Finding that prior registrations of marks including the term ULTIMATE "do not conclusively rebut the Board's finding that ULTIMATE is descriptive in the context of this mark"
Stating that "[a]s to strength of a mark . . . [third-party] registration evidence may not be given any weight . . . [because they are] not evidence of what happens in the market place"
Holding that "little weight is to be given [to third-party] registrations in evaluating whether there is likelihood of confusion" because "[t]he existence of these registrations is not evidence of what happens in the market place or that customers are familiar with them"
