Company patents

Kowa Company, Ltd.

Kowa Company, Ltd. exhibits a strong and resurging focus on pharmaceutical innovation, with 'Pharmaceutical Preparations' representing 40.0% of its portfolio and showing a significant 125.0% growth so far in 2026, alongside 'Therapeutic Activity (Pharma)' which grew 50.0% in 2026, indicating a strategic pivot back to core pharma after a dip in 2025. Surprisingly, despite a previous surge, the company's patent activity in 'Animal Husbandry / Fishing' has completely ceased so far in 2026, declining by 100.0% YoY, suggesting a shifting priority away from this sector.
