What are the key steps in conducting a thorough prior art search?

Conducting a thorough prior art search involves several key steps:

1. Analyze the invention: Understand the claimed invention and its key features.
2. Identify relevant classifications: Determine the appropriate patent classifications for the invention.
3. Search primary tools: Begin with classification indices and patent documents.
4. Expand to secondary tools: Explore technical literature and non-patent documents.
5. Use specialized tools: Employ technology-specific search tools if applicable.
6. Review and refine: Analyze search results and refine the search strategy as needed.

MPEP 904.03 states, “In all continuing applications, the parent applications should be reviewed for pertinent prior art.” This emphasizes the importance of thorough and comprehensive searching, including reviewing related applications.
