A Practical Guide to Patent Application and Grant in South Africa

You have solved the problem. The prototype runs, the formulation is stable, the process gives a better yield than anything on the market. The natural next step is to show someone: a distributor, a customer who has been waiting, an investor who wants to see it before committing. That instinct is sound in every respect but one.

In South Africa, novelty is absolute. Section 25 of the Patents Act 57 of 1978 defines the state of the art as everything made available to the public — anywhere in the world, in any language, by any means — before the priority date of your claim. A conversation at a trade show in Johannesburg, a product page that went live for an afternoon, a pitch deck emailed without a confidentiality agreement: any of these can put your own invention into the prior art and defeat the patent you have not yet filed.

There is no general grace period. Sections 26 and 27 excuse a narrow set of disclosures — matter obtained from you without your knowledge or consent, working in the Republic by way of reasonable technical trial or experiment, and display at an officially recognised exhibition — but these are defences to invalidity with strict conditions and short windows, not a safety net. They are worth knowing about. They are not worth relying on.

The order of operations is the whole game: file first, then talk. Everything else in this guide is detail.

What a South African patent actually gives you

A patent is a monopoly of twenty years, running from the filing date of the complete application, in exchange for a full public disclosure of how to work the invention. It is a right to exclude others from making, using, exercising, disposing of or importing the invention in South Africa — not a right to practise your own invention, and not a right that reaches beyond our borders. Patents are territorial. Protection in Germany or the United States requires applications in Germany or the United States.

To be patentable, an invention must be new, involve an inventive step, and be capable of being used or applied in trade, industry or agriculture. Section 25(2) excludes certain things from being inventions at all: discoveries, scientific theories, mathematical methods, aesthetic creations, schemes and methods for performing mental acts, playing games or doing business, computer programs, and the presentation of information. Critically, section 25(3) limits those exclusions to the subject matter as such. A computer-implemented invention that produces a technical effect is not automatically excluded — how it is framed and claimed does real work. Methods of treatment of the human or animal body are separately excluded under section 25(11), though substances for use in such methods can be claimed.

One feature of our system deserves emphasis early, because it shapes everything downstream. South Africa is a non-examining, depository jurisdiction. CIPC examines patent applications for compliance with formalities. It does not search the prior art and does not assess novelty or inventive step before granting. A South African patent is granted on the strength of your own paperwork.

That makes grant easy and validity uncertain. The first genuine test of whether your patent is any good usually comes in revocation or infringement proceedings, when it is expensive and the stakes are real. The practical consequence is that the quality of the drafting — the search you did or did not commission, the claim scope you chose, the fallback positions you built in — is not policed by anyone but you and your attorney. A granted South African patent proves that the fees were paid. It does not prove that the invention was patentable.

Step one: the provisional application

Almost every South African filing programme starts with a provisional application. Under section 30(1) it must be accompanied by a specification that describes the invention, but it needs no claims, and it is never examined or published. Its single job is to fix a priority date.

That date is the reference point against which novelty and inventive step are later judged, in South Africa and — through the Paris Convention — in every other member country for the following twelve months. Filing a provisional buys you a year in which you can talk to customers, run trials, seek funding and refine the commercial case, with the prior art frozen as at your filing date.

Two cautions. First, a provisional confers no enforceable rights. You may mark the product “patent pending”, but you cannot sue anyone on a provisional. Second, and more often fatal, your priority is only as good as your disclosure. A thin provisional that gestures at a concept without enabling it will not support the claims you eventually want. If the complete application adds matter that was not disclosed in the provisional, that matter takes the later date — and your own intervening disclosures may then be citable against it. A provisional is a cheap filing, not a cheap draft.

Step two: the twelve-month decision

Twelve months after the provisional, one of three things must happen:

• Abandon. The provisional lapses and the priority date is lost. This is a perfectly rational outcome where the market has not materialised, and it is what the year was for.
• File a South African complete application. This is the route to a granted South African patent, and only a South African patent.
• File convention applications directly abroad. Using the Paris Convention priority right, file a complete application straight into each foreign country or region of interest. This is the fastest route to grant in those countries and often the cheapest where only one or two markets matter.
• File an international (PCT) application. This keeps the door open to South Africa and most of the rest of the world, and defers the expensive country-by-country decision by a further eighteen or nineteen months.

The three filing routes are not mutually exclusive. A South African complete application can sit alongside direct convention filings abroad, and many applicants who choose the PCT route later enter the South African national phase from it. What follows sets out each route and the timeline that governs it.

