Catalogue de Brevets d'Invention - Belgian

Like the French Catalogue des Brevets d'Invention, these Belgian catalogues of invention patents seem to have served a role auxiliary to that of a more thorough national compendium, in the Belgian case that is the Recueil des Brevets d'Invention. (We've made almost exclusive use of this latter resource, in that it is more thorough and is available both within the STIC holding and at the AGR 2 - Cuvelier facility in Brussels.)
