Company patents
Microjet Technology Co., Ltd.
Microjet Technology Co., Ltd. demonstrates a surprising shift in its patent strategy, moving away from its historical focus on "Pumps (Positive Displacement)" and "Valves," which saw a 100% decline in patenting activity in 2025 and 2026 so far, despite these categories representing 14.9% and 5.3% of its total portfolio, respectively. Instead, the company is rapidly emerging in "Sterilization & Biocompatible Materials," which experienced a remarkable 250.0% year-over-year growth in 2025, indicating a strategic pivot towards medical device technologies.
