Once you start using your trademark, you should focus on your strategy for defending it:   You must use your mark as filed. It is important to know that when a trademark is not used for a continuous period of 5 years from the date of its registration, it can be deleted from the trademark register. The deletion of the trademark can be requested by any third party, without even having to have a legal interest. Be alert for potential tampering or tampering. The existence of your own mark in the trade mark register does not imply the automatic rejection of a subsequent similar/same mark as yours. Take action against those who do not respect your trademark rights.
