Manual of Foreign Patents

The thorough annual indexes (Verzeichnis) contain a number of sections enabling the searcher to obtain complete data fairly readily starting from a knowledge of only the patent number, or the patent application number, or the applicant s name, or the classification. The Manual of Foreign Patents (263) contains an especially clear presentation concerning the German patent publications.

AAany of the patent publications in the Scientific Library of the Patent Office are to be found in no other library in the United States —so starts the preface to the invaluable Manual of Foreign Patents ...

Actually, there is no other library in this country where it is practical to attempt a thorough search of foreign patents. And no publication other than the manual is known to the writer which contains a concise, yet comprehensive, account of the patent publications of foreign countries, together with an indication of those obtainable at the Patent Office. 

The manual also includes, as its introduction, a unique article on Searching Foreign Patents, by Worischek (19). This is a survey of the broad subject which presents an interesting combination of the highlights and many unusual, but valuable, details garnered through years of experience.
