| interest in them to another buyer (B-2) or to a lien creditor |
| (LC). However, for purposes of determining the rights of the |
| debtor's creditors and certain purchasers of accounts or chattel |
| paper from the debtor, while B-1's security interest is |
| unperfected, the debtor-seller is deemed to have rights in the |
| sold receivables, and a competing security interest or judicial |
| lien may attach to those rights. See Sections 9-318, 9-109 |
| [Maine cite section 9-1318, section 9-1109], Comment 5. Suppose |
| that B-1's security interest in certain accounts and chattel |
| paper is perfected by filing, but the effectiveness of the |
| financing statement lapses. Both before and after lapse, B-1 |
| collects some of the receivables. After lapse, LC acquires a |
| lien on the accounts and chattel paper. B-1's unperfected |
| security interest in the accounts and chattel paper is |
| subordinate to LC's rights. See Section 9-317(a)(2) [Maine cite |
| section 9-1317, subsection (1), paragraph (b)]. But collections |
| on accounts and chattel paper are not "accounts" or "chattel |
| paper." Even if B-1's security interest in the accounts and |
| chattel paper is or becomes unperfected, neither the debtor nor |
| LC acquires rights to the collections that B-1 collects (and |
| owns) before LC acquires a lien. |
