Company patents
DANA CANADA CORPORATION
DANA CANADA CORPORATION's patent strategy reveals a surprising shift away from its core focus areas, with significant declines across its top categories. While 'Heat Exchange Components' (42.9% of portfolio) and 'Batteries & Fuel Cells' (31.0% of portfolio) were prominent, both saw a -100.0% decline in patenting activity so far in 2026, indicating a potential reprioritization, despite 'Batteries & Fuel Cells' experiencing a +50.0% growth in 2024.
