How to File a Patent in South Africa Step-by-Step

To file a patent in South Africa, an applicant files a provisional application with the Companies and Intellectual Property Commission (CIPC) to fix a priority date, then files a complete application within 12 months setting out the full invention, claims, and drawings, all under the Patents Act 57 of 1978. South Africa historically operates a depository (non-substantive-examination) system, meaning a complete application is accepted largely on formalities once any office objections are met; the CIPC now also offers applicants the option of substantive examination for stronger validity. A granted patent runs for 20 years from the effective filing date, with annual renewal fees required from year three onwards. Provisional applications may be filed by an individual directly with the CIPC, but a registered South African patent attorney must act on the applicant’s behalf for the complete application and any subsequent prosecution.

What the Filing Route Actually Protects

A granted South African patent gives the owner the right to exclude others from making, using, exercising, or disposing of the invention within South Africa for the term of the patent. A patent is territorial — a South African patent protects the invention only in South Africa; protection elsewhere requires separate national filings, or a Patent Cooperation Treaty (PCT) application with national-phase entry in each country of interest. A patent does not, on its own, give the right to make or use the invention — other IP regimes (registered designs, copyright in drawings) and sector-specific regulation (medicines control, mining title) may still apply independently and need to be cleared.

What Can (and Cannot) Be Patented Under the Patents Act

Section 25 of the Patents Act 57 of 1978 sets the substantive test: a patent may be granted for a new invention that involves an inventive step and is capable of being used or applied in trade, industry, or agriculture.

• Novelty — the invention must not form part of the state of the art immediately before the priority or filing date. Public disclosure anywhere in the world before that date can destroy novelty.
• Inventive step — the invention must not be obvious to a person skilled in the relevant art, having regard to the state of the art at the priority date.
• Industrial applicability — the invention must be capable of being made or used in some kind of industry (broadly interpreted to include agriculture).

The Patents Act also expressly excludes: discoveries, scientific theories, mathematical methods, schemes or rules for performing mental acts, playing games, or doing business; methods of treatment of humans or animals by surgery, therapy, or diagnosis (other than products used in such treatment); computer programs “as such”; and presentations of information “as such”. A public-order or morality carve-out excludes inventions whose publication or exploitation would be contrary to public order or morality. Software-related inventions are patentable when claimed as a technical solution to a technical problem, but not when claimed only as a “computer program as such”.

The Two-Step Filing Structure: Provisional Then Complete

A provisional application establishes a priority date with a relatively lightweight disclosure — sufficient if it describes the invention in enough detail to establish what the applicant was in possession of on that date. A provisional is not examined, grants no enforceable rights on its own, and lapses automatically after 12 months unless followed by a complete application. Filing complete directly is permissible — the complete’s filing date then becomes the priority date — but the applicant forfeits the 12-month buffer to refine claims and conduct further prior-art work.

The standard commercial practice is to file provisional first to “lock in” the priority date before going public with a product, talking to investors, or showing the invention at an exhibition, then to file complete within the 12-month window. The Paris Convention priority window runs for 12 months from the earliest filed application: an applicant who first files in another Paris Convention country (including South Africa) can claim that earlier filing date when filing in other Paris Convention countries within the same window.

