There are prior art requests here that are not "valid" anymore as the aplication has since become a patent.
Example: Prior art request for US20120179309 "Data Improvement System and Method"?
I retagged it from pre-grant to post-grant, but dont think thats the solution. In this case, the patent seems to have narrow(ed?) claims, so maybe even the question itself is outdated.
Any ideas what to do with those questions?
