The technical terms are actually how all patents are written, so nothing special there. I don’t approve of things like this being patentable at all, but I actually expect this to be novel the way it’s written.
However, no one needs to infringe upon it - it’s trivial to change something ever so slightly so as to not do exactly what’s described here.
I use NanoKVM and I’m quite happy with that. Also connected to the internal header so it can power on/off and edit BIOS.
As for security, I don’t allow its IP to open up any outgoing connections.
