I don't think America surpassing Britain in any category was solely due to copyright laws. I would bet it was more of an issue of the UK absorbing a huge brunt of the wartime activity during that period.
To use two Asian countries: it's my understanding that Japan has had a lot of technological success while at the same time employing copy-protection practices (from what I remember in my Nintendo days). China is not at Japan's development stage yet but do you believe China, barring a change in how they enforce copyright, will be as much of an innovations leader as Japan was in its heyday?
