I thought Ericsson worked out that functionality in the 80's with Erlang.

Ericsson definitely implemented a system where dynamic code patching was possible. It wasn't designed for typical C ABIs though.

Patents don't really cover ideas or concepts.

A patent covers a specific set of steps to accomplish something.

So unless Erlang did it's code injection in the same/similar enough manner (very arbitrary) as this new implementation then it's not really relevant to the patent situation.

Looking at a few software patents out there, I beg to differ …

NB: *its code injection.
