Abstract: L’application de l’analyse spectrale au domaine cliométrique a été jusqu’à présente restreinte. Elle est employée ici pour déterminer la périodicité des séries agrégées de brevets de la France, de l’Allemagne, de la Grande-Bretagne, des Etats-Unis et du Japon. Après avoir rappelé la méthode (I), nous examinerons les séries retenues, le traitement de ces séries et les résultats de l’analyse spectrale (II). Il sera alors possible de montrer les perspectives de ce type d’approche et de synthétiser un résultat majeur, à savoir l’existence d’un cycle unique, commun aux cinq pays, de type Juglar. / Spectral analysis has had limited applications in cliometrics to date. It is used here to determine the frequency of aggregate patent series of France, Germany, the United Kingdom, the United States and Japan. A reminder of the method (I) is followed by successive examination of the series chosen, the treatment of these series and the results of spectral analysis (II). It is then possible to show the prospects of this type of approach and to synthesise a completely new major result, that is to say the existence of a single Juglar type cycle, common to the five countries.
