Company patents
DENSO WAVE INCORPORATED
DENSO WAVE INCORPORATED shows a surprising shift in its patent strategy, with a significant decline in its traditionally strong areas like Data Recognition (Barcodes, OCR), which saw an 83.3% drop in 2026 so far, and Manipulators & Robotics, down 40.0% in 2026 so far, despite these categories each representing 20.8% of its total portfolio. This suggests a potential re-evaluation of core technological investments, with a notable, albeit volatile, emerging focus in Industrial Control Systems, which experienced a 300.0% growth in 2025 before a 75.0% decline in 2026 so far, indicating an exploratory rather than sustained investment in this area.
