• Danish Patent and Trademark Office -- Danish Patent and Trademark Office (the present one) -- Jørgen Burghardt tells us the data/office goes back to 1864; a reform in 1894 seems not to have made a big difference. he analyzed foreign filers in a sample of Danish patents.
• Danish patent classifications -- The same or very similar to the German one. Notably, klasse 77 refers to aeronautics.

Terms for dates found on patent originals:

• beskyttet fra (protected since) = submittal date, application date in Denmark, aside from any foreign priority date which might be relevant
• ustedt (issued) = grant date
• bekendtgjort (made known, or announced) = publication date
• Tillægspatent (til . . .) = additional patent (to . . .)
• Varigheden regnes fra den (date) = The duration is calculated from the (date)
• “Fortrinsret paaberaabt fra den 15. December 1915, Indleveringsdag for Ansøgning i Norge.” (“Preferential right claimed from 15 December 1915, filing date for Application in Norway.”) ; that is, an example of an international priority date reference, in this case pertaining to an earlier filing in Norway.
