Patent Invalidation in Johannesburg.

A patent invalidation Johannesburg strategy has to begin with a fact that sets South Africa apart from almost every other market: patents here are never examined for novelty or inventive step before they are granted. The Companies and Intellectual Property Commission (CIPC) operates a depository, or registration, system — it checks that the paperwork is in order and issues the patent. Nothing in the grant tells you whether the invention was actually new. That question is only ever answered later, in revocation proceedings or as a validity defence in an infringement suit before the Court of the Commissioner of Patents. PerspireIP builds invalidity-grade prior-art searches for the accused parties, generic entrants and licensees who have to prove, for the first time, that a granted South African patent should never have existed.

Why patent invalidation Johannesburg cases live or die on prior art

In most jurisdictions a patent has already survived a national examiner before anyone challenges it. A validity attack there is a second opinion. In South Africa there is no first opinion. The CIPC grants patents on a non-examining basis: it does not search the prior art, does not test novelty and does not assess inventive step. A granted South African patent is therefore an untested right, and the very first substantive scrutiny of its validity happens when someone attacks it.

That inverts the usual burden of a patent invalidation Johannesburg matter. There is no examiner’s file wrapper of cited references to build from, no prosecution history narrowing the claims, and no prior finding that the invention was patentable. The challenger starts from a blank page. Whatever prior art defeats the patent has to be found, dated and charted from scratch — which makes the invalidity search not a supporting exhibit but the entire foundation of the case.

The practical upside is leverage. Because these patents were never filtered, a meaningful share of them are vulnerable to a novelty anticipation or an obviousness combination that a proper search will surface. Johannesburg, as South Africa’s commercial capital and the base for most litigants and their counsel, is where those attacks are scoped and coordinated even though the court itself sits in Pretoria.

• CIPC — grants South African patents without substantive examination for novelty or inventive step
• Court of the Commissioner of Patents — the specialist forum, in the Gauteng Division of the High Court, that hears validity and infringement
• Revocation action — the standalone route to have a granted patent declared void
• Validity defence / counterclaim — invalidity raised inside an infringement suit

A patent office that grants without examining

The Companies and Intellectual Property Commission administers the Patents Act 57 of 1978 through the Patent Office in Pretoria. A complete application with a specification and claims that clears the formal and procedural requirements will be accepted and granted. The Registrar of Patents does not conduct a substantive search of the state of the art, and there is no pre-grant examination on the merits and no pre-grant opposition procedure of the kind found at the EPO or the USPTO.

For a challenger this has two consequences. First, the state of the art relevant to the claim was never assembled by anyone, so it has to be reconstructed. Second, there is no presumption of validity built on an examiner’s review to overcome — the patentee cannot point to a national search report that vetted the invention. The contest is decided purely on the references the parties put before the court.

South Africa has for years signalled an intention to move toward substantive search and examination, and a substantive examination regime has been discussed as part of wider IP-policy reform. Until that is fully implemented, however, the depository model still governs the patents being litigated today, and every granted right in force was issued without a novelty or inventive-step check.

The Court of the Commissioner of Patents in Pretoria

Validity and infringement in South Africa are both decided by the Court of the Commissioner of Patents. It is a specialist court seated in the Gauteng Division of the High Court in Pretoria, and the Commissioner is a judge of that division designated to hear patent matters. Unlike the bifurcated systems of Germany or Austria, South Africa hears infringement and validity together: an accused party can defend an infringement suit by attacking the patent, and can bring a counterclaim for revocation in the same action.

Proceedings are conducted largely on affidavit under the Patent Regulations, with expert evidence on the technology and on the state of the art. A revocation applicant lodges and serves the application, the patentee delivers a counterstatement in the form of a plea, and the parties exchange evidence before the matter is argued. Because there was no examination record, the expert prior-art evidence carries far more weight than it would in a jurisdiction where an examiner had already spoken.

The absence of a bifurcation rule matters strategically. In Germany or Austria a defendant must run validity in a separate forum from infringement, which can leave an injunction in force while the nullity case is still pending. In South Africa the same judge hears both, so a strong invalidity case can be deployed as an immediate shield against the infringement claim rather than parked on a parallel track. South Africa’s Constitutional Court has confirmed how validity operates as both a sword and a shield in these proceedings, underlining how central the invalidity evidence is to the whole dispute.

Appeals from the Court of the Commissioner of Patents go to the Supreme Court of Appeal in Bloemfontein, and from there, on constitutional issues, to the Constitutional Court. Johannesburg, an hour south of the Pretoria court and home to the bulk of the country’s commercial litigants and patent attorneys, is where most of these disputes are instructed and managed.

