- Abstract, compressed: The recombination of new and existing technological capabilities is a source of technological novelty. The US Patent Office defines inventions as bundles of distinct technologies brought together to accomplish a specific outcome. The Office identifies the technologies constituting inventions by labeling them with technology codes. The technology codes support a combinatorial analysis of the novelty of inventions, informed by evolutionary economics and complexity science. The technology codes give consistent definitions of technologies for 220 years of inventive activity. They identify distinct technological capabilities, defining technology spaces, marking the arrival of technological novelty, measuring technological complexity, and empirically grounding the study of technological change. This paper discusses these patent technology codes and some statistics about them. We highlight the discriminating nature of the codes and their usefulness in characterizing processes by which technological capabilities generate novelty.
