A knockout search, also referred to as a “quick and dirty search”, ONLY looks for the identical and semi-identical trademark. It will show both live and dead applications and registrations. This type of search can be done by you at the Trademark’s Office database or by an attorney, but it does not require a lot of time and it does not provide real advice. If the intended name exists for your products/services of interest, you cannot file it.
A clearance search is done by an attorney with specific tools and software. All applications and registrations are analyzed from different perspectives. It enables comparison phonetic, graphic and conceptually and it will provide advice from an experienced attorney and the possibilities of success and likelihood of confusion with others.
