Company patents
SMA Solar Technology AG
SMA Solar Technology AG's patent strategy is heavily concentrated in core electrical power technologies, with Power Distribution & Storage (47.5% of portfolio) and Power Conversion (DC/AC, DC/DC) (42.4% of portfolio) dominating, both showing significant year-over-year fluctuations but a recent decline in 2026 so far. Interestingly, while core areas like Electrical Measurement and Photovoltaic (Solar Cells) are seeing declines, the company is showing an emerging focus in Cryptographic Mechanisms, which saw a 100.0% year-over-year growth in 2026 so far, suggesting a surprising pivot towards secure communication within its broader energy solutions.
