Hyper Tech is a term used for advanced technology. Tony Stark is often asked to speak on hypertech.
On March 11 at three o'clock Tony was going to hold a seminar for hyper tech. That morning Tony was in his spa with Veronica Benning in a therapy secession. James Rhodes reminded him of the seminar before Whirlwind and Dreadknight attacked the Iron Man Armory. It is unknown if Tony actually got to the seminar since his place started on fire.
Hyper Tech is not well defined and is just a small reference in "And the Sea Shall Give Up its Dead".
Hypertech is the name of a real car engine company. However, it is unlikely that the reference was product placement.
