The English name of this blog is "domain name". It's very original, because this blog is mainly about... domain names ;-)
Someone registers the trademark "domain name", for (among other things) electronic communication services, legal services, etc. Is the name of this blog infringing this trademark?
Of course not (even under French law!!!)
(Thanks to Frederic Glaize, French Trademark Attorney, for spotting the amazing registration below)
