How does the USPTO define a “complete search” for patent applications?
The USPTO defines a “complete search” for patent applications as one that covers the disclosed invention and the state of the art as thoroughly as possible within reasonable time and with reasonable effort. According to MPEP 904.02:
“The U.S. Patent and Trademark Office has traditionally attempted to provide the most thorough search possible within the limitations of time and expense.”
This means that examiners are expected to conduct a comprehensive search that balances thoroughness with practical constraints. The search should cover all aspects of the claimed invention and relevant prior art to ensure a fair and accurate examination process.
