Well this type of interaction is what almost ever startupper/inventor wants to receive and then sell their technology to the big G.
Turns out the big G (Motorola ATAP at the time now Google ATAP) were a bunch of jerks who just wanted to know how our non-public technology worked. After flying from Bmore to Silly Valley .. filing our provisioinal patent and then them prying the info out of us with the bait of buying it we were quickly showed the door and told the race is one... better hurry.
I guess that's part of Google's R&D process...stomp on & treat the little guy like garbage!?!
YOu need to lawyer up if you don't have connections who are connected to X big brand. It's David vs. Goliath and Goliath will just crush you and your hopes and dreams.
