Of course it is an infringement. The specific rights and interests infringed depend on who has the right to use the logo.

Customers say that you sell fake goods. Most likely, this logo is the logo of some Nike products. In this case, you are indeed suspected of selling fake goods. If you want to defend, you can only prove that you clearly stated that this is not Nike.

Here you have to prove that you do not produce or sell counterfeit products. As for infringing on other people’s copyrights, it is not a big deal. Anyway, neither Nike nor Irving will sue you
