The idea that inventions are solutions to specific technical problems is foundational to innovation research—yet, so far, there is no systematic way of measuring which problem an invention addresses. The problem that a battery overheats, for instance, may be solved through inventions in electrochemistry, materials science, or mechanical engineering. In existing patent data, these solutions would appear unrelated, because the data are organized around the technology employed, not the problem addressed. This missing problem dimension means we cannot observe which technical problems attract competing solutions from different fields, how broadly firms search across alternative solution paths, or how inventive labor is divided between those who recognize problems and those who develop solutions. This project constructs a new dataset that makes the link between inventions and the problems they address visible at scale.
