A prior art search Johannesburg litigation counsel can build a revocation case on carries unusual weight, because South Africa never examined the patent in the first place. The Companies and Intellectual Property Commission (CIPC) is a non-examining, depository office: it grants patents once the formalities are in order, without ever testing novelty or inventive step. Nothing on the register was vetted at grant, so the only forum that ever weighs an invention against the prior art is the court — the Court of the Commissioner of Patents in Pretoria. PerspireIP builds invalidity-grade searches for accused infringers and applicants seeking revocation of a granted South African patent from Johannesburg, Gauteng’s commercial heart.
Why a prior art search Johannesburg defendants commission decides the case
South Africa runs a non-examining (depository) patent system. Unlike the USPTO or the EPO, the CIPC does not conduct a substantive search or examination before grant. Once the formal requirements are met, a complete application must be accepted, and a certificate follows. No examiner ever measured the claims against the state of the art. That single fact reshapes the litigation: validity is untested at grant and is only ever decided if and when a patent is challenged in court.
The practical consequence for an accused infringer is stark. There is no prosecution file wrapper full of examiner citations to mine, and no presumption that the office found the invention new. The prior art record simply does not exist until you build it. A rigorous, independent prior art search Johannesburg counsel can put before the court therefore is not corroboration of an examiner’s work — it is the first and only technical scrutiny the patent has ever faced.
- CIPC — grants patents on formalities only; no substantive novelty or inventive-step examination
- Court of the Commissioner of Patents — the sole first-instance forum where validity is actually tested
- Patents Act 57 of 1978, section 61 — the statutory grounds for revoking a granted patent
- Supreme Court of Appeal — hears appeals from the Commissioner, with the Constitutional Court above it
Where a South African patent fight is actually heard
South Africa concentrates all patent litigation in one specialist forum. The Court of the Commissioner of Patents is a court of the Gauteng Division of the High Court, seated in Pretoria, and it has nationwide first-instance jurisdiction over patent infringement and revocation. A matter arising anywhere in the country — a mining-equipment dispute on the Witwatersrand or a fintech assertion in Sandton — is filed and tried there. First-instance matters are decided by a single High Court judge sitting as Commissioner, appointed on an ad hoc basis.
Johannesburg is where the commercial reality of those disputes lives, even though the court sits in neighbouring Pretoria within the same Gauteng province. The city is home to the corporate head offices, the mining houses, the banks and the litigation teams that drive most patent enforcement in the country. Appeals from the Commissioner run to the Supreme Court of Appeal in Bloemfontein, and constitutional questions may reach the Constitutional Court, so an adverse validity finding can travel a long way — another reason to get the prior art right at first instance.
Revocation under section 61: the grounds your art must reach
Any interested person may apply to revoke a South African patent, and the grounds are set out in section 61 of the Patents Act 57 of 1978. The two grounds that turn on prior art are the ones a search is built to feed: that the invention is not new (lacks novelty over the state of the art) and that it is obvious (lacks an inventive step). South African courts have held that each ground of revocation is a separate and independent cause of action, because the essential facts to be proved for each are different.
An accused infringer can raise invalidity in one of two ways. Revocation can be pursued as a standalone application, or it can be brought as a counterclaim in reconvention when the patentee sues for infringement first. In the leading Ascendis Animal Health v Merck matter, the Constitutional Court grappled with whether validity attacked once as a sword (revocation) can be re-run as a shield in a later infringement action — a res judicata trap that makes it essential to marshal your best prior art the first time, not hold references back.
- Lack of novelty — a single prior disclosure that anticipates every element of the claim
- Obviousness (no inventive step) — a combination the skilled person would reach without invention
- Standalone revocation vs counterclaim — attack proactively, or in reconvention once sued
- Res judicata risk — run your full invalidity case once; withheld art may be shut out later
Where Johannesburg’s prior-art fights come from
Johannesburg grew up as a mining city, and mining technology still shapes its patent docket. Gauteng hosts the head offices of global mining groups and a deep supply chain of drilling, ore-processing, materials-handling, ventilation and safety-equipment makers. Much of the decisive prior art in these disputes is old, mechanical and industrial — equipment manuals, engineering standards, trade catalogues, mine-safety publications and long-expired patent families — the kind of literature that a depository office, having never searched, would never have surfaced.
Layered on top of that industrial base is Africa’s largest financial centre. Sandton is home to the Johannesburg Stock Exchange, the continent’s biggest, and to a fast-growing fintech, payments and data-centre cluster running up the Midrand corridor. These disputes turn on software, payments and networking claims, where the anticipating reference is frequently non-patent literature: product documentation, standards, developer records and archived web pages that must be dated to the day. A prior art search Johannesburg counsel relies on has to work both veins — heavy-industry engineering and modern software — because the city’s economy spans both.
