Company patents
Knowles Electronics, LLC
Knowles Electronics, LLC's patent strategy reveals a surprising shift away from its core 'Loudspeakers & Microphones' category, which, despite representing 81.2% of its portfolio, has seen a significant decline in new patents, with a -53.7% YoY drop in 2025 and a further -47.4% decline so far in 2026. This suggests a potential re-evaluation of priorities, as other smaller categories like 'Amplifiers' also show recent declines, while 'Power Conversion (DC/AC, DC/DC)' and 'Magnets & Inductors' have seen a complete halt in new patenting since 2025.
