Inadmissable claim amendments
The court of the commissioner of patents, seated in Pretoria, has handed down judgment in the matter of Sasol Dyno Nobel (Pty) Limited v African Explosives Limited. The court had to decide whether, in patent infringement actions, the reliance by a defendant on an allegation that a patent includes claims made in conflict with the provisions of Section 51 of the Patents Act no. 57 of 1978 constitutes a competent defence.
