"Original concepts" are of course compounded from concepts that came before. But what makes a concept original in my definition, is that the combination of the known concepts used has not been disclosed before. If there is utility to such an "original concept", this also enhances to the originality, as this utility obviously was not brought in connection with the combination that is novel per se. In other words, the utility also inherits originality from the novelty of combination, but simultaeously adds to the originality by rendering the ontology of the new compounded concept richer. Does this make sense to you?
