OutKast has reached a settlement to end a lawsuit against an electronic dance music duo calling itself ATLiens – the same name as one of the hip hop duo’s best-known songs.

In court filings, attorneys for Big Boi (Antwan Patton) and André 3000 (André Benjamin) say they’ve “reached agreement on a general settlement framework” to resolve the case, in which they sued the lesser-known group in 2023 for infringing trademarks to the famed portmanteau.

“The parties are hopeful that the case will be fully resolved within ninety days … if not sooner,” lawyers for both sides write in the filing. Specifics of the settlement were not disclosed, and neither side immediately returned requests for more details.

Released in 1996, ATLiens is OutKast’s second studio album, featuring the same-named song as one of the singles from the LP. The album spent 33 weeks on the Billboard 200, while the title song reached No. 35 on the Hot 100 and spent 17 weeks on the chart.

Nearly two decades later, the duo went to court in 2023 against ATLiens, an Atlanta-based EDM that allegedly started using that name in 2012 and later registered it as a trademark. OutKast’s lawyers said the name (a combo of “aliens” and their hometown of Atlanta) was a novel linguistic term, and that rival group was confusing music fans by using it.

“The word ATLiens was invented by OutKast. Before OutKast created it, it was not used in the cultural lexicon and did not exist,” their lawyers wrote at the time. “Defendant’s use of the ATLiens mark is likely to cause confusion, to cause mistake, or to deceive the public.”

In filing the case, OutKast claimed that, thanks to the rival group’s elaborate stage costumes, fans might literally think they’re Big Boi and André 3000. “The duo comprising defendant performs with masks on, thereby concealing their identities such that consumers will mistakenly believe that the members of defendant are one and the same with – or at least somehow connected to – plaintiff.”

ATLiens responded in 2024, denying all wrongdoing and rejecting that OutKast has “any trademark rights whatsoever in the ATLIENS mark.” But the case has largely been paused for more than a year as the two sides worked on reaching a settlement.
