Company patents
MAYEKAWA MFG. CO., LTD.
MAYEKAWA MFG. CO., LTD. shows a surprising shift in its patent strategy, with a strong focus on manufacturing technologies, as evidenced by the emergence of 'Pumps (Positive Displacement)' with 6 patents in 2025 (9.5% of its portfolio) from zero in prior years, and 'Manipulators & Robotics' experiencing a 200.0% YoY growth in 2024. While traditionally strong in 'Refrigerators & Cold Storage' and 'Refrigeration' (each 12.7% of portfolio), the complete absence of new patents across nearly all categories so far in 2026 suggests a potential re-evaluation or a significant slowdown in new filings compared to previous years.
