What happens after the submission of the prior art to the USPTO?

Examiners will consider all documents and comments contained in the peer review process submission and will give those documents and comments the weight the examiner deems appropriate. The examination process for these applications will be performed in a normal manner following established methods.

However, participating applications will be advanced out of turn for examination for the initial examination on the merits so the results of the pilot can be reviewed in a short time frame.
