Headnote:

1. Technical progress shown in comparison with marketed products as an alleged support for inventive step cannot be a substitute for the demonstration of inventive step with regard to the relevant closest state of the art. (Following T 181/82 "Spiro-Compounds/Ciba- Geigy", OJ 9/1984,401).
2. The possibility of a prohibition of experiments with animals in one Contracting State of the EPC is not a sufficient reason for declining the submission of test results in comparison with the closest state of the art if the inventive step can only be demonstrated in this manner.
