What other differences should be evaluated when deciding to file a U.S. national phase application versus a bypass application?

-A U.S. national phase application will be examined under the international "unity of invention" standard, while a bypass application will be examined under U.S. restriction practice.

-When filing a national phase application (subject to certain limitations), you would not ordinarily need to submit a new IDS for references cited in the International Search Report and corresponding Written Opinion, whereas you would if you instead filed a bypass application. 

-When filing a national phase application (subject to certain limitations), you would not ordinarily need to submit a copies of foreign priority documents (you will likely need to submit verified translations however).  You will need to submit such copies if you instead filed a bypass application.

-Unlike a national phase application, you will not need to submit the filing fees of a bypass application the same day it is filed.
