Patent NL-1914-5367
This link from the Netherlands Patent Office Register to Espacenet leads to an error page. This is a very odd case. There is in fact another Dutch aero patent, filed slightly beyond the period of our primary interest, having this number, found by way of of manually searching the number, on Espacenet, seeing the title on the original, along with NL 62.7 and "vlietuigen" in the claims, then title searching within the Netherlands Patent Office Register, and finding it there as well. Both patents are found within the Netherlands Patent Office Register. Our own Espacenet link protocol applied to this patent number leads to said other patent. See Patent NL-1919-5367. Two aero-patents of the same number is likely a fluke. The fraction of links from Netherlands Patent Office Register to Espacenet is still an issue being examined. This Patent NL-1914-5367 may or may not actually have another number.
The date granted is missing from this particular patent record in the Netherlands Patent Office register.
