Company patents
HORIBA STEC, Co., Ltd.
HORIBA STEC CO., LTD. demonstrates a strong and consistent focus on core manufacturing technologies, with Industrial & Autonomous Control representing 35.2% of its portfolio and Flow / Volume Measurement and Valves each accounting for 26.2%. While patenting in Semiconductor Manufacturing Process saw a significant surge of +125.0% in 2025, it's surprising to note a complete absence of new patents in this area so far in 2026, alongside a -100.0% decline in Machine Learning & AI patents from 2023 to 2024, indicating a potential shift away from these advanced computing applications.
