Are Search Notes in USPC definitions exhaustive?

No, Search Notes in USPC definitions are not exhaustive. According to MPEP 902.02(a):

“Search notes are not exhaustive and do not limit the search but suggest additional fields of search.”

This means that while Search Notes provide valuable guidance for patent searches, they should be considered as starting points rather than definitive limits. Searchers should use these notes to expand their search scope but should not rely on them exclusively. It’s important to consider other relevant areas and use professional judgment when conducting a comprehensive patent search.
