Company patents
PIERBURG PUMP TECHNOLOGY GMBH
PIERBURG PUMP TECHNOLOGY GMBH's patent strategy shows a surprising stagnation in its core "Pumps (Centrifugal)" category, which accounts for 50.0% of its portfolio, with 0.0% year-over-year growth in 2024 and 2025, and a significant -60.0% decline so far in 2026. This suggests a potential shift away from its traditional focus, further evidenced by the complete cessation of patenting in "Electric Motors & Generators" and "Vehicle Body Fittings" so far in 2026, categories that previously represented 20.6% and 5.9% of its portfolio, respectively.
