Subsection (a) [Maine cite subsection (1)] does not render ineffective any term, and subsection (c) [Maine cite subsection (3)] does not render ineffective any law, statute or regulation, that restricts outright sales of general intangibles other than payment intangibles. They deal only with restrictions on security interests. The only sales of general intangibles that create security interests are sales of payment intangibles.

5. Terminology: "Account Debtor"; "Person Obligated on a Promissory Note." This section uses the term "account debtor" as it is defined in Section 9-102 [Maine cite section 9-1102]. The term refers to the party, other than the debtor, to a general intangible, including a permit, license, franchise, or the like, and the person obligated on a health-care-insurance receivable, which is a type of account. The definition of "account debtor" does not limit the term to persons who are obligated to pay under a general intangible. Rather, the term includes all persons who are obligated on a general intangible, including those who are obligated to render performance in exchange for payment. In some cases, e.g., the creation of a security interest in a franchisee's rights under a franchise agreement, the principal payment obligation may be owed by the debtor (franchisee) to the account debtor (franchisor). This section also refers to a "person obligated on a promissory note," inasmuch as those persons do not fall within the definition of "account debtor."

Example 2: A licensor and licensee enter into an agreement for the nonexclusive license of computer software. The licensee's interest in the license agreement is a general intangible. If the licensee grants to a secured party a security interest in its rights under the license agreement, the licensee is the debtor and the licensor is the account debtor. On the other hand, if the licensor grants to a secured party a security interest in its right to payment (an account) under the license agreement, the licensor is the debtor and the licensee is the account debtor.
