Company patents
STMICROELECTRONICS (ALPS) SAS
STMICROELECTRONICS (ALPS) SAS's patent strategy reveals a notable shift away from core computing and semiconductor areas, with significant declines in categories like Computer Security (-75.0% YoY in 2025), Pulse / Digital Logic Circuits (-33.3% YoY in 2025), and Computer Hardware Architecture (-25.0% YoY in 2025). While most categories show a downward trend, the company has seen a 50.0% increase in Amplifiers patents so far in 2026, indicating a potential refocus within semiconductor components, and a 200.0% YoY growth in Routing, Switching & QoS in 2024, which then declined sharply, suggesting an exploratory but not sustained interest in communications infrastructure.
