It appears the jetpack patents have changed hands again. I remember seeing these things on TV as a kid in the 70s, and as I recall the thing was invented in the mid-60s. Forty years later, it seems nobody's managed to increase the range significantly. Will the jet powered version pan out? Well, microjets have definitely made progress in the intervening years, but I can't recall any with the required performance. Jet packs: the transportation of the future, now and forever!
