Hmm... this logo looks a little familiar...

I was working on my wife's computer and saw this icon in one of her browser windows:

It's for a web-based PDF program named OrbitNote that was released in January of 2022. I wouldn't say it infringes, but the similarity caught my attention.

It is probably further from the SS logo than the SS logo is from Prusa Slicer logo, so "infringement" would be an interesting discussion.

In the first place, logo idea of Slic3r is very generic.
I bet you can find same logo popping up in all colors all around the world for over a century.
