Company patents

Siemens Aktiengesellschaft

Siemens Aktiengesellschaft's patent strategy reveals a surprising shift away from its core strength in Industrial Control Systems, which represents 21.5% of its portfolio but has seen a consistent decline, including a -15.2% YoY drop in 2025. While many categories show a general slowdown in patenting activity so far in 2026, the sustained growth in Image Processing, with a +23.3% YoY increase in 2025, suggests an emerging focus on visual data analysis despite its smaller share (4.0%) of the overall portfolio.
