Company patents
Liebherr-Components Biberach GmbH
Liebherr-Components Biberach GmbH's patent strategy reveals a strong, consistent focus on core manufacturing components, with "Bearings & Shafts" and "Gearing & Transmissions" collectively accounting for 38.8% of its portfolio, despite a notable decline in filings for both categories so far in 2026 (YoY -66.7%). While there's a general trend of fluctuating and often declining patent activity across many categories, the company shows a surprising, albeit small, emerging interest in "Electric Motors & Generators" with a steady 1 patent filed in both 2025 and so far in 2026.
