If you are a registered user of the Patent Review Processing System (PRPS) you may have encountered the same problem I did.  When logging in, I can see some matters where the petitions can be viewed, but other matters where the petitions are not viewable.  It is my understanding that this is due to a limitation in the current software that allows for views of up to 10 documents.  The petition may well be scanned into the system, but is not viewable because it is entered after 10 other scanned documents.

It is my understanding that there is a software update to be implemented in the next couple of days that will fix this issue.
