Well this seems messy. Hasbro has decided to sue DC over their use of the name Bumblebee for one of their characters. The DC character Bumblebee dates back to 1977 and as we know Transformers Bumblebee is from 1984, however they seem to be fighting over a 2015 trademark filing.

I don't pretend to understand the American legal system but this seems like shaky ground for Hasbro to stand on since DC's character predates Transformers Bee.
