Company patents
Sonova AG
Sonova AG's patent strategy reveals a strong, albeit declining, focus on its core Loudspeakers & Microphones technology, which constitutes 86.4% of its portfolio but saw an 18.2% decline in 2025 and a 64.4% decline so far in 2026. Surprisingly, while most categories show a significant decline in patenting activity in 2026, Speech Processing experienced a remarkable 125.0% growth in 2025, suggesting a potential emerging focus despite its subsequent sharp drop so far in 2026.
