Using newly collected patent assignment data for late nineteenth- and early twentieth-century Germany and a standard econometric approach from the international trade literature—the gravity model—we demonstrate the existence of border effects on a historical technology market. We show that the geographic distance between assignor and assignee negatively affected the probability of patent assignments, as well as the fact that a state or international border separated the two contracting parties. Surprisingly, we show that the effect of a state border within Germany was nearly as large as the effect of an international border.
