What are the consequences of reopening prosecution after appeal in a patent application?

Reopening prosecution after appeal in a patent application can have several consequences:

  • Withdrawal of the appeal: The appeal is automatically withdrawn when prosecution is reopened.
  • New Office action: The examiner must issue a new Office action addressing all claims on appeal.
  • Additional prosecution: The applicant may need to respond to new rejections or arguments, potentially extending the examination process.
  • Possible petition opportunity: If the applicant disagrees with the reopening, they may have grounds to file a petition under 37 CFR 1.181.

As stated in MPEP 1207.04: “The examiner should never reopen prosecution in an application after appellant has filed a brief and the examiner’s answer has been mailed, unless an amendment under 37 CFR 41.33 necessitates such reopening.”
