Derwent Innovations Index is a global patent database within the Web of Knowledge platform. The database includes the Derwent World Patents Index as well as the Patent Citation Index. The Index includes information from 40 worldwide patent-issuing authorities, including data from 1963 forward. Included in the record for patents are links to patents citing a patent, as well as those patents and articles cited by the examiner. Among other features, the database includes an analysis tool for working with large groups of results.
To access Derwent Innovations Index, go to the Web of Knowlege database, click the drop-down arrow next to "Web of Science Core Collection" and select "Derwent Innovations Index".
Use these databases to search for and read the full text of U.S. and international patents. Start with SciFinder Scholar and the Derwent Innovations Index; after that, try one of the bolded databases depending on when and where the patent application was filed.
