For some context most project graduate at 1 1/2 t 2 years, but some take longer, it just depends on the project. The IP clearance is important and you would need to show progress on this before you could graduate.
Well, I believe that we would be in the worst case in this because this is an older, established project with a long history and many files to be cleared. I don't expect overnight miracles. I would be comfortable if there were a plan to make slow, steady progress over the long haul. It does not take a major, superhuman effort; just steady progress But there no such plan and there is no such progress.
That is a road to failure. At this point, why should we expect anything to be different in a year? In two years? What is the event that will change the status quo?
