Derwent Innovations Index combines patent information from the Derwent World Patents Index with patent citation information from the Derwent Patents Citation Index. It covers over 23 million basic inventions and 51 million patents drawn from over 48 patent-issuing authorities worldwide. Derwent Innovation Index enhances searchability and discoverability of patent data by adding valuable metadata to the patent record: concise titles that describe the invention and its novelty, abstracts about the claim and novelty of the invention and patent families (applications for the same invention in countries around the world are linked together in one record)
