What Are the 5 Requirements of a Patent in South African Law?

A South African patent is granted only when the invention meets five requirements set out in the Patents Act, 1978 (Act 57 of 1978): (1) novelty, meaning the invention must not have been disclosed anywhere in the world before the priority date; (2) inventive step, meaning it must not be obvious to a person skilled in the relevant art; (3) industrial applicability, meaning it must be capable of being used or made in trade or industry; (4) patentable subject matter, meaning it cannot fall within the categories excluded by section 25(2) or section 25(4); and (5) an enabling specification, meaning the patent application must describe the invention clearly and completely enough for a skilled person to perform it. Applications are filed with the Companies and Intellectual Property Commission (CIPC), which acts as the registrar of patents under the Act, through its online portal at iponline.cipc.co.za.

Where Patent Law Comes From in South Africa

The Patents Act, 1978 (Act 57 of 1978) is the controlling statute. Section 25 sets out the substantive patentability test — novelty, inventive step, and industrial applicability — and the exclusions for non-patentable subject matter, while section 32 sets out what the patent specification must contain.

The Patent Regulations, 1978 sit underneath the Act and prescribe the procedural layer: the official forms, the prescribed fees, the form and content of the specification, and the renewal timetable.

The registrar of patents sits at the Companies and Intellectual Property Commission (CIPC), an agency of the Department of Trade, Industry and Competition (the dtic). All new applications, renewals, and recordals are processed through CIPC’s online portal at iponline.cipc.co.za, which is the only operational entry point. There is no provincial or city-level filing venue — a searcher who mistakenly thinks patents are filed at a magistrate’s court or provincial consumer-protection office will be sent back to CIPC, and the same applies to the dtic, which oversees CIPC but does not itself register patents.

South Africa is a contracting state of the Patent Cooperation Treaty (PCT), having become bound on 16 March 1999. An applicant can therefore enter South Africa either by direct filing at CIPC or via the PCT national-phase route, claiming conventional priority from an earlier foreign filing where relevant.

The Five Requirements at a Glance

Requirement	Statutory Basis	What It Tests	Common Reason for Failing
Novelty	Section 25(1)	Was it new at the priority date?	Prior publication, public use, or sale anywhere in the world
Inventive step	Section 25(2)	Would a skilled person find it obvious?	Combining known elements in an obvious way
Industrial applicability	Section 25(3)	Can it be used in trade or industry?	Methods of treatment, purely abstract results
Patentable subject matter	Section 25(2), 25(4)	Is it a patent-eligible type of invention?	Pure software, business methods, discoveries
Enabling specification	Section 32	Is the disclosure sufficient?	Vague description, claims broader than the description supports

Requirement 1: Novelty

Section 25(1) requires that the invention be new at the priority date of the application. Novelty is tested against the state of the art worldwide — South Africa follows an absolute novelty standard, not the older “local novelty” approach, so prior use anywhere in the world counts.

Any disclosure before the priority date can destroy novelty:

• A published academic paper, journal article, or conference proceeding;
• A prior public use of the invention (including testing, demonstration, or sale);
• A patent granted anywhere in the world on the same invention;
• Any other disclosure that put the invention in the public domain.

Because the standard is absolute, inventors who have shown a working prototype at a trade fair, presented at a conference, or offered the product for sale before filing must treat those disclosures as potential novelty-killers. A provisional specification (discussed under Requirement 5 below) is the usual tool for locking in a priority date while the rest of the application is being finalised.

Requirement 2: Inventive Step

Section 25(2) requires that the invention not be obvious to a person skilled in the art, having regard to the state of the art at the priority date. The notional “person skilled in the art” is the standard the law applies — an ordinary practitioner in the relevant technical field, not a layperson.

Two patterns frequently fail this requirement, even where the result was never previously published:

• Combining known elements in an obvious way — taking two existing devices or processes and putting them together where a skilled person would have done so without inventive effort;
• Applying a well-known technique in the obvious direction — using a standard tool to solve a problem that the tool was plainly suited for.

The “skilled person” is hypothetical — the law does not require evidence of what a real individual would have done; the test is applied by the court or the Commissioner of Patents on the basis of the documentary record. Inventive step is therefore a paper exercise conducted against the prior art cited by the parties.

Requirement 3: Industrial Applicability

Section 25(3) requires that the invention be capable of being made or used in any kind of industry or trade. “Industry” is read broadly under the Act and includes agriculture, manufacturing, and services — anything that produces a useful practical effect.

Categories that can fail this requirement depending on how they are framed include:

• Purely aesthetic creations (a feature whose only effect is visual appeal is not “useful” in the industrial sense);
• Methods of treatment of humans or animals (other than products used in such treatment);
• Schemes, rules, or mental acts that do not produce a tangible industrial effect.

Where the claimed invention produces a concrete, repeatable technical effect — for example, a chemical compound that can be manufactured, a machine that can be built, or a process that yields a physical product — industrial applicability is usually straightforward to satisfy.

Requirement 4: Patentable Subject Matter

Sections 25(2) and 25(4) of the Patents Act exclude certain categories from patentability. The exclusions are:

• Discoveries, scientific theories, and mathematical methods;
• Schemes, rules, or methods for performing mental acts or playing games;
• Methods of doing business;
• Computer programs as such;
• Presentations of information;
• Matter that would encourage offensive or immoral behaviour, or that is contrary to public order.

