Two universities in the same city, competing for the same students, are now in federal court over the difference between UIndy and IU Indy.
On August 11, 2026, the University of Indianapolis sued the trustees of Indiana University in the U.S. District Court for the Southern District of Indiana. The complaint brings claims for trademark infringement, unfair competition and false designation of origin, and trademark dilution. The dispute is about the shortened name IU uses for its Indianapolis campus after the former IUPUI split in July 2024 into IU Indianapolis and Purdue University in Indianapolis.
The University of Indianapolis has registered UINDY in various forms for more than twenty years and says it has used the nickname for close to twenty-four years. IU applied to register IU INDY in February 2024, and a year later, in February 2025, the University of Indianapolis filed an opposition at the Trademark Trial and Appeal Board. That is where this started, and the federal lawsuit is the escalation.
Why one letter matters more than people think
Most business owners assume that if a name is not identical, it is fine. That is not the test. The test is whether ordinary consumers are likely to be confused about who is behind the product or service.
UIndy and IU Indy are separated by the position of one letter. The two schools sit in the same city, sell the same thing, and reach the same buyers through the same channels, including apparel worn at sporting events. According to reporting on the dispute, the confusion has already shown up in real life, including misdirected deliveries and prospective students showing up at the wrong campus.
That is the pattern to watch. Similar name plus same market plus same customer equals risk, no matter how small the spelling difference looks on paper.
Three lessons for a small business
Being first is worth something, but only if you claimed it. The University of Indianapolis had a registration going back to 2003. That is why it can bring a federal case instead of arguing about who used the name first. Common law rights exist, but they are harder and more expensive to prove.
Watch what other people file. The University of Indianapolis knew about the IU INDY application because someone was paying attention to the trademark register. Opposing an application before it registers is usually less painful than fighting over a name that has been in the market for years.
Documented confusion is the strongest evidence there is. Mixed up emails, misdirected orders, customers who thank you for someone else’s work. Save it. Screenshot it. That file is what turns a hunch into a case.
What this does not mean
A pending lawsuit is not a decision. Indiana University has not answered these claims publicly, and courts weigh many factors before finding a likelihood of confusion, including how strong the original mark is and how careful buyers are. Nothing here predicts the result.
What it does show is how expensive a naming decision can become after the fact. Both schools have invested in signage, apparel, recruiting materials, and websites. Whichever way this ends, someone spent money on lawyers that could have gone somewhere better.
If your name is close to someone else’s
Run a real clearance search before you print anything. Look at the federal register, at state filings, and at what is actually being used in your market. If you find something close, that is not automatically a stop sign, but it is a reason to get an opinion before you scale.
If you are already in market and something similar shows up, act early. The longer both names are in front of customers, the harder it is to unwind, and the more the fight is about money instead of names.
If you are not sure whether your name is too close to something already out there, book a free consultation and we will run a comprehensive search before you commit to anything. You can also see how our flat-fee trademark application packages work.
