DEFINITION

Classification: 426/651

(under subclass 650) Subject matter involving an oleoresin or essential oil.

(1) Note. This subclass provides for essential oils which are claimed, disclosed or which historically have been used as flavoring agents, even when they have been derived from a single source. For example, citrus oils are classified here rather than in the 532-570 Series of Classes even though the patent does not disclose their use as a flavoring agent.
