What information should be included when citing a prior application in MPEP ¶ 2.05?

When citing a prior application using MPEP ¶ 2.05, specific information must be included. The MPEP instructs examiners:

“In brackets 1 and 2, insert the application number (series code and serial number) and filing date of the prior application, respectively.”

This means that when referencing a prior application, the examiner should provide:

• The application number, including both the series code and serial number
• The filing date of the prior application

Including this information ensures clear identification of the specific prior application being referenced.
