STEGO Group triumphs in landmark patent dispute in China

Victory before the Supreme Court in Beijing

After an intensive dispute before the Supreme Court in Beijing, Wenzhou Natural Automation Equipment CO., LTD. was sentenced to a fine and an injunction in the second instance. The company had copied the patented locking mechanism of the STEGO filterfan FPI/FPO 018/118 without authorisation. This mechanism ensures that the fans are securely fastened in the mounting recess without the need for tools.

STEGO filterfans are used in a wide range of safety-related applications where temperature control of enclosures and technical equipment is crucial. From industrial production plants to data centres, these filterfans ensure trouble-free operation and protect against potentially dangerous overheating events. By utilising patented innovations such as the FPI/FPO 018/118 series locking mechanism, users can rely on a proven and certified solution that safely and reliably supports their critical applications.
