The answer according to the invention is correct, Ernst says. but gemäβ is a word that makes a connection that is not very well defined, and a rewrite as in the third answer may be the way to go. The meaning is definitely "in the sense meant in this patent description. The URL below has an example where erfindungsgemäβ means "do the way we say to do in this patent document" Here it means "use the kind of thing that we describe in this patent document". Suggestion: "a hose as specified / described in this document" or "fulfilling the requirements of this invention" Best wishes, Nancy
