It is confirmed that micro-organisms, and non-biological and microbiological processes and the products thereof constitute patentable subject matter in South Africa.
Section 25(4)(b) of the Patents Act provides as follows:
"(4) A patent shall not be granted
(a) ...
(b) for any variety of animal or plant or any essential biological process for the production of animals or plants, not being a micro-biological process or the product of such a process".
This provision is interpreted to mean that the following do not fall within the exclusion:
- micro-organisms
- micro-biological processes and the products of such processes
- non-biological processes for the production of animals or plants.
