I don't have the time, but if you're really interested in this question I highly recommend taking a look at various indexes of innovation. I had the same question myself a few years back and I was impressed with how innovative other countries are when you actually try to quantify what you're talking about.

The US doesn't necessarily come out on top all the time - or even most of the time.

The US excels at a lot of consumer-facing innovations, so I think that led me conclude that the US dominates in innovation. But there's a lot more to innovation than just consumer facing software.

The US also benefits from a history of massive government investments in R&D, mostly through the DoD. So that may be covering the any innovation deficit we have due to a weaker social safety net.
