What is a Patent in South African Intellectual Property Law?

A patent in South African intellectual property law is a time-limited statutory monopoly granted by the Companies and Intellectual Property Commission (CIPC) under the Patents Act 57 of 1978, conferring on the patent holder the exclusive right to make, use, exercise, or dispose of the patented invention for a maximum of 20 years from the filing date. To be patentable, an invention must be new (novel), must involve an inventive step that would not be obvious to a person skilled in the relevant field, and must be capable of being used or applied in trade, industry, or agriculture. Patents are not granted for discoveries, scientific theories, mathematical methods, business methods, computer programs as such, presentations of information, plants or animals (other than certain micro-organisms), or methods of medical treatment of humans or animals — and they are obtained through a formal application, examination, and registration process administered by the CIPC, not through any court.

What a Patent Is in South African Law

A patent is a statutory monopoly granted by the state — not an absolute “right to the invention” but the right to exclude others from exploiting it commercially for a limited term. It gives the patent holder the exclusive right to exploit the invention commercially, typically for 20 years from the filing date, subject to the payment of annual renewal fees. The patent is territorial — a South African patent protects the invention only in South Africa, and separate protection is needed in any other country where the inventor wants coverage. The governing statute is the Patents Act 57 of 1978, administered by the Companies and Intellectual Property Commission (CIPC), which acts as the registrar of patents.

What Can and Cannot Be Patented

The Patents Act sets out a clear dividing line between what counts as a patentable invention and what is excluded from patentability, even if it is novel and useful.

Category	Patent status under the Patents Act	Examples
Patentable inventions	Allowed — must be new, inventive, and industrially applicable	Machines, devices, chemical compositions, manufacturing processes, methods of producing a new product
Discoveries and scientific theories	Excluded	A new physical law, a mathematical theorem, an unapplied observation
Mental acts, business methods, schemes and rules	Excluded	A new way of bookkeeping, a method of teaching, a board game rule
Computer programs as such	Excluded (program code is protected by copyright)	A new algorithm with no technical effect beyond the running of the program
Presentations of information and literary/dramatic/musical/artistic works	Excluded (protected by copyright)	A user-interface layout, a song, a sculpture, a novel
Plants, animals, and essentially biological processes	Excluded, except microbiological processes and the products of those processes	A new plant variety (protected separately under plant breeders’ rights), a breeding method
Methods of medical treatment of humans or animals	Excluded as methods, but the products used in such treatment can be patented	A new pharmaceutical compound may be patented even though the method of treating a patient with it cannot

A computer-implemented invention may still be patentable if it produces a technical effect beyond the running of the program itself — the program code itself is more naturally protected by copyright. Where the line falls in a borderline case is one of the questions that a registered patent attorney is best placed to assess.

The Three Patentability Criteria Explained

To be granted, an invention must satisfy all three of the criteria below. Failure on any one disqualifies the application, and a patent granted despite a failure on any criterion may later be invalidated.

Criterion	What it requires	Practical test
Novelty	The invention must not form part of the “state of the art” anywhere in the world before the filing date (or before any valid priority date claimed from an earlier Paris Convention or PCT application)	Has the invention, or anything enabling it, been made available to the public anywhere before the priority date?
Inventive step	The invention must not be obvious to a person skilled in the relevant art, having regard to what was already known at the filing date	Would a person skilled in the field arrive at the same invention simply by combining what was already known?
Industrial application	The invention must be capable of being made or used in some kind of industry, including agriculture	Can the invention be made or used in trade, industry, or agriculture?

Who Owns a Patent and What Ownership Means

Ownership defaults to the named inventor, but most employment contracts, commissioned-research agreements, and partnership arrangements vest ownership in the employer or commissioning party. The owner has the exclusive right to exploit the invention commercially, to license or assign those rights, and to sue for patent infringement in a competent court. Assignments and exclusive licences must be in writing and registered with the CIPC to be effective against third parties who later acquire conflicting rights.

How a South African Patent Is Obtained

South Africa follows a deferred-examination system, so examination is not automatic on filing. The procedural route through the CIPC runs along the following lines:

1. Conduct a prior-art search to confirm the invention is novel before filing — searching patent databases, published academic work, and publicly available product information.
2. File a complete patent application with the CIPC, including a specification (description, drawings if any) and claims defining the legal scope of the monopoly being sought.
3. Request substantive examination within the prescribed period — because South Africa follows a deferred-examination system, the application will not be examined until the applicant requests it.
4. Respond to any objections raised by the patent examiner; amend the claims where allowed and pursue the application through to acceptance.
5. On acceptance, the patent is registered and published; the 20-year term runs from the original filing date, not from the date of grant.
6. Pay the prescribed renewal fees annually to keep the patent in force — lapsed patents can usually be restored within a grace period after payment of the prescribed penalty.