The South African Filing Process, Step by Step

1. Confirm patentability with a registered patent attorney. The first conversation covers whether the invention meets the novelty, inventive step, and industrial applicability tests, and whether prior art exists that would block grant.
2. Conduct a prior-art search. Search the CIPC register, Espacenet, Google Patents, and non-patent literature to assess novelty before incurring filing cost.
3. File a provisional application. A provisional establishes the priority date. Provisional applications may be filed personally with the CIPC, or through a registered patent attorney.
4. File the complete application within 12 months of the priority date. This sets out the full invention, claims, drawings, and abstract. The priority date from the provisional carries through to the granted patent’s term. A registered South African patent attorney must act on the applicant’s behalf for this step.
5. Formal examination and prosecution. The CIPC checks the application for procedural compliance; any office objections must be addressed through written responses and, where necessary, claim amendments.
6. Substantive examination (optional). Applicants may opt into the CIPC’s substantive examination offering, in which case an examiner searches prior art and assesses novelty and inventive step before acceptance. Electing substantive examination provides a stronger presumption of validity.
7. Acceptance and advertisement. Once accepted, the application is advertised in the Patent Journal, opening a window during which third parties may oppose.
8. Grant and sealing. After acceptance and resolution of any oppositions, the patent is granted and a patent certificate is sealed.
9. Renewal fees from year three. Annual renewals fall due on the third anniversary of the filing date and must be paid each year thereafter to keep the patent in force. Lapsing through non-payment can be restored within a limited window.

The Role of the CIPC

The Companies and Intellectual Property Commission (CIPC), a juristic body within the Department of Trade, Industry and Competition (the dtic), is the South African patents registry and the office that accepts, advertises, and grants patents. The CIPC publishes the Patent Journal and maintains the electronic register of granted patents. All filings, advertisements, and grant records are administered centrally through the CIPC; there is no regional or provincial patents office, and no High Court appearance is required to obtain a granted patent.

South Africa’s Depository System and the Substantive Examination Option

South Africa has historically operated a non-examination (depository) patent system — applications are accepted and granted largely on the basis of formalities rather than substantive patentability, which is unusual internationally. The Patents Amendment Act 20 of 2005 tightened procedural requirements, including the documentation that must be lodged before acceptance. Applicants may now opt into the CIPC’s substantive examination offering — when elected, the examiner searches prior art and assesses novelty and inventive step before acceptance.

For high-value inventions in crowded technology fields, electing substantive examination provides a stronger presumption of validity and makes the patent harder to challenge later. For low-stakes filings or short-lived inventions, the default depository route remains faster and cheaper; the strategic question is whether the cost of substantive examination is justified by the technology’s commercial life.

Patent Term, Renewal Fees, and Lapsing

A granted South African patent runs for 20 years from the effective (priority) date. Annual renewal fees fall due from the third anniversary of the filing date onwards and must be paid each year to keep the patent in force. Late payment is permitted within a six-month grace period after the due date on payment of a prescribed penalty. After the grace period, the patent lapses; restoration is possible only on a formal application to the CIPC showing that the failure to pay was unintentional and that no third-party rights have crystallised in the meantime. Once a patent is off the register and the restoration window has closed, it cannot be revived.

Provisional vs Complete Application: At a Glance

Feature	Provisional application	Complete application
Purpose	Establishes a priority date	Sets out the full invention and is examined for grant

Cost	Lower filing fee	Higher filing fee plus attorney fees for drafting and prosecution

International Protection: Paris Convention and PCT National Phase

South Africa is a party to the Paris Convention — an applicant who first files a regular application in a Paris Convention country (including South Africa) can claim that earlier filing as a priority date when filing in other Paris Convention countries, generally within 12 months. South Africa is also a contracting state to the Patent Cooperation Treaty (PCT) — an applicant can file a single PCT international application designating multiple countries (including South Africa), deferring national-phase entry for up to 31 months from the earliest priority date. To obtain a patent in South Africa via the PCT, the applicant must enter the SA national phase within 31 months of the priority date, instructing a registered SA patent attorney and paying the prescribed national-phase fees. The Paris Convention route is generally simpler and cheaper for an applicant who already has, or intends to have, an SA filing and only needs protection in a handful of other countries; the PCT is useful when the applicant wants deferred national-phase entry across many jurisdictions.

Who Must Act on the Applicant’s Behalf

The Patents Act and the CIPC’s practice require that complete patent applications and any subsequent prosecution be handled by a registered South African patent attorney acting on the applicant’s behalf — individuals and companies cannot lodge complete applications directly with the CIPC without representation. A registered patent attorney is qualified to advise on patentability, draft the specification and claims, respond to office actions, and handle oppositions.

