“Publication/disclosure” will be treated as “date granted”, for now. The “Megjelent (year). évi (month) hó (day)-én”, that is “Released (month) (day), (year)”, given on the original, is seemingly always later, and we do not know the 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.

Reference is made to "his first"("elsoőbbsége") patent filed 1912-06-20. Though no national reference is made, there is no Ludwig Schmidt patent appearing earlier in the Hungarian data. The predecessor is likely Austrian. Patent AT-1912-63049 has been deisgnated as the parent of a patent family inclusive of this patent.

Regarding the inventor's name, "Schmidl Ludwig" is found on the Hungarian original, though it is westernized to "Schmidt Ludwig" through the preceding search process. See Schmidl Ludwig results on Espacenet for the best overall results.
