Hey, Thanks for letting me know. I'll update the site to not have anything related to LEGO or MINI Figures. Big Fan of them and just wanted to make this as a fun side project.
Thanks for taking it the right way. Trademarkia is a good site to search for trademarks. You could probably use the word "mini" or even "figure" but they might have trademarked those put together. It's worth looking into.
I launched a product slogan years ago and got chased down by IBM, of all people. That wasn't fun. I wound up having to license my own tag line from them to settle the trademark dispute, even though it wasn't actually infringing (it was a different trademark class, hardware, and I was making software.) Then, my attorney explained that, while possibly winnable, taking on that case would cost $50,000.
