Company patents

KEIO UNIVERSITY

KEIO UNIVERSITY's patent strategy reveals a surprising shift away from core pharmaceutical areas, with 'Peptides & Proteins' experiencing a significant decline of 100% in 2026 so far, after a 50% drop in 2025. While 'Medical Diagnostics & Surgery' showed strong growth of 100% in 2024, its overall portfolio share remains modest at 12.1%, suggesting a diversified but potentially less concentrated focus on emerging medical device innovations compared to its traditional pharma strengths.
