The comprehensive search casts a much wider and deeper net to reveal non-identical marks that are similar to yours and may pose a conflict. For example, if we were to search for LegalZoom, it would look for direct hits but also marks that sound alike or differ in spelling by 1 or 2 letters (for example: LegalBoom, EagleZoom, ZoomLegal, etc.). The comprehensive search goes beyond the USPTO in places like web domains and social media.