Revocation grounds under the Patents Act 57 of 1978

Section 61 of the Patents Act 57 of 1978 sets out the grounds on which a patent can be revoked, and importantly it opens the door widely: any person may apply for revocation of a patent. This is unusually broad standing — a challenger does not have to be a defendant, a competitor or even affected by the patent to bring the action. The grounds map directly onto what an invalidity search is designed to prove.

• Not new — the invention was anticipated by matter made available to the public before the priority date
• Not inventive — the invention was obvious to a person skilled in the art having regard to the state of the art
• Not a patentable invention — the subject-matter is excluded, or lacks utility
• Insufficiency — the specification does not disclose the invention clearly enough for it to be performed
• Claims not clear or not fairly based on the specification, or the claims are not supported
• False statement or misrepresentation material to the grant, or the applicant was not entitled to apply
• Prior claiming and other technical grounds set out in section 61

Novelty and inventive step are the grounds that dominate in practice, and both are decided entirely on the prior art. Because no examiner ever searched it, the party who assembles the most complete and best-dated body of references controls the case. A single anticipating disclosure that predates the priority claim can end the patent outright.

The DABUS effect: why unexamined patents demand rigorous searching

South Africa drew global attention in 2021 when the CIPC became the first office in the world to grant a patent naming an artificial intelligence, “DABUS”, as the inventor. The same application was refused or deemed withdrawn in the UK, at the EPO, in the United States and elsewhere. The reason it survived in South Africa is precisely the feature that matters here: with no substantive examination, the CIPC does not interrogate inventorship or patentability at grant in the way examining offices do.

The DABUS episode is a vivid reminder that a South African grant certifies far less than a grant from an examining office. It is a headline case, but the underlying point applies to every patent on the register: acceptance by the CIPC is not a finding that the invention is new, inventive or even properly a patentable invention. Those questions remain fully open, to be resolved only if and when the patent is challenged.

For anyone accused of infringing a South African patent, that is an opportunity rather than a threat — provided the prior art is actually found. The strength of an invalidity attack in this jurisdiction is bounded only by the quality of the search behind it, because there is no examiner’s work to lean on and nothing but the references decides novelty and obviousness.

Where Johannesburg’s patent disputes come from

Johannesburg’s dispute mix tracks its industrial base, and that base begins underground. The city grew on the Witwatersrand gold reef, and South Africa remains a global centre of mining and minerals technology — drilling, comminution, ore processing, tailings and mine-safety systems generate a steady flow of mechanical and process patents. Invalidating those often turns on decades-old machinery, trade catalogues, standards and operating manuals rather than on a headline patent family.

Financial services and fintech form the second pillar. Johannesburg is the seat of the JSE and the continent’s financial hub, and payments, banking-technology and software-implemented inventions increasingly surface in patent disputes. Manufacturing, automotive components, energy — including renewables and off-grid technology — and agri-processing round out the caseload, each with its own prior-art landscape.

The non-examining system shapes the search itself. Where an examining office would have cited the closest patents on the file, here nothing has been cited at all, so the anticipating disclosure is as likely to be a trade journal, a supplier catalogue, a university thesis or a piece of prior use as it is to be a patent. Non-patent literature therefore carries disproportionate weight in a South African matter, and it has to be hunted deliberately rather than pulled from a patent database.

Each cluster invalidates differently. A mining or manufacturing matter turns on dated technical literature and physical prior use; a fintech matter turns on older software disclosures, product documentation and non-patent publications; an energy matter often turns on standards and academic papers. The search has to be built for the technology and for the date, not run from a generic template.

How PerspireIP builds a patent invalidation Johannesburg case

Every engagement follows the same disciplined path. Because there is no examiner’s search to inherit, we map the asserted claims element by element, fix the priority date that actually governs each one, and search the global state of the art against that date. We run patent and deep non-patent-literature retrieval in parallel, then build claim charts that the Court of the Commissioner of Patents can follow line by line under sections 61 and the novelty and inventive-step tests of the Patents Act 57 of 1978.

• Claim charting mapped to the section 61 revocation grounds — novelty, inventive step, insufficiency and support
• Parallel patent and non-patent-literature searching tuned to mining, fintech, manufacturing or energy claims
• Public-availability dating evidenced for every reference, since a non-examined grant leaves the whole prior art open
• Prior art sized to your forum — a standalone revocation application or a validity counterclaim inside an infringement suit
• A written invalidity analysis and reference packages ready for the Court of the Commissioner of Patents and your counsel

We work alongside your South African patent attorneys and litigation counsel as a specialist search partner, deliver to the court’s timetable, and keep every engagement confidential. Whether you are a manufacturer facing an infringement suit, a generic entrant clearing a path to market, or litigation counsel preparing a revocation action, we scale to fit. Send us the patent number and your key dates, and we will scope a patent invalidation Johannesburg project within one business day.
