I believe there is a document that ties Bungie and ATVI together at the hip beyond a reasonable doubt. Go back thru the posting or on Google and you will discover a document that specifically states ATVI will cover expenses regarding such matters. Also, I believe ATVI placed one of there chosen people on the board of Bungie. These two items in my mind leave no doubt what relationship exists in reality and the date the relationship began.
Someone must believe there is a precedent possible or it would have been classified accordingly.
On a side note. Several weeks before the Kavanaugh debates I was watching the news and President Trump was speaking about Judge Kavenaugh. He spoke and said he wanted a Justice that would uphold the Constitution and IP and protect the holders of patents. I thought this was a timely statement. President Trump could have said and the VA, gun rights, immigration, or a plethora of other topics . Rather, he specifically stated and "IP and patent holders."
