Company patents

Sandvine Corporation

Sandvine Corporation's patent strategy reveals a surprising shift away from its core communication technologies, with significant declines in its two largest categories: Routing, Switching & QoS (down 28.6% YoY in 2025) and Network Management & Monitoring (down 33.3% YoY in 2025). While most categories show a decline, Network Security & Access Control stands out as an emerging focus, with 4 patents so far in 2026 after a 100% YoY increase in 2024, indicating a potential pivot towards security solutions.
