4. Assignments of Perfected Security Interests. Subsection (c) [Maine cite subsection (3)] concerns assignment of a perfected security interest or agricultural lien. It provides that no filing is necessary in connection with an assignment by a secured party to an assignee in order to maintain perfection as against creditors of and transferees from the original debtor.

Example 1: Buyer buys goods from Seller, who retains a security interest in them. After Seller perfects the security interest by filing, Seller assigns the perfected security interest to X. The security interest, in X's hands and without further steps on X's part, continues perfected against Buyer's transferees and creditors.

Example 2: Dealer creates a security interest in specific equipment in favor of Lender. After Lender perfects the security interest in the equipment by filing, Lender assigns the chattel paper (which includes the perfected security interest in Dealer's equipment) to X. The security interest in the equipment, in X's hands and without further steps on X's part, continues perfected against Dealer's transferees and creditors. However, regardless of whether Lender made the assignment to secure Lender's obligation to X or whether the assignment was an outright sale of the chattel paper, the assignment creates a security interest in the chattel paper in favor of X. Accordingly, X must take whatever steps may be required for perfection in order to be protected against Lender's transferees and creditors with respect to the chattel paper.

Subsection (c) [Maine cite subsection (3)] applies not only to an assignment of a security interest perfected by filing but also to an assignment of a security interest perfected by a method other than by filing, such as by control or by possession. Although subsection (c) [Maine cite subsection (3)] addresses explicitly only the absence of an additional filing requirement, the same result normally will follow in the case of an assignment of a security interest perfected by a method other than by filing. For example, as long as possession of collateral is maintained by an assignee or by the assignor or another person on behalf of the assignee, no further perfection steps need be taken on account of the assignment to continue perfection as against creditors and transferees of the original debtor. Of course, additional action may be required for perfection of the
