch, enabling faster market entry and competitive advantage.
