This paper provides an analysis of global patenting trends using the most comprehensive data currently available. Among other things, it finds that subsequent patent filings – additional filings of the same invention, mostly in additional countries – contributed considerably to the growth in filings worldwide, pointing to globalization as one important driver of filing growth. However, no single factor can fully explain the marked increase in the use of the patent system.
