A popular misconception. No submarine to it. The facts are already out. Suggest you read the 300+ page Initial Decision by Chief Administrative Law Judge Steven McGuire in the matter of FTC -v- Rambus. Rambus clearly had the patents and the industry thought they could steal them. The popular misconceptions are due to whorish trade press in league with criminally colluding memory makers to rape and pillage this small company.
I remember at the time they were modifying their pending patents to cover what was being publicly discussed at JEDEC. That's submarine.
