Data
Description: This correspondence provide a link between finely defined patent classes based on International Patent Classification (IPC) into broader fields of knowledge, which, taken together, constitute what we refer to as the world’s technology space. We employ a novel approach to clustering patent technology classes based on inventors’ information. Our procedure is based on the likelihood that the same inventor produces inventions associated with different patent subclasses.
More detailed description of the procedure is available in "Global Innovation Spillovers and Productivity: Evidence from 100 years of World Patent Data" by Berkes, Manysheva, and Mestieri
