What is a Patent Right in South African Law?

A patent right in South African law is the statutory exclusive right granted under the Patents Act 57 of 1978 to exclude others from making, using, exercising or disposing of a patented invention within South Africa, for a maximum term of 20 years from the filing date of the complete specification, subject to payment of prescribed annual renewal fees. The right is a creature of statute — there is no common-law patent right in South Africa — and is granted only after substantive examination and registration through the Companies and Intellectual Property Commission (CIPC). The right is also territorial: a South African patent protects only within South Africa, and the patentee must obtain separate patents in any other country where protection is sought.

The Statutory Framework: Patents Act 57 of 1978

Every patent right in South Africa derives from the Patents Act 57 of 1978, whose long title is “to provide for the registration, protection and administration of patents and for matters connected therewith.” The Act is administered by the Registrar of Patents within the Companies and Intellectual Property Commission (CIPC), which succeeded the former South African Patents and Trade Marks Office during the IP-administration transition. Because a patent is a creature of statute, the right cannot be broader than what the Patents Act defines it to be — a judge-made common-law patent right does not exist in South Africa.

The Patents Act treats a patent as a personal and territorial property right that may be assigned, licensed, mortgaged or otherwise transferred (section 25). It operates alongside the Counterfeit Goods Act 37 of 1997, which provides criminal sanctions for trafficking in counterfeit patented goods, and (internationally) alongside the Patent Cooperation Treaty (PCT), which South Africa honours as a route for filing internationally.

What the Patent Right Actually Is: Nature and Scope

The patentee holds an exclusive right to exclude others from making, using, exercising or disposing of the invention within South Africa. The right is framed as a right to exclude, not a positive right to make or use the invention — the patentee may still need other permissions (for example, regulatory approval under the Medicines Act for a pharmaceutical product) before the invention can lawfully be put on the market.

Three further features define the scope of every South African patent right:

A granted patent does not, by itself, require the patentee to work the invention in South Africa — but persistent non-working can trigger compulsory licensing under the Act (discussed below).

What a Patentable Invention Is

Section 25(1) of the Patents Act defines a patentable invention as one that is new, involves an inventive step, is capable of being used or applied in trade, industry or agriculture, and is not excluded by section 26.

Section 26 Exclusions — What Cannot Be Patented

The Patents Act expressly excludes the following from patentability:

• Discoveries and scientific theories
• Mathematical methods
• Schemes, rules or methods for performing mental acts, doing business or playing games
• A program for a computer as such
• Methods of treatment of humans or animals by surgery, therapy or diagnosis (other than products used in such methods)
• Certain plant or animal varieties

A technical implementation that includes a software component may still be patentable where it produces a technical effect beyond the normal interaction between software and hardware, but a pure software algorithm or business method as such is excluded.

How a Patent Right Is Granted: The Registration Path

An unregistered invention has no statutory protection in South Africa — only registration creates an enforceable patent right. The path runs through CIPC in Pretoria:

1. File a provisional specification with CIPC to establish an early priority date.
2. File a complete specification within 12 months of the provisional, ending with one or more claims defining the scope of the invention sought.
3. Request substantive examination within three years of the earliest priority date — if examination is not requested in time, the application lapses.
4. Pay annual renewal fees from the fourth anniversary of the filing date onward; failure to renew causes the patent to lapse and the invention enters the public domain.

The Limits of a Patent Right

Even a validly granted patent is subject to statutory limits built into the Patents Act. The most significant are:

State Use and Compulsory Licensing

The State Use provisions (sections 55–63) allow the Minister of Trade, Industry and Competition to authorise a government department or a state contractor to use a patented invention — on terms including the payment of a royalty to the patentee. Historically these powers have been used in public health contexts, and they remain a substantive area of policy and academic debate. Compulsory licensing may also be sought where the patent is abused, including where the invention is not worked in South Africa, or is worked predominantly outside South Africa, on terms set by the Commissioner of Patents.

Prior-User Rights and Private/Experimental Use

The exclusive right yields to prior-user rights: anyone who was using the invention in good faith before the priority date has a personal right to continue that use and is not liable for infringement. Acts done for non-commercial purposes — private use, or experimental use relating to the subject matter of the invention — are also not infringing.

What Patent Infringement Looks Like

Infringement falls into two recognised forms, both actionable in the High Court:

• Direct infringement: making, using, exercising, disposing of or importing the patented product or process without the patentee’s consent.
• Indirect infringement: supplying means relating to an essential element of the invention, knowing (or where it is obvious in the circumstances) that those means are intended for, and will be used for, infringement.

Relief available in the High Court includes an interdict (injunction), damages or a reasonable royalty in lieu of damages, delivery-up or destruction of infringing goods, and (in egregious cases) costs on a punitive scale. Criminal sanctions for trafficking in counterfeit patented goods are available under the Counterfeit Goods Act 37 of 1997. Technical questions may be referred to a court-appointed expert under the Patents Act.

Patent Right vs Other IP Rights

A patent covers one specific slice of the intellectual-property landscape. Knowing where patents end and trademarks, copyright, designs and plant breeders’ rights begin helps avoid the common misconception that any creative or commercial output is automatically a “patent.”

Working with a Patent Attorney in South Africa

Patent attorneys in South Africa must be registered with CIPC and admitted as such — patent work is restricted, and a general practice attorney without patent-agent registration cannot represent a client in patent prosecution. A patent attorney typically handles prior-art searching, drafting the specification and claims, responding to CIPC examination reports, renewing the patent, and advising on infringement and licensing matters. For international protection, the patent attorney coordinates filings through the PCT national-phase process in each country where protection is sought.

A patent right is one thing; the legal work that surrounds it is quite another. Burger Huyser Attorneys’ intellectual property practice, led by specialist consultant Stefaans Gerber (Patent & Trademark Attorney), supports clients across Gauteng with the contracts and disputes that sit around a patent portfolio — drafting and reviewing assignment, licence, commercialisation and IP-collateral agreements, advising on infringement and state-use matters, and assisting where a patent asset is being bought, sold or licensed. The firm’s IP practice is run from the Linden, Randburg head office (49 First Avenue, Linden, Randburg, 2194, telephone 011 888 0246, after-hours 061 516 6878). To discuss a patent or IP matter, contact the head office directly; for matters requiring registered patent-agent representation in front of CIPC, the firm will refer or co-operate with a patent attorney as needed.
