Company patents

HANWHA TECHWIN CO., LTD.

HANWHA TECHWIN CO., LTD. shows a surprising and drastic shift in its patent strategy, with significant declines across nearly all categories since 2023. For instance, 'Pictorial / Video Communications,' its largest category at 43.1% of its portfolio, saw a -90.9% YoY drop in 2024, while 'Computer Vision' and 'Image Processing' experienced -93.8% and -100.0% YoY declines respectively in the same year, indicating a broad de-emphasis on these core areas, with only minor recoveries in 2025 and continued declines so far in 2026.
