Company patents
Fujikura Ltd.
Fujikura Ltd.'s patent strategy reveals a surprising shift away from its dominant "Optical Elements & Systems" category, which, despite comprising 54.0% of its portfolio, saw a significant 56.8% decline in patenting activity so far in 2026. Concurrently, the company is showing an emerging focus on "Machine Learning & AI," with a remarkable 200.0% year-over-year growth in 2026, and a notable, albeit volatile, interest in "Impedance Networks (Filters, Resonators)" which experienced a 550.0% surge in 2024 before a subsequent decline, suggesting a dynamic re-evaluation of its core and emerging technology investments.
