Patent HU-1917-80687

This is an addition to Patent HU-1917-76911. It also makes reference to non-Hungarian priority date 1917-02-16. This may be a German priority date.
Seemingly, this Hungarian addition, and its Hungarian patent, were filed on the same day. Each of the patents has its analogous non-Hungarian equivalent, as reflected in the different priority dates. The non-Hungarian patents were filed slightly more than four months apart. The later of the non-Hungarian filings may or may not have been considered a per se addition.

- “Publication/disclosure” will be treated as “date granted”, for now. The “Megjelent (year). évi (month) hó (day)-én (or án)”, that is “Released (month) (day), (year)”, given on the original, is nearly always later, and we do not know which legally constitutes the patent’s being “granted”. Fortunately, filing date data is clean and simple and consistent between the data page and the original.
