Derwent Innovations Index (DII) combines the Derwent World Patents Index with the Patent Citation Index. DII allows for precise searching of over 14 million patents from 40 issuing agencies worldwide by topic, title, patent numbers, classification codes, inventor, assignee and compound. Most entries have links to abstracts and PDFs of the original patent applications with full text and images. For each patent, DII provides links to patents cited by the inventor and examiner as well as later patents that cite it. Using the Cited Patent Search option, researchers can search directly for patents that cite another patent. As part of the Web of Knowledge platform, DII also links to related journals, conference proceedings, and books that cite the patent.
