PatentCluster

Instead of giving the search user thousands of patent search results, PatentCluster search engine groups similar patents together into clusters. Clusters help you see your patent results by topic so you can zero in on exactly what you’re looking for or discover unexpected relationships between patents. You don't waste time scrolling through page after page without a clear understanding of categories and relationships within the patent search results.The clusters help you find results you may have missed or that were buried deep in the ranked list.
