What search tools are recommended in MPEP 904 for patent examiners?

MPEP 904 recommends several search tools for patent examiners to conduct thorough prior art searches:

  • Classification indices (e.g., CPC, USPC)
  • Patent databases (e.g., USPTO, EPO, JPO)
  • Non-patent literature databases
  • Internet search engines
  • Specialized technical databases

The MPEP emphasizes the importance of using multiple tools: “In addition to searching the invention as described in the disclosure, it is necessary to search for all claimed elements.” (MPEP 904)

Examiners are encouraged to use a combination of these tools to ensure comprehensive coverage of potential prior art sources.
