How should I identify an international patent application in an assignment?

For an international patent application designating the United States, you must use the international application number in the assignment. MPEP 302.03 specifies: “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/US2012/012345.” This format ensures proper identification of the international application in the assignment document.
