Slovak Wikipedia indicates (we think) that it was "published" or "described" in January 1906.[1]

OR they got a second patent after this 1905 one. It had a basket and could carry a person, according to this photo.[2]

Here we have one of many cases in which the modern Hungarian entered website data gives “Repülőgép” while the original shows “Röpülőgép”. To the best of our knowledge, this has to do with “Röpülőgép” coming later to signify “Airplane” whereas, during the period on which we are focused “Röpülőgép” signified “Aircraft” more generally. In the case of this patent, it matters particularly in that we are talking about a helicopter rather than an airplane.

  • “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 seemingly 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.
