In the civil case between Min Hee-jin and Billy Leap Lab, the controversy over OOAK’s mission and logo has been presented as a rebuttal to the IllIT plagiarism allegations. OOAK is said to resemble the Canadian craft company One of a Kind in both its name and logo, drawing renewed scrutiny. Min Hee-jin’s team argues that the fingerprint-based logo and the “OOAK” abbreviation used for the brand bear significant similarity to One of a Kind’s branding.

One of a Kind reportedly uses a fingerprint as its logo and has used the “OOAK” acronym for event naming. Billy Leap Lab has criticized Min Hee-jin for acting out of personal gain and for allegedly harming other idols, attacking IllIT. The plaintiffs also allege that Min Hee-jin consulted Sejong Law Firm regarding the IllIT plagiarism issue during her time at Ador, and that the firm reportedly said the lawsuit would be difficult and rely on public sentiment.

Min Hee-jin’s side counters that, after IllIT’s debut, online comments suggested plagiarism was suspected by the public, media, and critics. They argued that focusing on the essence and issues shows similarities between IllIT and New Jeans, and that using terms like “copy” or “plagiarism” does not automatically amount to copyright infringement.
