Yes, a registered patent practitioner can withdraw from multiple applications simultaneously. The process is as follows:

• File a single request listing all affected application and patent numbers.
• Include the correspondence address for each application or patent.
• If applicable, provide new attorney registration numbers for each case.

According to MPEP 2560: “A request for withdrawal from representation in multiple applications or patents must be submitted in separate letters for each application or patent.” This ensures proper processing and documentation for each case.
