Patenting in South Africa: Everything You Need To Know

Patenting in South Africa is administered nationally by the Companies and Intellectual Property Commission (CIPC) under the Patents Act 57 of 1978, which sets the patentability test (novelty, inventive step, industrial applicability), the application procedure (provisional followed by complete within 12 months, or a direct complete filing), the 20-year patent term from the effective filing date, and the infringement and revocation remedies available to patentees. An inventor or assignee can file directly, but most applicants instruct a registered patent attorney to draft the specification and handle oppositions and infringement litigation in the court of the Commissioner of Patents. The regime is national — there is no regional patent registry — and South Africa has been a contracting state under the Patent Cooperation Treaty (PCT) since 16 March 1999.

What a Patent Is

A patent is a statutory right granting the patentee the exclusive right to exclude others from making, using, exercising, or disposing of the patented invention in the Republic for a limited term, in exchange for public disclosure of how the invention works. That is the heart of the patent bargain: the inventor publishes enough technical detail that a person skilled in the art can reproduce the invention, in return for the temporary monopoly. Patents protect inventions — products, processes, methods, and apparatus. They do not protect ideas in the abstract, and they do not protect information as such; copyright and trade secrets cover different ground.

What Can (and Cannot) Be Patented

Section 25 of the Patents Act sets the patentability test: an invention is patentable if it is new, involves an inventive step, and is capable of being used or applied in trade, industry, or agriculture.

Excluded by section 25(2)	What it means in practice
Discoveries and scientific theories	Finding a natural phenomenon is not, by itself, patentable — a concrete application must be claimed.
Mathematical methods	The abstract method is out; a technical implementation can still be claimed.
Schemes, rules or methods for mental acts, playing games, or doing business	Abstract business methods are out; technical implementations are not.
Computer programs	Code “as such” is excluded; a software-implemented invention with a technical effect can still be patented.
Presentations of information; literary, dramatic, musical or artistic works; other aesthetic creations	Copyright territory, not patent territory.

Section 25(3) is the gateway: the exclusions apply “only to the extent to which a patent or an application for a patent relates to that thing as such,” so what matters is the framing of the claim. Section 25(4) bars patents for inventions whose exploitation would be generally expected to encourage offensive or immoral behaviour, and for any variety of animal or plant or any essentially biological process (a micro-biological process or its product being the carve-out). Section 25(11) excludes methods of treatment of the human or animal body by surgery or therapy, and diagnostic methods, but section 25(12) preserves patentability for the substance or composition itself. South Africa is a non-examining, depository system — there is no substantive pre-grant examination of patentability, no prior art search, and no pre-grant opposition. The CIPC checks formalities only, and the only real test of validity comes after grant, in revocation proceedings.

The Statutory Framework and the CIPC

The Patents Act 57 of 1978, read with the Patent Regulations, is the controlling statute. It sets the patentability test, defines who may apply, prescribes the application procedure, the term and renewal regime, and the infringement and revocation remedies. South Africa acceded to the Patent Cooperation Treaty on 16 March 1999, so international applicants can designate South Africa in a PCT international application and enter the national phase here, and SA-resident applicants can use the PCT route to defer the cost of foreign filings. The CIPC, which operates from the dti Campus in Pretoria, is the national registry; it took over the patent register from the former South African Patent Office and is the single point of filing for every South African patent. The CIPC’s public register at iponline.cipc.co.za is where to search existing patents and check the status of a pending application.

Who Is Entitled to Be Named as the Inventor

Under section 27(1), an application for a patent may be made by the inventor, by any other person acquiring from the inventor the right to apply, or by both jointly. The right to a patent belongs in the first instance to the actual deviser of the invention; it may be assigned in writing, and the assignee is the owner. Where an invention is made by an employee in the course of employment, the position is governed by the employment contract; absent a contrary agreement, the employee is the inventor but may be required to assign the patent to the employer. Disputes as to entitlement can be referred to the commissioner of patents under section 28. The application must name the true inventor — misstating inventorship is a ground on which a granted patent can later be revoked.

