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.

CAB International, together with our partner, the European and Mediterranean Plant Protection Organisation, have been publishing the Maps for over 50 years. From their conception, recognising the need for accurate data on the distribution of plant diseases and pests of economic or quarantine importance, the Distribution Maps have been the authoritative source for this vitally important global geographic information.
