They certainly didn't copy the real life patch of the unit.
There's little doubt that NovaLogic's trademarked fictional logo was the inspiration for their logo.
And right or wrong, they hold a trademark. I'm unaware of it being routine in such cases to question the very valdity of a trademark that they've applied for and recieved. The only question I suspect they're going to be asking here is if this is a violation of this trademark, not if NovaLogic should've ever been granted it in the first place.
