A comprehensive study of technological change

MIT News  August 2, 2021 Researchers at MIT have provided predicted yearly performance improvement rates for nearly all definable technologies by creating a correspondence of all patents within the US patent system to a set of 1757 technology domains. A technology domain is a body of patented inventions achieving the same technological function using the same knowledge and scientific principles. The domains contain 97.2% of all patents within the entire US patent system. From the identified patent sets, they calculated the average centrality of the patents in each domain to predict their improvement rates, following a patent network-based methodology tested […]
