Catchwords:
1. The Enlarged Board of Appeal limited its Orders in G 0002/88 (part (iii)) and in G 0006/88 explicitly to a claim to the "use of a known compound", in which a technical effect should be interpreted as a functional technical feature.

In the Board's view, this leaves no room for further expansion of this ruling to claims worded otherwise (Nos. 5.3.4 and 5.3.5 of the reasons).

2. The Board shares the view expressed in No. 3.2.3 of the reasons in T 0210/93 that the use of a process for a particular purpose is "nothing but that very same process" (No. 5.6 of the reasons).
