Patent Requirements in South Africa: What You Need to Know

Patents in South Africa are granted under the Patents Act 57 of 1978 by the Companies and Intellectual Property Commission (CIPC) and protect inventions that are new, involve an inventive step (not obvious to a person skilled in the art), and are capable of being used in trade, industry, or agriculture. An application consists of a petition, a description (with a provisional specification option followed by a complete specification), one or more claims, an abstract, and drawings where needed, and is filed at the CIPC in Pretoria. South Africa operates a deferred-examination system — the application must be accepted first and examination must be requested within six months of the complete specification’s filing date, with extensions available — and a granted patent runs for 20 years from that filing date, subject to annual renewal fees from year three onwards.

The Legal Framework: Patents Act 57 of 1978

The Patents Act 57 of 1978 is the controlling statute, and the Patents Regulations 1978 set out the formal requirements for every application. The Act and the Regulations are read together — the Act sets the substantive law, while the Regulations prescribe the form, content, and procedural steps. South Africa is a member of the Paris Convention and the Patent Cooperation Treaty (PCT), so foreign priority dates and PCT national-phase applications are recognised in the same way as domestic filings. Patents are territorial: a South African patent only confers rights within South Africa, and foreign filing remains a separate step in every other jurisdiction where protection is sought.

The CIPC maintains the official patent register and records all assignments, licences, and renewals. Every procedural step — the formalities check, advertisement in the Patents Journal, examination, grant, and renewal — runs through the CIPC’s national office in Pretoria. There is no provincial patent office and no regional procedure; the Pretoria filing point is the same for inventors in Johannesburg, Cape Town, Durban, or anywhere else in the country. Where the Act refers to a “person skilled in the art,” that figure is a hypothetical technical reader of the patent, not a CIPC official — the test is what such a reader would deduce from the state of the art as a whole.

The Three Patentability Requirements (Section 25 of the Act)

The substantive test for patentability is set out in section 25 of the Patents Act and consists of three cumulative requirements:

1. Novelty — the invention must not form part of the state of the art anywhere in the world before the priority date. Prior public use, publication, or sale anywhere destroys novelty, regardless of where it occurred.
2. Inventive step — the invention must not be obvious to a person skilled in the relevant art, having regard to the state of the art. This is the test that distinguishes a patentable invention from a routine development.
3. Capability of use in trade, industry, or agriculture — the invention must have a practical utility, and must not be purely abstract or speculative.

A failure on any one of these three grounds is enough to refuse an application or invalidate a granted patent, so the three must be considered together from the earliest drafting stage. A claim that is novel but obvious to a skilled reader fails on the second ground; a claim that is novel and non-obvious but has no practical application fails on the third.

What Is Not Patentable (Section 25 Exclusions)

Section 25 also lists categories that are excluded from patentability regardless of novelty or inventive step, because the subject matter is treated as outside the proper scope of patent protection:

• discoveries, scientific theories, mathematical methods, schemes, rules, or methods for performing mental acts
• methods of doing business or pure computer programs “as such”
• presentations of information
• methods of treatment of humans or animals (other than products used in such methods, which remain patentable)
• inventions the publication or exploitation of which would be contrary to public order or morality
• plant or animal varieties, which are protected separately under the Plant Breeders’ Rights Act

Anything new but lacking an inventive step falls outside patentability on the second ground (no inventive step), not on the exclusion list, so it is helpful to keep the two failure modes separate when reviewing an invention. A computer-implemented invention that is excluded as a program “as such” can sometimes be reframed by drafting claims directed at a technical effect the software produces, but only where that effect goes beyond the normal interactions between software and hardware.

Who May Apply (Right to a Patent)

The inventor is the default applicant under section 27 of the Act. An employer is entitled to the patent where the invention was made in the course of employment under a contract requiring inventive activity, unless the agreement says otherwise. An assignee or successor in title may apply, supported by a deed of assignment at filing. Joint inventors apply jointly, and the CIPC records each co-applicant on the patent register.

Where the right to a patent is contested — for example, between an inventor and a former employer — the dispute is resolved before grant, and the eventual proprietor is the party whose name is recorded on the register. Recording the assignment at the CIPC is what gives the assignee the ability to enforce in their own name, and an unrecorded assignment is a common source of enforcement problems later.

The Application Itself: What You File (Section 30 and the Regulations)

Section 30 of the Act and the Patents Regulations together prescribe what an application must contain. The table below sets out each component and when it is required.

Component	What it is	Required?
Petition	Formal request naming the applicant and invention	Always
Provisional specification	Placeholder description establishing a priority date; less detail required	Optional — common when the invention is not yet complete
Complete specification	Full description enabling a person skilled in the art to perform the invention	Always required before acceptance
Claims	Define the legal scope of the monopoly sought	Always
Abstract	Short technical summary for search purposes	Always
Drawings	Where necessary to understand the invention	Conditional
Deed of assignment	Where the applicant is not the inventor	Conditional
Power of attorney	If filed through an agent	Conditional when an attorney files

The complete specification is the document that ultimately defines the 20-year term, so its filing date is the anchor point for both the priority claim and the renewal cycle. A provisional specification is filed first only when the inventor wants to lock in an early priority date while the invention is still being refined; once filed, the applicant has 12 months to file the complete specification.

The Filing Process, Step by Step

1. Decide whether to file a provisional first (to lock in priority while the invention is refined) or to file a complete specification directly.
2. Lodge the application at the CIPC in Pretoria — paper filing, or electronic filing via the CIPC online portal.
3. CIPC formalities check — verification that the application meets minimum formal requirements.
4. Publication in the Patents Journal — accepted applications are advertised for opposition purposes.
5. Request examination — must be filed within six months of the complete specification filing date. Extensions of three months are available on payment of a fee.
6. Substantive examination by a CIPC examiner against the section 25 requirements.
7. Acceptance and grant, or refusal with a right to respond and appeal.
8. Annual renewal fees from the third anniversary of the complete specification filing date.

