Questions on which to use the rejected tag:
The purpose of the tag is to focus community effort on finding prior art for prior-art-request which have not yet been rejected by the USPTO. Plus it's nice to celebrate success. The tag may be used if the application / patent was narrowed / rejected after a prior art request but without measurable contribution of this community to indicate that a prior-art-rquest question is no longer relevant / needs no more answers.
