If no common issue exists (overlapping period of time) between the subsequent claim
                  and the prior claim, we cannot establish the date of entitlement and the date of onset
                  on the new application before the end of the period being considered on the claim
                  that is pending before the court.
               
               If the claim that is pending in court, either under the same or a different title,
                  contains no common issue, the FO routes the subsequent claim to the appropriate DDS
                  with a transmittal sheet annotated as follows: “Do not release any denial notices
                  or make any systems inputs. Onset cannot be established prior to (fill-in date of
                  last administrative decision of the Commissioner on the prior claim).”