Filing at the CIPC in Pretoria

The CIPC’s national office in Pretoria is the single filing point for South African patent applications. The CIPC administers the Patents Register, receives applications, conducts the formalities check, and routes applications to examiners for substantive examination once examination is requested. The Patents Journal, the official gazette in which accepted applications and granted patents are advertised, is published by the CIPC and is the public record against which oppositions are lodged.

The patent bar is anchored by the South African Institute of Intellectual Property Law (SAIIPL), the recognised professional body for South African patent attorneys admitted under the Patents Act; practitioners must be registered with the CIPC to act on behalf of applicants. Burger Huyser Attorneys’ intellectual property work is run through specialist consultant Stefaans Gerber, who fields patent and trademark matters in coordination with the firm’s head office in Linden, Randburg (49 First Avenue, Linden, Randburg, 2194, 011 888 0246). The firm’s geographic reach across Gauteng does not change the filing venue, which remains the CIPC in Pretoria regardless of where the inventor is based.

Term, Renewal, and Lapse

A granted patent runs for 20 years from the complete specification filing date. Renewal fees fall due annually from year three; failure to pay within the six-month grace period results in lapse of the patent. A lapsed patent may be restored by application within 12 months of lapse on the prescribed grounds (unintentional or unavoidable non-payment). Restoration is recorded on the register and advertised in the Patents Journal, which puts the public on notice that the patent is back in force. Restoration is not guaranteed — the Commissioner of Patents must be satisfied that the non-payment was unintentional or unavoidable — so paying on time is the safer route.

Procedural Tools: PCT, Paris Priority, and Oppositions

South Africa is a PCT contracting state, so an international PCT application can enter the SA national phase within the prescribed 30/31-month window from the priority date. The Paris Convention priority right applies in the standard 12-month form, allowing applicants to claim the filing date of an earlier foreign application. Third parties can oppose the grant of a pending application based on prior art or other statutory grounds before acceptance, and a granted patent may be challenged by application to the Court in post-grant revocation proceedings. These tools shape the strategy when an applicant is weighing whether to file first in South Africa, treat the local filing as a national-phase entry, or play a defensive game against a competitor’s application.

Working the Patent and Compulsory Licences

There is no formal “working” or local manufacture requirement for the patent to remain valid. Compulsory licences may be granted by the Commissioner of Patents on specific statutory grounds, including where the patented invention is not being worked or is being worked unreasonably. Government use rights apply in defined circumstances set out in the Act. For most applicants, the practical effect is that an unused patent does not lapse automatically — but a competitor may seek a compulsory licence if the invention is not being brought to market on reasonable terms.

Common Mistakes That Cause Applications to Fail

• Disclosing the invention publicly before filing — destroys novelty and cannot be cured, with narrow exceptions for prior display at certain officially recognised exhibitions.
• Drafting claims too narrowly or too broadly — claims that are too broad fail obviousness; claims that are too narrow are easy to design around.
• Filing an inadequate description — failure to enable a person skilled in the art to perform the invention is a ground for refusal and revocation.
• Missing the examination request deadline — failure to request examination within six months of the complete specification filing date (or any obtained extension) results in deemed abandonment.
• Forgetting renewal fees — lapse after the grace period requires restoration, which is not guaranteed.
• Not recording assignments — failure to record an assignment at the CIPC leaves the register showing the wrong proprietor and can complicate enforcement.

For a prospective applicant, the practical lesson is that the requirements are not just about the merits of the invention — the procedural steps and the recording of title matter just as much. Engaging a patent attorney from the outset is the most reliable way to avoid these pitfalls, because the formalities check, drafting conventions, and renewal cycle each carry their own deadlines and own failure modes.

Frequently Asked Questions

How long does a South African patent last?

A granted South African patent lasts 20 years from the complete specification filing date, provided annual renewal fees are paid from year three onwards (with a six-month grace period, after which the patent lapses).

What are the three basic requirements to get a patent in South Africa?

Under section 25 of the Patents Act 57 of 1978, an invention must be new (not part of the state of the art), involve an inventive step (not obvious to a person skilled in the art), and be capable of being used in trade, industry, or agriculture.

Can software be patented in South Africa?

Not as such — section 25 excludes computer programs “as such” from patentability. Software that produces a technical effect beyond the normal interactions between software and hardware, or that solves a technical problem, may be patentable; pure business-method software is not.

Do I have to file my patent in South Africa?

A South African patent only confers rights in South Africa. If you want protection in other countries, you must file separately (or via the PCT route) in each jurisdiction — there is no international patent.

Do I need a patent attorney?

You may file personally, but the application must meet statutory formality and substantive requirements under the Patents Act and Regulations, and a patent attorney registered with SAIIPL is required for examination preparation and opposition work in practice. Most applicants use a patent attorney from the outset to avoid formality refusals and to draft claims with the right scope.

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

A provisional application establishes an early priority date with a basic description and is valid for 12 months; a complete application follows within 12 months with the full description, claims, and abstract, and forms the basis for the 20-year term. The provisional is never examined or granted.

How much does it cost to get a patent in South Africa?

Official CIPC fees cover filing, publication, examination, and renewal. Professional fees depend on complexity — a simple mechanical invention through to grant is materially cheaper than a software-related, biotech, or chemical invention requiring detailed drafting and response to examiner’s objections. Burger Huyser Attorneys confirms cost after the initial IP intake.