The Patent Process Step by Step

1. Decide on the route. Direct national filing (provisional followed by complete, or direct complete) or PCT international application entering the SA national phase.
2. File a provisional application if the invention is not yet finalised. This establishes a priority date and gives 12 months to file the complete application; a provisional does not require claims.
3. File a complete application within 12 months of the provisional priority date (or directly, without a provisional). The complete application contains the specification (description, claims, drawings if any), the abstract, and the formal request, lodged on the prescribed form and on payment of the prescribed fee.
4. Acceptance by the CIPC. Once in order, the CIPC accepts it and publishes the acceptance in the Patent Journal. If not published within the prescribed period, the application lapses — section 40 sets the base limit at 18 months, extendable on good cause shown.
5. Grant and sealing. Under section 44, as soon as practicable after publication, the patent is granted and sealed, with sealing deemed to have been effected on the date of publication.
6. Renew from before the third anniversary. Annual renewal fees fall due from before the expiration of the third year. A missed renewal renders the patent liable to lapse, but a six-month grace period is available on payment of a late fee. A lapsed patent may be restored under section 47 within the prescribed period, on showing the omission was unintentional.

The claims of the complete application define the scope of the monopoly and must be clear, concise, and supported by the description. This is the part of the patent most often attacked in revocation proceedings.

The 20-Year Term, Renewal Regime, and What It Costs

Under section 46(1), the duration of a South African patent is 20 years from the date of application, subject to payment of the prescribed renewal fees, which fall due annually from before the third anniversary of the effective filing date. There is no provision for patent term extension in respect of regulatory delays, so the 20-year term runs from the effective filing date without adjustment for time spent in clinical trials or regulatory approval. A missed renewal renders the patent liable to lapse, but the registrar may extend the period for payment for up to six months on payment of an additional fee (section 46(2)). A lapsed patent may be restored under section 47 within the prescribed period, on showing the omission was unintentional.

Patent costs break into two distinct categories: official fees to the CIPC (filing, acceptance, sealing, and each annual renewal), which are set in the Patent Regulations and are modest by international comparison — the application fee on the standard form is R590 at the last published CIPC schedule; and patent attorney fees, which depend on the complexity of the invention, the number of claims, the length of the specification, the technical field, and whether opposition or litigation is involved. A straightforward application without opposition typically takes 18 to 36 months from filing to grant, and typically runs into the lower five figures in rand at attorney-fee level through to grant. Attorney fees are quoted per file after review.

What You Can (and Cannot) Do With a Granted Patent

Section 45(1) gives the patentee the right to exclude other persons from making, using, exercising, or disposing of the invention in the Republic, for the duration of the patent. Beyond that core right, three things matter in practice: the patentee may license others to use the invention on terms agreed between the parties (exclusive licences should be recorded with the CIPC to bind third parties); the patent may be assigned in writing (assignments should be recorded with the CIPC to be effective against third parties); and granting a patent does not give the patentee the right to use the invention if doing so would infringe another’s prior patent — the so-called freedom-to-operate problem.

Patent Infringement and What Counts

Direct infringement is making, using, exercising, or disposing of the patented invention without the patentee’s consent. The Patents Amendment Act 17 of 2022 extended the infringing acts in respect of a product obtained directly by a patented process, so that “offering to dispose of” and importation also fall within the infringing acts in that specific context. Infringement is actionable in the court of the Commissioner of Patents (the forum designated under section 8, sitting in Pretoria within the Gauteng Division), and remedies under section 65 include an interdict, delivery-up of infringing goods, and damages (or, in the commissioner’s discretion, an account of profits or reasonable royalty), plus costs. Section 44(4) imposes a nine-month bar on infringement proceedings from the date of sealing, although the commissioner may grant leave earlier on good cause shown. Infringement proceedings are typically run alongside a counterclaim for revocation, since the alleged infringer’s first move is almost always to challenge validity.

Revocation of a Granted Patent

Because South Africa is a non-examining system, the validity of a granted patent is not tested before grant. Once granted, the patent can be challenged on the grounds listed in section 61: wrongful claim to inventorship or ownership, fraud on the applicant or commissioner, the invention not being patentable under section 25, insufficiency in the description or failure to disclose the best method, claims that are not clear or not fairly based on the matter disclosed, a material false statement in the declaration, an application that should have been refused under section 36, or non-compliance with the section 32(6) deposit requirements for microbiological processes. Revocation may be sought in response to an infringement claim (as a counterclaim or defence) or as a standalone application, and is the principal way in which the validity of a South African patent is actually tested.

