Company patents
Fronius International GmbH
Fronius International GmbH's patent strategy shows a surprising shift away from its core "Welding & Soldering" category, which, despite representing 46.3% of its portfolio, has seen a significant decline in patenting activity, with a -66.7% YoY drop so far in 2026. Concurrently, while "Power Distribution & Storage" experienced a remarkable 160.0% YoY growth in 2024, its subsequent decline suggests a dynamic but currently decelerating focus in the electrical power sector, with most categories showing substantial year-over-year decreases in patent filings.
