Indianapolis University of Indianapolis sued The Trustees of Indiana University on August 11, 2026, in the Southern District of Indiana, Case No. 1:26-cv-01669-JPH-MKK, alleging federal trademark infringement, unfair competition, and trademark dilution over IU’s use of “IU INDY” for the former IUPUI campus – a phrase the south-side school says is too close to its federally registered UINDY mark.

The Complaint (below) opens as “an action for infringement of U Indy’s well-known federally registered trademark ‘UINDY.’” UIndy has used UINDY in commerce since 2002 and owns a family of live Principal Register registrations, including U.S. Reg. Nos. 2,755,827 (Class 41 educational services; first use June 3, 2002; registered August 26, 2003), 3,327,194, 3,756,194 (clothing), 3,865,804, 4,039,095, and 6,969,975. After IU and Purdue unwound IUPUI in 2024, IU began branding the downtown Indianapolis campus as IU INDY – including, contemporaneous reporting notes, on athletic goods – and filed intent-to-register applications for IU INDY, IU INDY and design, and IU INDY JAGUARS (Serial Nos. 98/413,770, 98/413,774, 98/413,777, and 98/414,051), which published on October 22, 2024.

UIndy opposed those applications at the Trademark Trial and Appeal Board on February 19, 2025 (Opposition No. 91297078). The federal complaint now takes the fight out of the Trademark Office and into the Southern District. As pleaded in the public accounts of the Complaint, the two schools compete for the same students in the same city; UIndy alleges “confusion and deception in the marketplace and diversion of potential students and customers of U Indy to IU,” and says it has already seen mix-ups among students, job applicants, delivery drivers, and FAFSA filers. IU’s media office has declined to comment on the litigation. An answer has not been filed.

UIndy seeks to stop display, distribution, marketing, and promotion under IU INDY, plus damages. Two Indianapolis universities, one transposed pair of letters, one federal trademark docket. Stay tuned for updates.
