Company patents
Elisa Oyj
Elisa Oyj's patent strategy reveals a surprising emerging focus on Power Distribution & Storage, which, despite a sharp decline so far in 2026 (YoY -90.9%), saw a significant surge in 2025 with 11 patents after no activity in prior years, representing 10.1% of its total portfolio. While core areas like Wireless Networks (47.1% of portfolio) and Network Management & Monitoring (30.3%) remain dominant, the substantial 150.0% YoY growth in Telephone Equipment patents so far in 2026 suggests a renewed emphasis on foundational communication hardware, contrasting with the general slowdown in its primary network-related categories this year.
