Selection of German Patents (DE)
up to series DE999,999
Dbase, being in progress
Last update: 30 November 2012
(Mixed language, pdf)
These files are based upon our archives dbase, which still is in progress. The aim is, to create a database of interesting patents. It does not claim, however, to be comprehensive, but it is used as a quick patent number reference.
And, of course, it is reflecting my personal interest.
German patents are known since mid 1950s: DExxx. Up to that period they carried:
D.R.P. xxx (Deutsches Reichspatent).
* The discovery (February 2006) of, until very recently, lost patent files (marked formally "not available"), passes a very strong indication, that the Allies, shortly after the end of the continental hostilities, may have manipulated the existence of these kinds of patent documents. Many of these carry a special stamp: Micro Filmed By FIAT. I have earmarked them with an additional suffix "ap"* (DExxxxxap) (please omit this suffix "ap", when you apply for patent files on the web) . We may be lucky, that these documents (partly being hand written) give us an inside vision as to how German patent applications were handled. * Consider also: VO vom 15.1.44 with its historical context and links to background information on the history of German patent legislation and, for example - DE762245 ap
Only the German "depatisnet" can provide these documents. The European patent database still is showing negative results.
For those searching in patent libraries, patents are to be entered like: DE123456, US1234567, GB123456, ...
We have, however, prevented the downside of successive numbering, and have add the number zero, as to hold a six-digit mantissa.
