Infringement Analysis in Johannesburg.

A patent infringement analysis Johannesburg litigators can build on has to be scoped for one fact that reshapes every South African patent dispute — the patent being enforced was never examined for novelty or inventive step before it was granted. South Africa is a non-examining, depository jurisdiction: the CIPC grants patents on formal compliance alone, so validity is only ever tested when a patent is attacked in court. Johannesburg is the commercial engine of Gauteng, home to the country’s mining-technology, financial-services, manufacturing and energy sectors, and the disputes those industries generate are decided by the Court of the Commissioner of Patents. PerspireIP builds the claim charts and prior-art evidence that prove — or defeat — both infringement and the underlying validity of the right.

Where a patent infringement analysis Johannesburg case is decided

Johannesburg is South Africa’s commercial capital and the beating heart of the Gauteng economy, but the court that hears its patent disputes does not sit in the city itself. Every first-instance patent matter in the country — wherever the parties are based — is decided by the Court of the Commissioner of Patents, a specialist court that has its seat in Pretoria and exercises jurisdiction nationwide. The Commissioner is a judge of the Gauteng Division of the High Court, appointed on an ad hoc basis to sit as the single tribunal for patents. Johannesburg-based companies litigate here, roughly an hour up the road, so the practical centre of gravity for a dispute is Gauteng even though the bench is in Pretoria.

That single-court structure matters for how a case is built. Because one specialist forum hears every South African patent action, the evidence that an accused product reads on the claim — and the evidence that the patent should never have survived — both have to be litigation-ready for the Court of the Commissioner of Patents from the outset. An appeal from the Commissioner goes to the Supreme Court of Appeal in Bloemfontein, and constitutional questions can reach the Constitutional Court.

• Court of the Commissioner of Patents — the single, specialist first-instance forum for all South African patent infringement and revocation matters, seated in Pretoria with nationwide jurisdiction
• Gauteng Division of the High Court — the division whose judges sit as Commissioner; Johannesburg is its commercial hub driving the bulk of technical disputes
• Supreme Court of Appeal (Bloemfontein) — the appellate court for decisions of the Commissioner
• CIPC (Companies and Intellectual Property Commission) — the national office in Pretoria that grants and maintains the patents being enforced

The depository patent: granted without examination, tested only in court

The fact that reshapes strategy in South Africa is what the CIPC does not do. South Africa runs a non-examining, depository system: the Companies and Intellectual Property Commission grants a patent once the formal and procedural requirements are met, without ever searching the prior art or assessing whether the invention is new or involves an inventive step. The responsibility for ensuring the claims are valid rests entirely on the applicant. A granted South African patent therefore carries no official presumption that it was scrutinised for patentability — because it never was.

The consequence is direct: validity is only ever tested when the patent is challenged, in a revocation application or as a counterclaim inside an infringement action. Novelty and inventive step, which in an examining country are fought out before the patent office at grant, in South Africa surface for the first time in the courtroom. That puts prior art at the centre of every serious dispute. A patentee suing on an unexamined patent is asserting a right whose foundations have not been stress-tested; an accused party is very often a search away from knocking it out.

The CIPC has signalled a long-term move toward substantive search and examination, and has run initiatives inviting applicants to have applications examined, but a full mandatory examination regime is not yet in force. For any patent enforced today, the depository model still governs: the invention’s validity has not been decided by anyone until the Court of the Commissioner of Patents decides it. That is why an infringement analysis here can never be a pure claim-chart exercise — it has to be paired with a validity view from the first day.

It also changes how a portfolio should be read. A cluster of South African patents in the same family may look formidable on paper, yet each was granted on the same unexamined basis, so the real strength of the portfolio is unknown until the prior art is run. For an operating company weighing a product launch in Gauteng, that uncertainty cuts both ways: the blocking patent it fears may be far weaker than its grant date suggests, while its own granted rights may not withstand the first serious challenge. Reading those odds correctly — before money is committed to an interdict or a redesign — is the practical value of an early analysis in a depository jurisdiction.

Section 65 infringement, section 61 revocation and the remedies at stake

South African patent enforcement runs on the Patents Act 57 of 1978. Infringement proceedings are brought under section 65, and the relief a successful patentee can obtain is substantial: an interdict (the South African injunction) to stop the infringing conduct, delivery up of infringing products for destruction, and damages. In place of proven damages, a plaintiff may instead elect an award calculated as a reasonable royalty in respect of the infringing use — a route that avoids the difficulty of quantifying lost profits.

The defining feature of section 65 is that validity travels with it. Under section 65(4), a defendant sued for infringement may counterclaim for revocation of the patent and, by way of defence, rely on any ground on which the patent could be revoked. Because the patent was never examined, that counterclaim is not a formality — it is frequently the whole case. The grounds live in section 61.

