This initiated a phase of consideration of the interrupter gear concept in the Imperial German Army Air Service ("Luftstreitkräfte"). Fokker was heavily involved in this process but the story of his conception, development and installation of a synchronization device in a period of 48 hours (first found in an authorized biography of Fokker written in 1929) has been shown to be not factual. The available evidence points to a synchronisation device having been in development with Fokker's company for perhaps six months prior to the capture of Garros' machine. Additionally there were patents filed in France, Germany and Austria-Hungary as far back as 1910 which show a very similar device to that pioneered by Fokker. Author A. J. Weyl suggests that Fokker – or more probably someone on his production team – was aware of these patents. One patentee, Franz Schneider and his employer LVG, later sued Fokker in the German courts and won their case; but Fokker (by now in America) refused to pay up.
