Innovation includes both INPADOC and Derwent patent family data. For an in-depth description of the difference between these two family systems, see the Patent Families article.
Unlike some other search systems, Innovation does not maintain records organized into patent families. Instead, it allows users to search and retrieve individual documents, and collapse their list of patents into Derwent families, INPADOC families, or by common application number. See the Family Search Features section for more information.
