Is a German Hochschule able to offer a Ph.D.? Can German Hochschule offer a Ph.D.? I know that some of them can't, but does this apply to any hochschule or does it differ from one to another?
One further note to clarify is that using "Ph.D." to denote doctoral degrees in Germany is somewhat nebulous, as many of the doctoral degree-granting institutions in Germany do not award Ph.D.'s. Instead, the range of doctoral degrees is somewhat broader. For instance, the institution where I work offers the Dr. rer. nat. and the Dr.-Ing., but not a Ph.D. In fact, we are not even allowed to use the term "Ph.D." in our advertising of our doctoral degree programs.

So, if you are asking "can German universities award doctoral degrees," Pieter's answer above is correct. However, if you mean literally "can German universities award Ph.D.'s," I'd have to say the answer is essentially "no."
