Ad tech, answered from Google’s patents and the trial record
Ask how ad serving, auctions, viewability or invalid traffic actually work — and get an answer in which every claim carries the identifier of the document it came from.
What answers you was read, not remembered. The patents and exhibits bearing on your question are opened and read end to end, every time.
Every claim has an address. US10002184B2, PTX1646 — the identifier sits in the sentence, the original one click away.
You will see where the corpus ends. Nothing is invented to fill a hole: the gap is stated, then goes on the Evolution page and gets closed.
