Here, between the 1914 filing date, of a patent filed by an American in Austria, and the 1921 date granted, we have the effect of Great War hostility. Incidendally, this this filed one day before the various patents making reference to what we have designated as Patent US-1913-04-21 George Raymond Lawrence, and it clearly draws from the same extreme elaboration on the airplane. We will treat it as a descendant.
