Company patents

Max Co., Ltd.

Max Co., Ltd.'s patent strategy reveals a surprising shift away from its core manufacturing categories, with both "Packaging Machines" (27.5% of portfolio) and "Hand Tools" (18.7% of portfolio) experiencing significant declines in 2025 (YoY -64.7% and -40.9% respectively) and continuing into 2026. While "Horticulture & Forestry" shows consistent activity with 3 patents so far in 2026, the sharp drop in patenting for "Motor Control" and "Electric Motors & Generators" (both -100.0% YoY in 2026) suggests a shifting priority in electrical power technologies.
