I want to know the answer to the following question:
Because of their patent, what didn't Siemens & Halske have to give Bell?
All the background I'm provided with is that "The value of the Bell patent was acknowledged throughout the world, and patent applications were made in most major countries, but when Bell had delayed the German patent application, the electrical firm of Siemens & Halske (S&H) managed to set up a rival manufacturer of Bell telephones under their own patent.". Is that enough to answer the question?
