You are best off talking to Christopher Freeman about this - he is an authority on it. http://www.sussex.ac.uk/spru/profile19724.html I am not aware of any data tabulating patents by SES of the inventor.
One problem with the sociology of innovations and inventions is that there is no comprehensive statistical information about it, so it is rather difficult to understand the overall proportions of things. You really have to study a particular industry in detail in order to understand about it. Mostly, there's data on patent and copyright applications (which may not be lodged by the actual inventor; many inventions do not get patented). The patterns of innovation and invention are susceptible to all sorts of ideological claims lacking solid evidential support. An additional problem is that these days people get called "engineer" although they haven't got a real engineering qualification. I don't talk about it really, because if I start talking about "patents and copyright" people get the wrong idea :-)
