Company patents
DAIWA CAN COMPANY
DAIWA CAN COMPANY's patent strategy, while heavily focused on its core "Containers & Packaging" (53.2% of portfolio), shows a surprising emerging interest in "Batteries & Fuel Cells," which saw a 100.0% year-over-year growth in 2026 (so far), indicating a potential diversification beyond traditional packaging. Conversely, categories like "Layered Products (Laminates, Films)" and "Spraying & Atomizing" have seen significant declines, with 2026 (so far) showing -100.0% YoY decreases, suggesting a shifting priority away from these areas.
