A domain name search can be launched at the same time as a trademark search.
It then allows you to know if the name that you want to use is already registered by a third party in the extension of your choice.

A domain name search can also be usefull anytime to have a concrete idea of the use of your name on the internet.
It then allows you to notice if a third party has registered a domain name identical to yours (or to your trademark) and it provides you with the date of the registration and a link to the website. By accessing the website we will be able to determine if the use of the domain name is made in bad faith and can lead to confusion with your company. Should it be the case we will advise you on the next steps and on your chances of success in recovering the domain name.
