A German proprietor of a lighting and sound system store provided a free and unsecured Wi-Fi network to his customers. One of them used this to offer a music album for free download. Thereupon Sony, the rights holder of the album, sued the shopkeeper. The ECJ now decided that he is not at fault.
The operator of a Wi-Fi network is not liable for copyright infringements committed by a third person. However, the ECJ stated that he could be requested to secure the network with a password. This is intended to prevent infringements by anonymous users.
