- Exergue
- 1. The concept of bioisosterism has to be applied with caution when deciding upon inventive step (No. 4.2.3.3).
2. When deciding upon inventive step in relation to pharmacologically active compounds, what is essential is not whether a particular substructure of a chemical compound is replaced by another known isosteric one, but whether information was available on the impact of such a replacement on the pharmacological activity profile of the specific (group of) compound(s) concerned (No. 4.2.3.5).
ORDER
for these reasons it is decided that:
1. The decision under appeal is set aside.
2. The case is remitted to the Examining Division with the order to grant a patent on the basis of the following documents:
- Claims 1 to 11 for all the designated contracting states except Spain, as filed by fax on 13. September 1996;
- Claims 1 to 8 for Spain, as filed by fax on 13. September 1996;
- a description to be adapted accordingly.
