This is a more comprehensive search where search is made for marks which are not only identical but also marks which might be considered deceptively similar to the mark in question. This type of search, as the name suggests, is to ensure that there is absolute ‘clearance’ before the said trademark could be applied.

Such a search would be made using several keywords, combinations including aurally similar ones to alleviate the possibility of deceptively similar marks. A search would also generally be conducted online including domain names to determine if there are any marks deceptively similar to the subject mark being used.
