  • “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.
  • the Szellemi Tulajdon Nemzeti Hivatala database in anglophone setting, choosing the Patent option, among the Advanced search on the left of the page, and using patent classification “V/h” as the keyword
  • Original .pdf drawn from Szellemi Tulajdon Nemzeti Hivatala database
  • (Virtual or direct analogue access to Szabadalmi Kőzlőny will facilitate the gathering of other data.)
