Why is a complete history of the patent required for reexamination?

A complete history of the patent is required for reexamination to ensure that the USPTO has all relevant information to make an informed decision. The MPEP 2219 states: “A copy of any disclaimer, certificate of correction, or reexamination certificate issued for the patent must also be included, so that a complete history of the patent is before the Office for consideration.

This requirement serves several purposes:

  • Provides a comprehensive view of the patent’s legal status
  • Ensures all modifications and corrections are taken into account
  • Helps examiners understand the full context of the patent
  • Prevents potential oversights or misunderstandings during reexamination

By having the complete history, the USPTO can conduct a thorough and accurate reexamination of the patent, considering all relevant factors and changes that have occurred since its initial issuance.
