Abstract

[useful annotation re: German pats] confirm my cable this morning: "The german patent office decided all incandescent lamps with carbon filaments are subject to Edison's patents." The Kolnische Zeitung stated "Today the German patent office decided in a case of demand of nullity made by Swan against TAE's principal German patent. The attack of Swan was caused by the declaration of the German Edison Co that all incandescent lamps having carbon conductors are subject to Edison's patents. Swan demanded that the fundamental paten should be made void or at least restricted in such manner that other p eople could also make carbon conductors independently...The patent office reject the 'demand of nullity' as also the 'demand for restriction' and condemned Swan to costs. It furthermore declared that all incandescent lamps with filaments of carbon are exclusively the property of Edisn's patents." Batch says, "How is that for high? I believe this will be the death of the Autrian lawsuit also."
