Company patents
Nidec Motor Corporation
Nidec Motor Corporation's patent strategy shows a surprising decline in its core 'Electric Motors & Generators' category, which still represents 56.2% of its portfolio but has seen a significant -29.4% YoY drop in 2025 and a further -58.3% so far in 2026, indicating a shifting priority away from its foundational technology. Despite this, there's an emerging focus on 'Printed Circuits & Electronic Assemblies,' which, while a smaller portion at 12.5% of the portfolio, saw a remarkable +100.0% YoY growth in 2026, suggesting a pivot towards more integrated electronic solutions.
