American Home Products Corporation, Professor Roy Calne v Novartis Pharmaceuticals UK Limited, Novartis Pharma AG: CA 27 Jul 2000

The invention was a second medical use for a known drug rapamycin, which was found to have an immuno-suppressive effect. The court asked whether a claim to rapamycin should be construed to include derivatives.
Held: A person skilled in the art would be unable to say without experimentation that any particular derivative would have an immuno-suppressive effect. Applying the second Protocol question, it would have been absurd to ask whether, assuming that a derivative ‘worked’ in the sense of having an immuno-suppressive effect, it worked ‘in the same way’. That would really be to beg the question. Neither the product nor the process was new: the whole point of the invention was the newly discovered immuno-suppressive effect.
