How does the USPTO handle multiple pending reexamination proceedings for the same patent?

The MPEP 2254 provides guidance on handling multiple pending reexamination proceedings for the same patent:

• Multiple ex parte reexamination proceedings are generally merged into a single proceeding.
• If an inter partes reexamination is also pending, it takes precedence over ex parte reexaminations.
• The USPTO may suspend one proceeding in favor of another to promote efficiency.

The MPEP states: “If multiple ex parte reexamination proceedings are pending concurrently on a patent, the proceedings will generally be merged. If a reissue application is pending concurrently with a reexamination proceeding, the USPTO will usually merge the two proceedings.”

This approach ensures a coordinated examination and helps prevent conflicting outcomes.
