Fun fact:

“The term S-Bahn was until 14 March 2012 a registered wordmark of Deutsche Bahn, where at the request of a transportation association the Federal Patent Court of Germany ordered the wordmark to be removed from the records of the German Patent and Trade Mark Office.[9] Prior to the said event Deutsche Bahn collected a royalty of 0.4 cents per train kilometer for the usage of the said term.“
