This is a common source of confusion for South African inventors and entrepreneurs, who sometimes believe an early-stage idea can be "locked down" with a patent before it's even built. Understanding the actual bar helps set realistic expectations, and highlights why keeping an idea confidential through an NDA matters in the earlier stages before a patentable invention actually exists.

Frequently Asked Questions
Can a business method or an app idea be patented in South Africa?
Generally not on its own — abstract business methods and mere ideas fall outside what's patentable; a specific technical implementation may qualify.
What does "novel" mean in the context of patent law?
The invention must not have been publicly disclosed anywhere in the world before the patent application is filed.
How long does patent protection last in South Africa once granted?
A South African patent generally lasts for 20 years from the filing date, provided the required renewal fees are paid throughout that period.
