I spent a lot of time doing that at the time.

Other Polaroid patents were of the form: 'we've patented a white wagon - now we want a patent for a red wagon' and then a follow up patent asking to patent a 'red wagon with a white stripe'. In other words, offering no real innovation (and to my mind, obvious to one skilled in the arts).
Yes, the US Patent system is (and has been for sometime) broken and doesn't attempt to evaluate patents other than looking for prior art. It leaves it to the courts to resolve things and they don't always get it right. We badly need patent reform because there are now far too many patent trolls.
BTW, did you work for Polaroid?
