Abstract: This paper examines whether geographic and structural proximity plays a role in the rate of trademark opposition. I draw the population of oppositions from both the EUIPO and USPTO which include approximately two hundred and one hundred and fifty thousand trademark applications that have been opposed respectively. Preliminary findings show that for the case of EUIPO (USPTO) home bias plays a significant role; i.e. a large share of oppositions come from opposes in the same country (state). Structural proximity also plays a significant role. Geographic and demographic distance also plays a role. The only study in trademark opposition is by von Graevenitz (2009) who uses data from EUIPO and provides significant insights on firms' behavior. This is the first study that examines the role of proximity in trademark opposition and also uses data from USPTO.  Findings point to significant spillovers that have potentially preceded trademark opposition. They are also relevant to the litigation literature where information failures have been identified as one of the main culprits of such behavior.
