From Inventing aviation

We have based this titular year on the the date at which the original says that the Austrian patent began to take effect, though the fact wasn't published until 1921 and the 1915-06-15 date granted was acknowledged retrospectively. The significant delay in publication of the patent was likely due to the circumstances of World War I and the likely bureaucratic backlog thereafter. Reference is made to a French patent registration 1913-04-24. This most directly refers to Patent FR-1913-438580.17636 and by implication to Patent FR-1911-438580.
