What are Definition Notes in USPC?

Definition Notes in USPC are supplementary information that accompany many of the class and subclass definitions. The MPEP describes two types of notes:

  • Supplementary Notes: notes that supplement definitions by explaining terms or giving examples
  • See or Search Notes: notes referring to related disclosures located in other classes or subclasses

The MPEP further explains the purpose of See or Search notes: The latter notes are termed “See or Search” notes and are helpful in explaining the limits of a class or subclass. They generally state the relationship to, and difference from, other identified subject matter collections.

It’s important to note that Search notes are not exhaustive and do not limit the search but suggest additional fields of search.
