Company patents

KOREA ZINC CO., LTD.

KOREA ZINC CO., LTD. shows a surprising shift in its patent strategy, with significant declines in its core areas: Batteries & Fuel Cells, which constitutes 32.4% of its portfolio, saw a 77.8% YoY drop in 2025 and a further 50.0% decline so far in 2026, while Compounds Containing Metals (27.0% of portfolio) also experienced a 50.0% YoY decrease in 2025 and a 66.7% decline in 2026. This suggests a potential re-evaluation of priorities, especially given the emergence of new, albeit small, interests in Image Processing and Computer Vision, each with 1 patent so far in 2026.
