Company patents
PFU LIMITED
PFU LIMITED's patent strategy reveals a surprising shift away from its dominant Material Handling (Sheets, Webs) category, which constitutes 56.7% of its portfolio but saw a 43.3% decline in 2025 and a further 35.3% decline so far in 2026. Concurrently, the company is rapidly expanding its focus on Computer Vision and Image Processing, with Computer Vision experiencing a 150.0% growth so far in 2026 and Image Processing surging by 300.0% in the same period, indicating an emerging emphasis on advanced computing technologies.

Mechanisms and sensors for accurately conveying, positioning, loading, and managing various types of recording media (e.g., paper, fabric, labels) through a printing apparatus, and detecting their presence, type, or potential collision.
Mechanisms and control systems for reliably feeding, conveying, and separating print media, including managing media roll changes, adjusting airflow, and adapting to different media characteristics.
Technologies for maintaining the correct path and alignment of webs or individual sheets during conveyance, including mechanisms for steering, correcting positional deviations, and managing static electricity.
Systems that employ imaging and image processing to automatically detect defects, verify states, or ensure quality control in manufactured goods, printed materials, or industrial processes.
Systems that perform operations like cutting, folding, binding, or applying liquids to sheets or webs, often integrated within larger production lines such as printing or image forming apparatuses.
Apparatus and methods for automatically winding or unwinding continuous materials such as webs, cables, conduits, or yarns onto or from spools, reels, or bobbins, including aspects like layering, coreless winding, and material supply.
Methods and apparatus for improving the visual fidelity, resolution, or compression efficiency of video signals, often through advanced processing, up-scaling, or neural network-based filters.
Methods and systems for uniquely identifying individual units of material (e.g., yarn spindles, winding spools, bobbins) and monitoring their performance or status within a material handling process, often using sensors and coding.
Technologies for precisely controlling the timing and volume of liquid droplet ejection, and for real-time or post-ejection monitoring of droplet trajectory, velocity, and nozzle health to maintain print accuracy and quality.
Systems and methods for precisely measuring, monitoring, and regulating the longitudinal tension in continuous webs of material during roll-to-roll processes to prevent defects, reduce waste, and ensure consistent product quality.
Systems that combine data from multiple camera sensors or capture multiple images from different perspectives or qualities, often involving image processing techniques like synthesis to create enhanced or comprehensive views.
