I'm not sure the document released actually reflects the claims in the articles. It looks like the intent is not to delay them forever, just to make sure that they don't look silly for allowing any more patents that don't make sense (e.g. perpetual motion machines) through by putting them through more review. I think they should heavily scrutinise all patents, and so ideally shouldn't need a process like this, but at least putting the patents which are most likely to be bad is better than not scrutinising any patents thoroughly.