The exclusions are narrower than they look. The phrase “as such” is doing real work: a practical technical application of an excluded category can still be patentable. A computer-implemented invention that produces a technical effect beyond the running of the program itself — for example, controlling an industrial process, improving the functioning of hardware, or producing a measurable physical outcome — can be claimed in those technical terms and is generally accepted at CIPC. The same logic applies to a “business method” that is implemented as a concrete technical system.

This requirement often overlaps with industrial applicability and inventive step, but it remains a separate legal hurdle: even an inventive and industrially applicable invention is unpatentable if it falls squarely within an excluded category.

Requirement 5: Enabling Specification

Section 32 requires the patent specification to describe the invention in a manner that is clear and complete enough for a person skilled in the art to perform or reproduce it. The specification has two parts:

1. The description — background, summary, and a detailed embodiment that puts the invention in context and shows how to make it.
2. The claims — the legally defined scope of the monopoly sought. Claims are the most carefully drafted part of the application because they determine what the patent actually protects and what competitors can continue to do.

Two practical points follow. First, claims that are broader than the description supports will fail the disclosure requirement — if the description only teaches one way of doing it, the claims cannot sweep in alternatives the description never discloses. Second, applicants commonly file a provisional specification first to lock in a priority date while the technical detail and claims are finalised; the complete specification must then follow within 12 months. A provisional does not require claims, but it does require enough disclosure to establish the priority date.

Who Owns the Invention and Who Can File

Section 23 of the Patents Act provides that the right to a patent vests in the inventor. Where the inventor was employed to invent, the right vests in the employer — the employment contract, not inventorship, controls ownership in that case. Joint inventors share the right unless they agree otherwise.

The application is filed in the inventor’s name (or the employer’s name where the employment contract so provides), signed and witnessed, and lodged with the registrar at CIPC. A foreign applicant must use a registered South African patent attorney as address for service — direct filing by an overseas applicant is not permitted in practice, and the attorney’s details go on the form as the channel for official correspondence.

What Happens at CIPC After Filing

South Africa operates a registration system, not an examination system in the sense used by the USPTO or the EPO. CIPC conducts a formal examination only — the registrar checks the forms, fees, signatures, and specification layout, but does not investigate whether the invention is genuinely novel or inventive. Patents proceed to grant once the formalities are in order.

Substantive validity — novelty, inventive step, industrial applicability, patentable subject matter, and sufficiency of disclosure — is tested only on challenge. Any interested party may bring opposition or seek revocation on substantive grounds before the Commissioner of Patents, a court constituted under the Act and presided over by a person appointed by the Minister, sitting in Pretoria rather than at CIPC’s registration desk.

The lifecycle numbers for a granted South African patent are:

• Term: 20 years from the application date.
• Renewal: annual renewal fees from year 3 onwards (a renewal falls due on the anniversary of the application date).
• Lapse: a patent lapses if a renewal fee is unpaid. Restoring a lapsed patent requires a formal application and restoration fee under the Regulations, and is not granted as of right.

Because novelty and inventive step are not examined up front, a granted South African patent is not a clean bill of health for the underlying invention — competitors or other interested parties can put the patent to a substantive test after grant, and the same grounds are available to defend against infringement.

Burger Huyser Attorneys handles intellectual-property work through specialist consultant Stefaans Gerber, whose practice covers patent and trademark prosecution, IP licensing, and assignment. Patent drafting and prosecution are run out of the firm’s head office in Linden, Randburg (49 First Avenue, 011 888 0246) and are not restricted by branch, because the Patents Act, 1978 applies uniformly across South Africa and CIPC is the single national registrar. If you are weighing whether your invention meets the patentability requirements above, the firm can refer you to the right patent attorney for a novelty and inventive-step opinion before any filing is lodged.

Frequently Asked Questions

Does South Africa examine patents for novelty and inventive step?

No. CIPC only examines patents formally (correct forms, fees, signatures, and specification layout). The novelty, inventive step, and industrial applicability requirements are not examined substantively at registration; they can be challenged by any interested party after grant before the Commissioner of Patents. This makes the South African system a “registration system” in practice, with substantive validity tested only on challenge.

Can you patent a computer program in South Africa?

Not as such. Section 25 excludes computer programs from patentability in their pure form. A computer-implemented invention that produces a technical effect beyond the running of the program itself — for example, controlling an industrial process or improving the functioning of hardware — can still be patentable when claimed in those terms.

How long does a South African patent last?

A maximum of 20 years from the application date, conditional on paying annual renewal fees from year 3 onwards. If renewal fees are not paid on time, the patent lapses and can only be restored by a formal application under the Regulations.

Can a foreign applicant file directly at CIPC?

In practice, no — a foreign applicant is required to use a registered South African patent attorney as address for service. The attorney files the application at CIPC on the foreign applicant’s behalf and receives official correspondence.

What is the difference between a provisional and complete specification?

A provisional specification establishes a priority date but does not need to include claims or a full description. A complete specification must follow within 12 months and must include the full description and claims. Many applicants file a provisional first to lock in the priority date while finalising the technical detail.