The PCT International Route

The Patent Cooperation Treaty, administered by WIPO, lets a single international application be filed that designates multiple contracting states. A PCT international application does not itself grant a patent — it preserves priority and gives the applicant time (typically 30 or 31 months from the priority date) to decide which national phases to enter, based on the commercial case for protection in each country. For SA applicants seeking foreign protection, the PCT route defers the heavy cost of multiple national filings and translations; for foreign applicants seeking SA protection, designating South Africa in the PCT and entering the SA national phase is the standard route, and the application is then processed under the Patents Act as a national application. The CIPC acts as a PCT receiving office for SA-resident applicants.

Why You Typically Need a Patent Attorney

Patent prosecution is procedurally and technically specialised, and the CIPC’s requirements on form, sequence, and the contents of the specification are strictly applied. A registered patent attorney knows how to draft claims that are broad enough to deter competitors but narrow enough to survive the validity challenges that come once a granted patent is contested, and most hold a science or engineering degree in addition to their legal qualification. Oppositions and infringement litigation run in the court of the Commissioner of Patents and require the procedural discipline of a litigator. In South Africa, the term “patent attorney” typically refers to a registered patent practitioner who may or may not also be an admitted attorney — those who are admitted can litigate in their own right; those who are not must instruct an admitted attorney for contentious matters. For a searcher who has worked through this framework and now wants to instruct a practitioner, Burger Huyser Attorneys’ intellectual property team is set up to take those instructions through its Linden head office (49 First Avenue, Linden, Randburg, 011 888 0246), with patent prosecution run under specialist consultant Stefaans Gerber and admitted-attorney litigation support available across the firm’s Gauteng branches.

Frequently Asked Questions

How long does a patent last in South Africa?

A South African patent lasts 20 years from the effective filing date (the priority date where priority is claimed). Annual renewal fees are payable from the third anniversary onwards. A lapsed patent can be restored within the prescribed period on application to the CIPC, subject to the requirements of the Patents Act and the regulations.

Do I need to have a working invention before I file a patent?

No. South Africa allows a provisional application to be filed before the invention is finalised, as long as the provisional specification discloses the invention sufficiently to establish the priority date. The complete application, with full claims, must then be filed within 12 months of the provisional.

Can a software invention be patented in South Africa?

A computer program “as such” is excluded from patentability by the Patents Act, but a software-implemented invention that produces a technical effect or solves a technical problem can still be patented if claimed as a technical invention. The “as such” wording matters — it is the framing of the claim that determines whether the exclusion applies.

What is the difference between filing a provisional and a complete patent application?

A provisional application establishes a priority date and gives the applicant 12 months to file the complete application. A provisional does not require claims and does not need to be in final form. A complete application is the substantive filing — it contains the description, claims, and abstract, and is the application that is examined for formal compliance and, if accepted, granted as a patent.

How much does it cost to patent in South Africa?

Official fees are set out in the Patent Regulations and are payable to the CIPC at filing, acceptance, sealing, and each renewal. The basic application fee is set in the regulations (R590 for an application on the standard CIPC form at the last published schedule). Attorney fees depend on the complexity of the invention, the number of claims, and the length of the specification. A straightforward filing through to grant, without opposition, typically runs into the lower five figures in rand at attorney-fee level, with renewal fees adding modest annual cost from year three onwards.

What happens if someone infringes my patent?

Patent infringement is actionable in the court of the Commissioner of Patents. Remedies include an interdict restraining further infringement, delivery-up of infringing goods, and damages (or, in the commissioner’s discretion, an account of profits or reasonable royalty). Infringement proceedings are commonly run alongside a counterclaim for revocation of the patent on validity grounds.

Can I file a patent internationally through the South African system?

The PCT route starts with an international application filed with a receiving office (often the CIPC for SA-resident applicants, or WIPO directly), which can designate multiple contracting states including South Africa. The international application buys time (typically 30 or 31 months from the priority date, depending on the route) to decide which national phases to enter. To get a granted patent in South Africa via this route, the applicant still has to enter the SA national phase and have the application processed under the Patents Act 57 of 1978.