Manufacturing and energy round out the picture. Automotive components, industrial machinery, chemicals, and a rapidly expanding renewable-energy and grid sector all generate assertions in Gauteng. For the accused party, the fastest and most durable answer is nearly always a piece of art the patentee’s own filing never disclosed — which, in a country that never examined the patent, is a great deal of art indeed.
A depository grant plus an offshore original: the double search
Many South African patents are national-phase entries from a PCT application or Convention priority claim first filed elsewhere. That gives an invalidity team two things to work with. The foreign counterpart was often examined by the EPO, the USPTO or another searching office, so its file wrapper, cited art and any opposition or reexamination record are a starting map of what the invention was tested against abroad — even though none of that examination binds the South African grant.
But the foreign file is only a starting point. Because CIPC added nothing to it, the South African claims may be broader than anything a foreign examiner allowed, and the priority date that actually governs each claim has to be pinned down independently. We treat the offshore prosecution history as a lead source, then search well beyond it — targeting the exact claim scope on the South African register and the true priority date, not the tidier version that survived examination overseas.
The gap between the two documents is often where the case is won. A claim amended narrowly in Munich or Alexandria to survive an examiner’s objection may sit on the South African register in its original, unamended, broader form, because no examiner here ever asked for the narrowing. Art that was merely close to the amended foreign claim can be squarely anticipatory of the wider South African claim. We chart both versions side by side and flag every place the local claim reaches further than its examined counterpart.
Then we aim the search at exactly those extensions — the parts of the monopoly that have never been tested against the prior art anywhere in the world. In a depository jurisdiction, that untested margin is frequently the widest and most vulnerable part of the whole patent, and it is where a well-targeted invalidity search does the most damage.
The examination reform is coming — but the burden is still on you
CIPC has signalled a move toward substantive search and examination and has been running an Experiential Learning Programme to train patent examiners on real applications. That reform is real, but it is prospective and phased: the vast majority of patents on the register today — and those being asserted in current litigation — were granted without any examination at all. For live disputes, the depository reality still governs, and the prior art burden sits squarely with the challenger.
That makes independent searching decisive rather than optional. Where an accused infringer in the US or Europe can lean on an examiner’s citations as a floor, a defendant in South Africa has no such floor. The court will decide novelty and inventive step on the record the parties put before it, and the party that assembles the more complete, better-dated prior art record controls the outcome. Until substantive examination is fully in force for granted, asserted patents, that party has to be you.
How PerspireIP builds a prior art search Johannesburg case can rely on
Every engagement follows the same disciplined path. We map the asserted claims element by element, fix the priority date that actually governs each one, and search against that date rather than the filing date on the cover. Because nothing was examined at grant, we build the record from scratch: patent families worldwide, the foreign counterpart’s prosecution history where one exists, and the non-patent literature — engineering standards, equipment manuals, product documentation, standards contributions and archived web pages — that a depository office never touched.

Frequently Asked Questions
Does South Africa examine patents before granting them?
No. The CIPC is a non-examining, depository office. It checks that the formal requirements are met and then grants the patent — it never conducts a substantive search or tests novelty and inventive step. That means no examiner ever measured the claims against the prior art, there is no citation record to inherit, and validity is only ever decided if the patent is challenged in court. For an accused infringer, an independent prior art search is therefore the first real technical scrutiny the patent has ever received.
Which court hears a South African patent revocation case?
The Court of the Commissioner of Patents, a specialist court of the Gauteng Division of the High Court seated in Pretoria, has nationwide first-instance jurisdiction over patent infringement and revocation. First-instance matters are decided by a single High Court judge sitting as Commissioner. Johannesburg, in the same Gauteng province, is where most of the corporate parties and litigation teams are based. Appeals go to the Supreme Court of Appeal in Bloemfontein, with the Constitutional Court above it for constitutional questions.
How do I invalidate a granted South African patent?
Any interested person may apply to revoke a patent under section 61 of the Patents Act 57 of 1978. The prior-art grounds are lack of novelty (the invention is not new over the state of the art) and obviousness (it lacks an inventive step). You can bring revocation as a standalone application or as a counterclaim in reconvention if the patentee sues you for infringement first. Because South African courts treat each ground as a separate cause of action and res judicata can bar a second attempt, you should marshal your full prior-art case at once.
Why does prior art matter more in South Africa than in the US or Europe?
Because nothing was vetted at grant. In the US and Europe an examiner searches the art and the file wrapper gives a defendant a floor of citations to build on. In South Africa’s depository system there is no such floor — the claims may be broader than any foreign examiner would have allowed, and the court decides novelty and inventive step solely on the record the parties present. The party that assembles the more complete, better-dated prior art controls the outcome, which makes a rigorous invalidity search decisive rather than merely corroborative.
