While doing a patent search I've come across a lot of legalese. is there any benefit to transforming the plain English that I would use to describe my invention into the type of legalese that is found in so many patents?

In other words when writing a patent application can I just use plain English? Doing so would make my patent application different than all the ones that I've looked at which is what concerns me.

I've seen some that are so full of legalese that the true subject matter is almost incomprehensible. If nothing else I'm confident they could be explained more clearly without the legalese.

So is the use of legalese necessary? Is it a cargo cult situation? Can I ELI5 the entire application except the parts where it's necessary to use bigger words?
