What is the significance of the ‘Fields Searched’ section in an International Search Report?

The ‘Fields Searched’ section in an International Search Report (ISR) is crucial as it indicates the scope and thoroughness of the international search. According to MPEP 1844:

“The Search Report should list the classification identification of the fields searched.”

This section typically includes:

  • International Patent Classification (IPC) symbols
  • Other classification systems used (e.g., CPC)
  • Keywords or search terms used
  • Databases consulted

The ‘Fields Searched’ information helps applicants and patent offices assess the comprehensiveness of the search and may guide further searches or examinations. It also provides transparency in the search process, allowing others to understand the extent of the prior art considered.
