Düsseldorf Regional Court has upheld a utility model infringement action brought by Swiss rights holder Huber+Suhner against US competitor Maxtena, and Düsseldorf-based distribution company Karl Kruse. Now, accessing the internet during a train ride without loss of connection is increasingly common in Germany.

The case concerns a technology for antennas that sit on the roof of trains, stabilising the wifi connection for passengers during the journey. Huber+Suhner is the owner of utility model DE 20 2015 009 331 U1. The defendants were the US manufacturer Maxtena and the Düsseldorf-based franchise dealer for electronic components, Karl Kruse.

According to JUVE Patent information, there are no further pending proceedings internationally.
