Keywords: Change of category (allowed) - novelty (no - unambiguous implicit disclosure)
Catchwords:

1. A claim to the use of a compound A in a process for preparing compound B has no broader scope than a claim to a process for preparing compound B from compound A (see point 4).

2. The use of a compound A in a process for preparing compound B in order to reduce the formation of impurities is not necessarily a functional technical feature in the sense of decision G 2/88, and does not, therefore, in all circumstances confer novelty to the subject-matter of a claim containing it (points 5.3 to 5.5)
