Derwent Innovations Index® facilitates rapid, precise patent searching, letting you conduct patent and citation searches of inventions in chemical, electrical, electronic, and mechanical engineering.

This resource merges the value-added patent information from Derwent World Patents Index® with the patent citation information from Derwent Patent Citation Index®. You can use additional descriptive information and coding to quickly grasp a patent's significance and its relationship to other patents. Reduce duplication of R&D; track competitors' activities; detect and avoid patent infringement; identify potential gaps in the marketplace and possible licensing opportunities.