• Section 61(1)(c) — the invention is not patentable under section 25: not new, or lacking an inventive step. This is the workhorse ground in an unexamined system, and it turns entirely on prior art
• Section 61(1)(a) & (b) — the patentee is not entitled to the patent, or it was obtained to defraud the rights of another
• Section 61(1)(d) & (e) — the specification does not sufficiently describe or enable the invention, or the claims are unclear or not fairly based on the disclosure
• Section 61(1)(f), (g) & (h) — a material declaration was false, the grant or an amendment was obtained by fraud or misrepresentation, or the patent falls foul of section 36

Novelty and inventive step are defined in section 25 — a patentable invention must be new, involve an inventive step, and be capable of use in trade, industry or agriculture — with obviousness assessed under section 25(10) against the state of the art at the priority date. For both sides, the section 61 grounds and the section 65 remedies are two ends of the same file.

How an unexamined patent changes the claim chart and prior-art strategy

In an examining jurisdiction, a claim chart can lean on the fact that an examiner already searched the art and allowed the claims. In Johannesburg that comfort does not exist. The claim chart still has to map every limitation of the asserted claim against the real accused product or process, but it has to be built knowing the claim scope itself is unsettled — because construction, novelty and inventive step will all be argued for the first time before the Commissioner. A chart that ignores validity is only half a case.

That is why a South African infringement analysis is inseparable from a prior-art search. For a patentee, the search runs defensively: before spending on an interdict application, confirm the patent can survive the section 61(1)(c) attack that is certain to come by way of section 65(4) counterclaim. For an accused party, the same search runs offensively — a single piece of pre-priority art that anticipates or renders obvious the claim can revoke the patent and end the infringement case in one move. The unexamined grant means the strongest defence is often not “we don’t infringe” but “the patent is invalid.”

The unexamined grant also changes the economics of a threat. In an examining country, a cease-and-desist letter carries the implicit weight of an examiner’s earlier allowance; in South Africa it does not. A recipient who commissions a fast prior-art search can frequently reply not with a non-infringement argument but with an anticipation or obviousness case that puts the patent’s survival in doubt — and, because section 65(4) lets that case be run as a counterclaim, the patentee then risks losing the right entirely rather than merely losing the skirmish. Both sides therefore need to know where the art sits before the first letter is sent, not after litigation has started.

Practically, we build the two threads together: an element-by-element infringement chart grounded in a defensible claim construction, and a prior-art record pinned to the priority date that either shores the patent up or takes it down. The searches reach patent and non-patent literature alike — conference papers, standards, product manuals and, for the mining sector, decades of engineering publications that never made it into a patent database. The mix depends on which side of the dispute you are on, but the discipline is the same — in a depository system, infringement and validity are never separate questions.

Johannesburg’s industries: what the asserted patents claim

Johannesburg’s litigation profile is written by the industries that built the city. It grew on gold, and mining technology remains a signature sector — deep-level mining equipment, drilling and rock-breaking systems, mineral processing, safety and ventilation technology and mine automation. These are hardware-heavy patents where infringement is proven from teardowns, engineering drawings and process analysis, and where the pre-priority art often sits in decades of accumulated mining engineering literature.

A second stream flows from the city’s role as the financial capital of the continent. Home to the Johannesburg Stock Exchange and the major South African banks, the city anchors a fast-growing fintech cluster whose disputes touch payment systems, security methods and software-driven financial platforms. Infringement in these cases rarely sits on a datasheet; it has to be reconstructed from product behaviour, transaction flows, APIs and documentation, then charted against every limitation of the claim. Around these sit Gauteng’s manufacturing base — automotive components, industrial and consumer goods — and a strained but active energy sector where patents read on power generation, grid technology and the renewable and solar systems now being deployed at scale to fill the gap left by an overstretched national grid.

Whether the technology is a rock drill, a payment protocol, an automotive component or a solar-inverter design, the commercial question in front of the Court of the Commissioner of Patents is identical: does the accused product or process fall within the scope of a valid claim? Answering that — scope, infringement and validity together — is exactly what a patent infringement analysis Johannesburg companies can rely on is designed to do.

How PerspireIP builds a Johannesburg infringement-analysis file

Every engagement follows the same disciplined path, tuned to South Africa’s unexamined system. We fix the claim scope first — the correct construction from the claims, specification and prosecution history — then map each element against the real accused product or process. For mining and manufacturing we work from teardowns, engineering drawings and process analysis; for fintech from documented behaviour, APIs and reverse-engineered functionality; for energy from system datasheets and deployment evidence — charting infringement literally and, where appropriate, on a purposive construction.

• Claim construction and element-by-element charting against the accused product, built for the Court of the Commissioner of Patents
• A parallel prior-art search pinned to the priority date — defensive for a patentee, offensive for an accused party under section 61(1)(c) and section 25
• Infringement and non-infringement positions built for either side of a section 65 action, including a section 65(4) revocation counterclaim
• Evidence-of-use assembly — teardowns, technical datasheets, engineering and public technical sources — dated and documented
• Deliverables scoped to the remedies at stake: an interdict application, delivery up, or a damages or reasonable-royalty inquiry

We work alongside your South African and international counsel as a specialist analysis partner, deliver to the Commissioner’s deadlines, and keep every engagement confidential. Whether you are a Johannesburg mining-technology, financial-services, manufacturing or energy company enforcing a patent, an accused party clearing a path to market, or litigation counsel preparing a complaint or a defence, we scale to fit — a single claim chart, a multi-patent matter or ongoing portfolio support. Send us the patent number and the accused product, and we will scope a patent infringement analysis Johannesburg project within one business day.
