How does the filing date affect the content of a reissue oath/declaration?

The content requirements for a reissue oath/declaration can vary based on the filing date of the reissue application. The MPEP 1414 states:

“Much of the required content of a reissue oath or declaration will differ based on the filing date of the reissue application.”

Specifically:

• For reissue applications filed on or after September 16, 2012, refer to MPEP § 1414.01 for additional requirements.
• For reissue applications filed before September 16, 2012, refer to MPEP § 1414.02 for additional requirements.
• For supplemental reissue oaths or declarations in applications filed before September 16, 2012, refer to MPEP § 1414.03.

It’s crucial for applicants to determine which set of requirements applies to their specific reissue application based on its filing date to ensure compliance with the appropriate regulations.
