Derwent Innovations Index (DII): Unique Patent Information for Innovation and Research

Did you know that over 80% of the technical information in patents is not published anywhere else? The NIH Library provides access to Derwent Innovations Index (DII), which indexes chemical, electronic, and mechanical engineering patents from 1963 to present.

DII includes more than 51 million inventions from 59 worldwide patent-issuing authorities and other sources. Patent records are enhanced with a descriptive title, a structured abstract discussing the novelty and claims, and added indexing. Non-English language patents include translations.
