2. Look up the words in the Cooperative Patent Classification (CPC) to find potential class/subclasses.
3. Review the Classification Definitions to verify the scope of the subclasses and notes
4. Retrieve and review issued patents using the CPC Classification you selected

7-Step U.S. Patent Search Strategy• Patent documents
5. Current U.S. patents - read the front page information on patents retrieved and review drawings and claims
6. Pending U.S. patent applications – read the disclosure and drawings
