We commit ourselves to registering the invention, which relates to slip- ringless transmission elements, without delay in Germany for patenting and to keep it secret until the application is submitted.[1] 2. The registration is in your and our names. The costs of the German applica- tions will be disbursed by us and are not to be charged in the event that there is a lack of success. 3. We commit ourselves, further, to instructing the firm Anschütz and Co. to draw up suitable designs for the apparatus and to develop them in its workshop. 4. We shall attempt to exploit the yet-to-be issued protection rights along the route of licensing or by an en-bloc sale, insofar as they do not regard the research area of the firm Anschütz & Co.

The statement of account for this occurs annually without interest on 31 De- cember, where the amounts received by us are to form the basis. The accounting as well as the payment are due by 1 March of the subsequent year at the latest. 7. If we should assign licenses to the relevant foreign patents in foreign countries for the field of work of the firm Anschütz & Co, then 3% are due of the incoming sums to us for the licenses.
