Somewhat more than half answered zero (57.8%), which means that the rest, almost half the group, have turned to offshore providers for services related to trademarks, copyright or patents. More precisely, about a fifth said 1-10 percent of their work goes offshore (21.9%); some ship off 11-25 percent of it (10.9%); some offshore 26-50 percent (5.5%), and a handful do so with more than 50 percent of their IP work (3.9%).
