Automatic perfection. Section 9-309 [Maine cite section 9- 1309] lists various types of security interests as to which no public-notice step is required for perfection (e.g., purchase- money security interests in consumer goods other than automobiles). This automatic perfection also extends to a transfer of a health-care-insurance receivable to a health-care provider. Those transfers normally will be made by natural persons who receive health-care services; there is little value in requiring filing for perfection in that context. Automatic perfection also applies to security interests created by sales of payment intangibles and promissory notes. Section 9-308 [Maine cite section 9-1308] provides that a perfected security interest in collateral supported by a "supporting obligation" (such as an account supported by a guaranty) also is a perfected security interest in the supporting obligation, and that a perfected security interest in an obligation secured by a security interest or lien on property (e.g., a real-property mortgage) also is a perfected security interest in the security interest or lien.

e. Priority; Special Rules for Banks and Deposit Accounts. The rules governing priority of security interests and agricultural liens are found in Part 3, Subpart 3 (Sections 9-317 through 9-342) [Maine cite sections 9-1317 to 9-1342]. This Article includes several new priority rules and some special rules relating to banks and deposit accounts (Sections 9-340 through 9-342) [Maine cite sections 9-1340 to 9-1342].
