What are Guidance Headings in CPC schemes and how are they used?
Guidance Headings in CPC schemes are used to provide additional structure and clarity within the classification system. According to the MPEP, guidance headings may be provided in several ways:
- “When a large part of a subclass relates to a common subject matter, a guidance heading indicating that subject matter may be provided at the beginning of that part.“
- As a title, without any associated symbol, of subject matter preceding several main groups.
- To describe common subject matter of several main groups.
These guidance headings help users navigate the classification scheme more effectively by grouping related content and providing context for the classification entries that follow. They are particularly useful in complex or extensive subclasses where additional organization can improve understanding and searchability.