One quirk is worth knowing. For a South African complete application, the twelve-month period can be extended by three months on payment of a fee, giving fifteen months from the provisional. That extension is a creature of our domestic law only. It does not extend the Paris Convention priority year. A PCT or foreign convention application must still be filed within twelve months, full stop. Applicants who assume the extension applies across the board lose foreign rights.

Route one: the South African complete application

The complete specification is the real document: a full enabling disclosure, drawings where they assist, and — the operative part — a set of claims defining the monopoly. Once filed, the application proceeds to formal examination. CIPC checks the forms, the declarations, the assignments and proof of title, the payment of fees, and compliance with the regulations. It does not read the claims against the prior art.

Acceptance typically issues somewhere between nine and eighteen months after filing, depending on how cleanly the formalities are dealt with. If you need more time — commonly because a corresponding foreign application is still being examined and you want to align the claims — acceptance can be delayed on request, for up to eighteen months from filing for a domestic application, with a further three months available on payment of a fee. Beyond that, extension is at the Registrar’s discretion and on good cause shown.

Once the notice of acceptance issues, the applicant must publish the acceptance in the Patent Journal within three months. Publication is what completes the process: the patent is granted, the file becomes open to public inspection, and the monopoly becomes enforceable. Missing the publication deadline without an extension causes the application to lapse — an avoidable and expensive way to lose a case that has already been accepted.

There is no opposition procedure in South Africa, either before or after grant. A third party who believes your patent should not have been granted must apply to the Commissioner of Patents to revoke it. This cuts both ways: nobody can hold up your grant, and nobody has vetted it either.

Renewal fees are payable annually from the third anniversary of the filing date and must be kept up for the full twenty years. A patent that lapses for non-payment can be restored on application, but restoration is discretionary and third parties who began working the invention in the interim may acquire rights. Diarise renewals properly, or have your attorneys do it.

Route two: filing directly under the Paris Convention

If you already know which one or two foreign countries matter and you are confident in that choice, you do not need the PCT at all. The Paris Convention gives you a twelve-month priority right, and you can exercise it by filing a complete application straight into each country or region of interest — a convention complete application at CIPC, a European patent application at the EPO, a non-provisional application at the USPTO, and so on. Each carries the priority date of your South African provisional, provided it is filed within twelve months of it.

This is the direct route, and its appeal is simplicity and speed. There is no international phase and no eighteen-month detour. Each application lands in its destination office straight away and begins its own prosecution on that office’s timetable, which means grant in those countries comes sooner than it would through the PCT. Where the destination is a single major market, the direct route is frequently both faster and cheaper than routing through Geneva.

The direct route asks more of you earlier, and that is its real cost. There are two things to weigh. First, the money. Filing complete applications, engaging local attorneys and paying for translations in several countries all fall due at the twelve-month mark, together. The PCT exists precisely to spread that spend out; the direct route does not. Committing to five countries directly means funding five national filings at month twelve, before you have any independent read on whether the claims will hold.

Second, the missing search. Because there is no PCT phase, there is no International Search Report or Written Opinion to tell you where the prior art sits before you commit. You go into each national examination — in offices that, unlike CIPC, do examine — without that early warning. For a well-searched invention aimed at a known market this is a reasonable trade; for anything speculative or aimed at many countries, the PCT’s search and deferral usually earn their keep.

As a rule of thumb: the direct route suits a small number of certain markets and a strong prior-art position, while the PCT suits breadth, uncertainty, or a need to defer cost. The two are not exclusive — a South African complete application can run alongside direct filings abroad.

Route three: the PCT and national phase

If the invention has export potential — and for most South African applicants of any ambition it does — the twelve-month deadline is where the international decision gets made. Filing separate applications in ten countries at month twelve is possible, and ruinously expensive. The Patent Cooperation Treaty exists to defer that bill.

A single international application, filed within twelve months of the provisional and claiming its priority, has the effect of a filing in every one of the PCT’s contracting states. It does not grant anything. What it buys is time and information.

The search report is the point

Around sixteen months from priority — three months from receipt of the search copy by the International Searching Authority, or nine months from the priority date, whichever is later — the ISA issues an International Search Report and a Written Opinion. The ISR lists the prior art the examiner considers relevant and grades each document by how it bears on your claims. The Written Opinion is a reasoned, non-binding assessment of novelty, inventive step and industrial applicability.

