Dilution is an important concept when conducting a trademark search. When a mark or term revealed in the search results is diluted, small differences in a proposed mark may be sufficient to avoid a likelihood of confusion. But dilution cannot be accurately evaluated unless you first accurately evaluate the relatedness of the goods or services. Like other likelihood of confusion factors, similarity of the mark, relatedness of the goods and services, and strength directly impact each other. And dilution only occurs when multiple marks sharing a common element in connection with related goods and services peacefully co-exist with each other on the Principal Register of the Trademark Office.
Because BOB includes the relatedness of goods and services factor, it also accurately evaluates the presence of dilution in the search results.
