Company patents
Liebherr-Components Biberach GmbH
Liebherr-Components Biberach GmbH's patent strategy shows a surprising decline in core manufacturing areas, with Gearing & Transmissions and Bearings & Shafts, each representing 20.5% of their portfolio, both experiencing a significant -66.7% decline in patent filings so far in 2026 compared to 2025. This suggests a potential shift away from traditional mechanical components, while emerging areas like Electric Motors & Generators and Machine Testing show modest, albeit not rapidly growing, activity.