For a South African applicant this is the single most valuable document in the whole process, and the reason the PCT route often makes sense even where only one or two foreign markets matter. Our own office will never tell you whether your claims are patentable. The ISA will, in writing, roughly fourteen months before you have to spend money on national filings. A Written Opinion that cites a close piece of prior art you had not found is unwelcome news arriving at exactly the right time — early enough to narrow the claims, redirect the programme, or stop spending.

At eighteen months from priority, the application is published by WIPO with the search report. From that point the disclosure is public and citable, which is worth planning around commercially.

Chapter II, and the thirty-month cliff

Where the Written Opinion is negative but the position looks recoverable, you can file a demand for international preliminary examination under Chapter II, generally by twenty-two months from priority or three months from transmittal of the ISR and Written Opinion, whichever expires later. This allows claim amendments and argument, and produces an International Preliminary Report on Patentability at around twenty-eight months. It is optional, it does not extend national phase deadlines, and it is most useful where a favourable report will help in offices that give it weight — or where it will materially improve the conversation with a licensee or investor.

National phase entry is the hard deadline. In most countries it falls at thirty months from the earliest priority date; South Africa, the EPO, Australia, India and others allow thirty-one. In South Africa the Registrar has a discretion to extend national phase entry by a further three months on formal request. That discretion is real, but it is not a plan.

National phase entry is also where the costs arrive together: official fees, local attorneys, and translations in each jurisdiction. Two and a half years of deferral is exactly what the PCT is for, but the bill does eventually land, and it lands all at once. Budget for month thirty long before month thirty.

A South African national phase application, once entered, proceeds much as a domestic complete application does — formalities, acceptance, publication of acceptance, grant — with the difference that acceptance may be delayed for up to twelve months from national phase entry, plus a three-month extension, rather than the eighteen months available domestically. The twenty-year term runs from the international filing date, not the national phase entry date.

Choosing between the routes

The honest answer is that the choice is commercial, not legal. A few factors carry most of the weight:

• Where the market is. If the product will only ever be made and sold locally, a South African complete application is the proportionate answer. If your customers, competitors or manufacturers sit abroad, a South African patent alone protects very little.
• How many countries, and how sure you are of them. Where you want protection in only one or two markets and you are confident in the choice, filing directly under the Paris Convention is usually faster to grant and cheaper than the PCT. Where the list is longer, still forming, or genuinely uncertain, the PCT lets you keep every option open on a single filing and decide later.
• Where the manufacturing is. A patent that covers your market but not the country where knock-offs will be made can still be effective, because importation infringes. A patent that covers neither is decorative.
• How certain you are of the prior art. If you have not commissioned a search and the field is crowded, the PCT search report is cheap insurance against spending real money on an invalid claim set. The direct route gives you no such early read.
• Funding rhythm. The direct route brings every country’s costs forward to month twelve. The PCT pushes the largest single spend out to month thirty, which frequently aligns with a funding round or first revenue. That alignment is often the deciding factor in practice.

On acceptance	Publish acceptance in the Patent Journal within 3 months — grant follows publication
Year 3 onward	Annual renewal fees
Year 20	Patent expires

Mistakes we see most often

• Disclosing before filing. Still the most common and the least recoverable. A signed NDA before any substantive discussion costs nothing.
• A provisional that does not enable the invention. The priority date only covers what was actually disclosed.
• Assuming the fifteen-month extension applies abroad. It does not. Foreign and PCT filings are due at twelve months.
• Treating grant as validation. CIPC did not check. Nobody did.
• Missing the Patent Journal publication window after acceptance. An accepted application can still lapse.
• Letting renewals slip. Restoration is possible, discretionary, and worse than not having lapsed.
• Filing before the invention is properly identified. Sometimes the patentable contribution is not the thing you built but the principle underneath it. That is a drafting conversation, and it is best had early.

At Wolmarans and Susan Inc. we work with clients across the full life of a patent — from freedom-to-operate and patentability searching, through provisional and complete drafting, PCT filing and national phase co-ordination, to renewals, oppositions abroad and enforcement here. Our practice spans chemical and formulation inventions, mechanical engineering, and software and machine learning systems, which means the person drafting your specification understands the technology as well as the statute.

If you are approaching a disclosure, a twelve-month deadline, or a national phase decision, we would rather have the conversation early than fix the consequences later. Get in touch to discuss your invention in confidence.
