Company patents
ebm-papst Mulfingen GmbH & Co. KG
ebm-papst Mulfingen GmbH & Co. KG's patent strategy shows a surprising shift away from its core areas, with significant year-over-year declines in patenting for Pumps (Centrifugal) (-66.7% so far in 2026) and Electric Motors & Generators (-88.9% so far in 2026), which together represent over 67% of its portfolio. While overall patenting seems to be slowing, there's an emerging focus on Business Methods & Fintech and Power Distribution & Storage, both showing 2 patents so far in 2026 after periods of no activity.
