The Trustees of Purdue University own several federally registered trademarks, including “Purdue,” “Boilermakers,”13 and various images of trains or locomotives.14 One such registered trademark for BOILERMAKERS claims a first use in commerce at least as early as in 1959, decades before Sports Beer Brewing Company filed an application to register the trademark with the state of Indiana in 2016.15 The Trustees of Purdue University filed a lawsuit in Tippecanoe County, Indiana, to enforce their trademarks.
