Orica Mining Services SA (Pty) Ltd v Elbroc Mining Products (Pty) Ltd (233/2016) [2017] ZASCA 48; [2017] 2 All SA 796 (SCA); 2017 BIP 1 (SCA) (31 March 2017)

The Supreme Court of Appeal held that the correct approach to interpreting patent claims is to read them in the context of the specification and to apply a purposive construction.

Procedural Posture

Civil Appeal / Appeal From the Court of the Commissioner of Patents

Legal Issues

  1. 1 Whether Elbroc's drill rig infringes Orica's South African Patent number 2001/10382.
  2. 2 How the term 'between' in the patent claims should be interpreted.
  3. 3 Whether the carriage must be 'linearly between' the props to fall within the patent claims.

Ratio Decidendi

The Supreme Court of Appeal held that the correct approach to interpreting patent claims is to read them in the context of the specification and to apply a purposive construction. The court found that the word 'between' in the claims does not require the carriage to be 'linearly between' the props. The specification expressly allows for the carriage to be generally between the props, including situations where there are more than two props or where the carriage is offset. Both expert witnesses agreed that the optimal solution is linear positioning, but this is not essential for the invention's functionality. The court rejected Elbroc's literal interpretation and found that Elbroc's drill...
