[MCU] What happened to Obadiah's stun tech from Iron Man 1?

In IM1, Obadiah has a handheld device that temporarily paralyses someone with some kind of ultrasonic frequency. The tech looks like it would be highly useful in a number of situations, so why did Tony never develop it further?

Well Tony was busy developing the tech he cared about. He’s a genius, but he’s only one man, and there’s only so many fields he can develop at the same time. 

Additionally, it might be the case that the range of the stun weapon couldn’t be amplified, making it fairly useless for someone like Iron Man.
