"Does anyone know if the "partnering efforts" are with one or more of the companies that eDigital is presently in litigation with?"

Nobody here could possibly know such confidential information.

Asking management at EDIG would not yield an answer either.

When it happens, look for a press release.

If you have not already done so, I suggest:
