How do I properly identify a patent or application in an assignment document?

According to 37 CFR 3.21, a patent assignment must identify the patent by patent number. For patent applications:

• National applications: Identify by application number (series code and serial number)
• International applications designating the US: Identify by international application number
• International design applications designating the US: Identify by international registration number or US application number

If the assignment is executed before filing but after the application is executed, it must identify the application by inventor name(s) and invention title. For provisional applications not yet filed, identify by inventor name(s) and invention title.

The MPEP suggests including language like: I hereby authorize and request my attorney, (Insert name), of (Insert address), to insert here in parentheses (Application number , filed ) the filing date and application number of said application when known.
