Lightsaber sound? Copyright issue?

When watching the trailer from 1.50 - 1.54 you can clearly hear the sound of a lightsaber.

How is this an isssue? Well the lightsaber is a brand of Star-Wars, having an items called a “LIGHT SABER” in another show would not be allowed, neither the sound as it belongs with it.

Sure now the sound is not from a sword but i keep wonder, is that really leagal?

as far as I am aware you can not copyright a sound. you can copywrite a phrase or a song or tune, but not a single sound. which frankly could’ve been made by any number of things. they could say they got that sound from a bee buzzing or something. I mean really.

It sounds very similar but it is not identical.

I mentioned the Xiaolin Showdown Roleplay toys emit a similar sound. I’m sure other toys do so aswell. So its nothing to worry about.

Alright guys thanks, just checking!
