Are there cases where an accepted paper is retracted for lack of originality?
By "revoked," I assume that you mean retracted. I have often heard of papers being retracted for plagiarism, but never for reinventing the wheel.  

I believe that the reason is, there are so many different ways to invent wheels, that it is almost always possible to tell if an idea is actually an independent invention.  A reinvention will likely use somewhat different terminology, have a different formulation of the problem, use different types of evidence, or whatnot.  There will be so many small differences, that it would be clear that the work is original, in the copyright sense, and not an academic fraud.

The fact that is it a reinvention of an idea that was already discovered elsewhere, however, means that it is likely to sink into obscurity once this fact is discovered... except... sometimes, a reinvention is not just a reinvention.  Sometimes, the reason for a reinvention is that an idea has not reached a community.  In that case, the contribution may not be the reinvention, but the importation of a mature body of work from elsewhere, in which case even a reinvention of a wheel may constitute a legitimate scientific contribution, in the form of bringing together two strands of research that complement one another and allow vital new progress to occur.
