This paper analyzes Chinese patenting abroad by using WIPO’s foreign-oriented patent family dataset and a respective enterprise questionnaire. It finds that by the turn of the century China emerged as major actor in terms of international patenting. While this is changing rapidly, the share of Chinese patents which get filed abroad is still a fraction of total patents filed at home and most patents still also only target one foreign IP office. Chinese foreign-oriented patent families are concentrated in a few technology fields, and a few Chinese firms are responsible for a large share of total Chinese patents filed abroad.
