Okla. Stat. tit. 12A, § 1-9-330
Oklahoma Code Comment
Section 9-330 is the successor to former section 9-308 . As under former section 9-308 , differing priority rules apply to purchasers of chattel paper who give new value and take possession (or, in the case of electronic chattel paper, obtain control) of the collateral depending on whether a conflicting security interest in the collateral is claimed merely as proceeds. The principal difference relates to the role of knowledge and the effect of an indication of a previous assignment on the collateral.
Section 9-330 also affords priority to purchasers of instruments who take possession in good faith and without knowledge that the purchase violates the rights of the competing secured party. Thus, a secured party who perfects a security interest in a promissory note by possession (even if not a holder in due course under Article 3) has priority over a secured party who perfects only by filing if the secured party in possession took possession in good faith and without knowledge that the transaction violates the rights of the other secured party. A holder in due course clearly defeats a secured party who perfects only by filing under section 9-331 and sections 3-305 and 3-306 .
In addition, to qualify for priority, purchasers of chattel paper, but not of instruments, must purchase in the ordinary course of their business. And a nonpossessory secured party also may defeat a competing possessory claim by inserting a notation on the instrument or tangible chattel paper indicating the security interest and giving notice that a sale would violate the rights of the secured party. See section 9-330(b), (d) , and (f) . These issues are replicated to the extent possible in the context of electronic chattel paper. See, e.g., James M. Swartz, Electronic Commerce and Issues in Buying Chattel Paper, 53 Consumer Fin. L.Q. Rep. 91 (1999).