Provisional applications are an exception — the CIPC’s own position, as stated on its Patents information page, is that individuals may file their own provisional patent applications without representation; DIY filing services exist for this purpose, but they cover only the filing step and do not extend to specification drafting, claims, or prosecution. Burger Huyser Attorneys delivers intellectual property work through specialist consultant Stefaans Gerber (Patent & Trademark Attorney), covering patent and trademark prosecution, IP licensing and assignment, and commercial / IP contract drafting.

Common Mistakes That Derail a Filing

• Disclosing the invention publicly before the priority date. Selling, demonstrating, publishing, or posting on social media without a confidentiality regime can destroy novelty — the single most common reason patents fail.
• Filing the provisional with too little technical detail. If the provisional does not enable a person skilled in the art to make the invention, it cannot support the priority claim for later-filed claims.
• Letting the 12-month provisional-to-complete deadline slip. A missed deadline kills the priority date, and a late-filed complete application cannot rely on it.
• Drafting claims too narrowly or too broadly. Narrow claims are easy to design around; broad claims are vulnerable to examiner or opposition objection for lack of support or clarity. Claims should be drafted by a registered patent attorney with relevant technical background.
• Skipping renewal fees and assuming restoration is straightforward. Restoration is discretionary and turns on factual questions about intent and intervening third-party rights.
• Filing complete without instructing a registered patent attorney. Applications filed without representation are not accepted by the CIPC.

Frequently Asked Questions

How long does it take to get a patent granted in South Africa?

From the complete application filing to grant typically takes 12 to 36 months, depending on whether the applicant opts into the CIPC’s substantive examination programme, the examiner’s workload, and whether any office actions need to be overcome. The 12-month provisional-to-complete window is fixed; the time from complete filing to grant is not.

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

Total cost combines CIPC filing fees (set out in the CIPC’s current fee schedule, which is revised periodically), patent attorney fees for drafting and prosecution, and renewal fees from year three onwards. CIPC fees are a relatively small component of the total; attorney fees and 17 years of renewal annuities are the larger line items over a 20-year term. Specific quotes depend on the invention’s technical complexity and the firm’s fee structure.

Can I file a patent myself in South Africa?

Partially. The CIPC’s own position is that individuals may file their own provisional patent applications without representation, and DIY filing services exist for that step. However, the Patents Act and CIPC practice require a registered South African patent attorney to act on the applicant’s behalf for the complete application and any subsequent prosecution — complete applications filed without representation are not accepted by the CIPC.

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

A provisional application establishes a priority date with a lower-cost, less-formal disclosure and gives the applicant 12 months to file the complete application. A complete application contains the full specification, claims, and drawings and is the application that is examined, advertised, and granted. Filing provisional first is standard practice; filing complete directly is possible but forfeits the extra 12 months to refine claims and conduct further prior-art work.

What is the term of a South African patent?

20 years from the effective (priority) date, subject to annual renewal fees from year three onwards. Once a patent lapses for non-payment of renewal fees, restoration is possible only on a formal application showing the non-payment was unintentional and not at all if third-party rights have crystallised in the meantime.

Can I get patent protection in South Africa through the PCT?

Yes — South Africa is a PCT contracting state, and a PCT applicant can designate South Africa and enter the SA national phase within 31 months of the priority date, instructing a registered SA patent attorney and paying the prescribed national-phase fees. For applicants only interested in South Africa, the Paris Convention route via a direct SA filing is usually simpler and cheaper.

What can and cannot be patented in South Africa?

A patent can be granted for a new invention that involves an inventive step and is capable of being used in trade, industry, or agriculture. The Patents Act expressly excludes discoveries, scientific theories, mathematical methods, business or game-playing methods, methods of medical treatment or diagnosis practised on humans or animals, and inventions contrary to morality or public order. Computer programs and presentations of information are excluded “as such” but are patentable when claimed as a technical solution to a technical problem.
