Company patents
Nagravision S.A.
Nagravision S.A. appears to be significantly scaling back its patenting efforts across nearly all categories, with a striking decline in core areas like Pictorial / Video Communications (down 81.8% in 2025) and Network Security & Access Control (down 75.0% in 2025), which together represent over 67% of its portfolio. While there was a brief surge in Web & Cloud Service Protocols in 2024 with a 150.0% YoY growth, this was followed by a complete cessation of patenting in that category in 2025, indicating a broad shift away from new patent filings.