Patent drafting matters at the outset. Drafting and filing done correctly the first time is usually cheaper and more effective than trying to fix a defective application later — a point that Burger Huyser Attorneys’ IP work, coordinated from the Linden head office through specialist patent and trademark consultant Stefaans Gerber, is built around.

How Long a South African Patent Lasts

Twenty years from the filing date, provided annual renewal fees are paid on time. The patent term itself is not extendable, although pharmaceutical patents may in defined circumstances be supplemented by a separate regulatory extension of the registration period for the underlying medicine, distinct from the patent term.

What “Patent Pending” and “Patented” Mean

“Patent pending” (or “patent applied for”) indicates that an application has been filed but not yet granted — it confers no enforceable exclusion rights. “Patented” indicates a granted patent; the number printed on a product is the patent number, not the application number. Misuse of these terms — particularly claiming patent protection for a product that is not actually patented — can attract regulatory action and damages claims under unfair-competition law.

Patents vs Other Forms of Intellectual Property

Patents sit alongside several other IP rights, each protecting a different feature of the same product. The table below sets out the principal South African IP categories and what each one covers.

IP right	What it protects	Where it is registered
Patent	Functional inventions and how things work	CIPC under the Patents Act 57 of 1978
Trademark	Brand identifiers (names, logos, slogans) used in commerce	CIPC under the Trade Marks Act
Copyright	Original literary, artistic, and musical works — automatic, no registration needed	Arises automatically on creation under the Copyright Act
Registered and aesthetic designs	The visual appearance of an article	CIPC under the Designs Act
Trade secrets	Confidential know-how with commercial value from not being publicly known	Protected through contractual confidentiality; no formal register

A single product is often protected by several IP rights simultaneously — the brand, the look, the underlying technology, and the marketing copy may each attract a different form of protection.

Patents, State Use, and Expropriation

The Patents Act allows the state to use a patented invention without the owner’s consent in defined circumstances, including public interest, public non-commercial use, anti-competitive practices, and national emergency. Any such state use is subject to the payment of compensation to the patent owner. The Patents Tribunal and the competent courts have jurisdiction to hear disputes arising from state-use orders and from any expropriation of patent rights.

Regional and International Routes

Because a South African patent protects the invention only in South Africa, inventors with overseas markets will need to look beyond the local CIPC route. The three main options are:

• Paris Convention: South Africa is a signatory, which gives priority rights for an earlier-filed application in another Paris Convention country.
• Patent Cooperation Treaty (PCT): South Africa is a signatory, which streamlines international filing through a single initial application.
• ARIPO: South Africa is a member of the African Regional Intellectual Property Organization, which allows a single application to designate ARIPO member states for protection.

A South African patent alone does not protect the invention elsewhere — inventors seeking overseas coverage must file separately, use the PCT, or use the ARIPO route.

Frequently Asked Questions

How long does a South African patent last?

A South African patent lasts 20 years from the filing date of the application, provided the prescribed annual renewal fees are paid on time. The term is fixed by the Patents Act 57 of 1978 and is not extendable, except in narrow pharmaceutical circumstances where a separate regulatory extension of the underlying medicine’s registration may apply.

What can be patented in South Africa?

A new, inventive, industrially applicable invention — meaning a product or process that has not been made available to the public before, that would not be obvious to a person skilled in the relevant field, and that can be made or used in trade, industry, or agriculture. Discoveries, scientific theories, mathematical methods, business methods, computer programs as such, mental acts, presentations of information, and methods of medical treatment cannot be patented.

Do I need to register a patent in every country where I want protection?

Yes — a South African patent only protects the invention in South Africa. Inventors seeking protection elsewhere must file separately in each country, use the Patent Cooperation Treaty (PCT) for a streamlined international application, or apply through ARIPO for designated African states.

Can I patent a computer program or a business method?

Generally no. Computer programs as such and methods of doing business are excluded from patentability in South Africa. A computer-implemented invention may be patentable if it produces a technical effect beyond the running of the program itself, but the program code itself is more commonly protected by copyright.

Who owns the patent — the inventor or the employer?

Ownership defaults to the named inventor, but most employment contracts and commissioned-research agreements transfer ownership to the employer or the commissioning party. The assignment should be in writing and registered at the CIPC to be effective against third parties.

How do I enforce a South African patent?

A patent owner enforces rights by bringing an infringement action in a competent South African court, which can grant an interdict (injunction), damages or an account of profits, and an order for delivery-up or destruction of infringing goods. Burger Huyser Attorneys coordinates enforcement through its IP consultant and its general litigation practice.
