A notable issue involving our investment is to be proven in 5 words...at this stage of the game.

rephrase...

A notable issue involving our investment are the 5 words that need to be addressed as being self-evident...at this stage of the game.

If one considers a new method of how to power manage the use wheels of a vehicle ....is it necessary to detail the piston or an armature(note there could be multiple power origination) of the engine generating the power?....Or would one simply note it as of the received processed engine input having a self-evident method to be addressed by "one of ordinary skill in the arts".

"of the received processed sound electrical signals" amounts to an engine detail prior to the sole memory consideration, that one of ordinary skill would have to address.
