The similarity search uses the CPC code(s) assigned to a publication to find all publications classified under the same code(s). It also uses the IPC codes, US PCL codes, citations (shared citations, cited and citing), the extended family (shared priority numbers) and concepts if available. The patents that are located, sorted automatically by relevance, will share at least one of these criteria. Each located family’s relevance score can be displayed in the hitlist.
From the list of results, use the KWIC tab to view the criteria used for the similarity search.
