These were the primary source of patent listings and categorization of patents filed and documented by the Belgian state, that is, patents filed in Belgium. This nation is under-represented within espacenet. Classification information too was found by way of the volumes Recueil (Spécial) Des Brevets d’Invention. From the 1800s to shortly after 1900 these volumes were known as the "Recueil Spécial des Brevets d'Invention", then the Special reappeared on the cover of the 1917-18 volume but not the title page.
Use of this resource is straightforward though time-consuming. It is purely analogue, at present, with the pages generally not existing, anywhere, as image files, not to mention digital searchability by way of text content.
At least in the later years, each year has two volumes, the index material for the two volumes being included at the end of the second volume. As with the French Bulletin Officiel de la propriété industrielle & commerciale, the volumes are sectioned into months, and the months are sectioned according to invention categories.
One searches the indexes, by patent title, inventor name, or field, such as "Aviation", such an example naturally often overlapping with patent title, or titles. Finding particular patents sought, perhaps following references made within other patents, Belgian or otherwise, is not difficult. Finding new material is also rather simple. Cross-tasking can be a matter leading to some complications if time is of the essence.
At present, particularly in the case of Belgian material pertinent to the years we are studying, this is the most efficient manner in which to find the patent number, and thereby conceivably to request access to the original.
The volumes of Recueil des Brevets d'Invention and the original patents are housed at the AGR 2 - Cuvelier facility in Brussels. The Recueil (Spécial) des Brevets d'Invention volumes are also to be found at the STIC library of the USPTO.
One peculiarity of the idexes found within these volumes has to do with the word choice involved in the search. A search of the word "aéroplane", for instance, will yield broad results, all of which are pertinent, only roughly half of which will have the word actually in the title and-or in the descriptive summary. All will be pertinent to aircraft. A few will go beyond BE K, usually the classification most pertinent to us, and into classifications BE J or BE L. This happens even though an a priori look at the BE K summary itself may have led to the word choice. The results are always pertinent to the airplane.
