Are you sure about that last part? I thought whitebox engineering was completely acceptable in hardware. Additionally the patent says: A method of issuing and executing instructions out-of-order in a pipelined microprocessor in a single processor cycle... In other words, it's hardly a patent on OoO.

Most of the OoO patents are lapsed. This one is recent: http://www.freepatentsonline.com/y2015/0026442.html http://www.freepatentsonline.com/y2015/0026442.html Who knows what it's patent status is. One can always do an in-order design. Has the advantage of determinism and ease of covert channel analysis.
