Sec. 3.21  Identification of patents and patent applications.

    An assignment relating to a patent must identify the patent by the 
patent number. An assignment relating to a national patent application 
must identify the national patent application by the application number 
(consisting of the series code and the serial number, e.g., 07/123,456). 
An assignment relating to an international patent application which 
designates the United States of America must identify the international 
application by the international application number (e.g., PCT/US90/
01234). If an assignment of a patent application filed under 
Sec. 1.53(b) is executed concurrently with, or subsequent to, the 
execution of the patent application, but before the patent application 
is filed, it must identify the patent application by its date of 
execution, name of each inventor, and title of the invention so that 
there can be no mistake as to the patent application intended. If an 
assignment of a provisional application under Sec. 1.53(c) is executed 
before the provisional application is filed, it must identify the 
provisional application by name of each inventor and title of the 
invention so that there can be no mistake as to the provisional 
application intended.
