All LERXs are LEXs. But not all LEXs are LERXs.
Perhaps it's the aero engineer talking but I dislike the grouping of LERX into leading edge devices and I dislike the idea of calling all these leading edge devices leading edge extensions.

- LERX is inherently a vortex generator and the vortex can be generated by any aerobody that creates a pressure delta and the vortex can interact with any body regardless of if its a wing, a feature does not have to be dedicated to generating the vortex to have the same effect as a LERX, case in point the front section of J-36's cranked delta is very much a wing (lifting body) even though it acts like LERX to the rear delta. LERX is therefore a very ambigious thing.
- Leading edge extension by wording implies something that need to extend out from the leading edge, but a leading edge notch or a dog tooth does not extend from the leading edge so it's weird to call it a leading edge extension, leading edge device is more accurate.

Not sure if legit, but this was posted on FB:

Is it just me, or it looks not unlike that weird tandem VTOL patent from one year ago?

Could you link to the patent in question by any chance?

But for now I'll take all of it with a grain of salt.
