Company patents
Preh GmbH
Preh GmbH's patent strategy reveals a surprising shift away from its core automotive and computing interfaces, with significant declines across most categories in 2025 and so far in 2026, including an 80.0% drop in Input/Output & User Interfaces (32.7% of portfolio) and a 20.0% decline in Vehicle Powertrain Arrangement (24.5% of portfolio) in 2025. Despite this, the company maintained its patenting in Switches and Pulse / Digital Logic Circuits in 2025 and 2026, suggesting a subtle, sustained focus on semiconductor components.
