Are Issue Batch Numbers still used for tracking patent applications?

No, Issue Batch Numbers are no longer used for tracking patent applications at the USPTO. According to MPEP 1303.01:

“Reference to an Issue Batch Number is no longer necessary because the Office no longer stores and tracks applications according to issue batches.”

This change reflects a modernization of the USPTO’s tracking and management systems for patent applications. Instead of using batch numbers, the USPTO now likely uses more advanced digital tracking methods to manage applications throughout the examination and issuance process.
