Pierce Butler, Salem Trust Company v. Manufacturers' Finance Company…
“ In a case where, as here, the later assignee has made no inquiry of the debtor in advance of taking his assignment, there is no analogy between the giving of notice by the first assignee to the debtor and the taking of possession of tangible personal property by a purchaser. It is impossible in any real sense to transfer possession of accounts receivable or the like, and, as to them, an assignee does not become clothed with the indicia of ownership as does one taking possession of tangible things. ”
