NL 62.7
Klasse 62. Groep 7
This classification is absolutely aero-pertinent. Keyword wings is prompted by Patent NL-1919-6062. Incidentally, this relatively specialized classification was found by linking to Espacenet, and viewing a patent original, after having found said patent, via simple NL 62(as we call it), by entering 62 within the "IPC field" on BPP eRegister (rvo.nl) of the Netherlands Patent Office.
Note: Our reports on this patent classification may for a time "deceptively small". In rare cases, the Netherlands Patent Office "IPC" 62 results will include patents which are indeed pertinent, but in which auto-generated Espacenet links are not viable. We have found that what we call NL 62 was applied retroactively within the Dutch data, in a manner bridging the antique Dutch IdT classification with contemporary (to us) Espacenet IPC-based manners of data collation.
It may be that almost all, though not all, solidly aero Dutch patent material will fall into patent classifications which are subcategories of "Indeling der Techniek Klasse 62", and that this was the broadly aero-inclusive "Klasse".
