Patent Invalidation in Cape Town.

A patent invalidation Cape Town strategy begins with one fact that sets South Africa apart from the United States and Europe: the patent office never examined the patent you are fighting. South Africa runs a non-examining, depository system — the Companies and Intellectual Property Commission (CIPC) checks the paperwork and grants, but it never tests novelty or inventive step. Those questions are decided for the first time only when someone applies to revoke the patent. Cape Town anchors South Africa’s technology economy — the “Silicon Cape” fintech and software cluster, agritech, renewables and medtech. PerspireIP builds invalidity-grade prior-art searches for the Cape Town businesses that must defeat an unexamined patent on the merits.

Why patent invalidation Cape Town starts with an unexamined grant

In most of the world a patent office reads the claims, searches the prior art and refuses what is old or obvious before granting. South Africa does not. Under the Patents Act 57 of 1978, CIPC operates a depository, non-examining system: applications are checked for formalities — the right forms, fees and a complete specification — and then granted. No examiner ever assesses whether the invention is new or involves an inventive step.

The consequence is decisive for anyone on the receiving end of a South African patent. Validity is not confirmed at grant; it is merely presumed until challenged. The novelty and inventive-step questions that a US or European examiner would have resolved before issue are, in South Africa, resolved for the very first time in revocation proceedings — in front of a court, on the evidence the parties put up.

That single feature reshapes strategy. A Cape Town company facing an infringement threat is not arguing against an examiner’s considered grant; it is arguing against a right that no one ever tested. The whole contest turns on the prior art, and the prior art is exactly what a depository system never went looking for.

Unexamined grants are more vulnerable — so the prior-art search is the case

Because no examiner ever ran a search, a South African patent carries no prosecution record of cited art to work around. There is no file wrapper full of rejections, amendments and examiner citations. The claims may be broad, the disclosure thin, and the closest prior art entirely unaddressed — simply because nobody was ever required to address it.

For a challenger, that is opportunity. In an examined jurisdiction the best references are often already on the file and already argued around. Here they are usually still out there, unfound. The single most valuable thing you can do to a South African patent is the search the office skipped — a rigorous, claim-by-claim hunt for the novelty-destroying or inventive-step-destroying reference that pre-dates the priority date.

• No examiner search means no cited-art shield — the strongest references are typically still undiscovered
• Broad, unexamined claims often read straight onto earlier disclosures the patentee never had to distinguish
• Partial revocation is available, so a search can target only the claims that block your product
• The priority date governs, so every reference must be proven public before it — dating is evidence, not a footnote

In a depository system the prior-art search is not a preliminary step. It is the case.

The Court of the Commissioner of Patents: one national court in Pretoria

Patent revocation and infringement in South Africa are heard by a single specialist forum: the Court of the Commissioner of Patents. It is not a separate building or a Cape Town tribunal — it is a specialist court of the Gauteng Division of the High Court, seated in Pretoria, with a judge sitting as Commissioner of Patents. It has exclusive first-instance jurisdiction over patent enforcement across the entire country.

So a Cape Town or Western Cape business does not litigate patent validity in the Western Cape High Court. Wherever the parties sit, a revocation or infringement matter runs before the Commissioner in Pretoria, applying the Patents Act 57 of 1978 nationwide. Cape Town patent attorneys and counsel appear there routinely; the geography of the forum is fixed even when the dispute, the product and the market are entirely local to the Cape.

The two ways to attack a patent both land in that court. Any person may apply to revoke a patent at any time, standing alone. And a defendant sued for infringement may raise invalidity as a defence and counterclaim — a claim in reconvention for revocation — heard together with the infringement claim. Either way, the same prior-art dossier does the work, and appeals run onward to the Supreme Court of Appeal and, on constitutional questions, the Constitutional Court.

Grounds for revocation under section 61 of the Patents Act 57 of 1978

Revocation is not open-ended. Section 61 of the Patents Act 57 of 1978 sets out a closed list of grounds, and an applicant must bring the attack within one of them. In practice the prior-art grounds — lack of novelty and obviousness, both routed through the patentability test in section 25 — are where a well-built search wins or loses the case.

The section 61(1) grounds a Commissioner weighs include:

• The invention is not patentable under section 25 — capturing lack of novelty, absence of an inventive step, and excluded subject matter
• The patentee is not a person entitled under section 27 to apply for the patent
• The grant was obtained in fraud of the rights of the applicant or of anyone through whom that person claims
• The invention as claimed cannot be performed, or does not lead to the results and advantages set out in the specification
• The specification does not sufficiently describe, ascertain and, where necessary, illustrate the invention — insufficiency of disclosure
• The claims are not clear, or are not fairly based on the matter disclosed in the specification
• A prescribed declaration or statement was false in a material particular and known, or ought reasonably to have been known, to be false

Note the split. Novelty is measured against everything made available to the public before the priority date; inventive step asks whether the claimed advance was obvious to a skilled person over that art. Both stand or fall on references, and on proving each reference was genuinely public before the priority date the claim relies on. Getting the date right, and evidencing it, is the evidentiary heart of every section 61 attack — not the keyword hit.

Is South Africa moving to substantive examination?

The depository model has long drawn criticism, and reform has been discussed for years. CIPC has publicly signalled its intention to become a substantive search-and-examination office, and it has recruited and trained a first cohort of technically qualified patent examiners. A phased, opt-in examination pathway for certain complete applications has been piloted rather than imposed across the board.

What matters for anyone challenging a patent today is that the change is still in transition, not a completed, mandatory examination regime. The overwhelming majority of patents currently in force in South Africa — including virtually every patent a Cape Town business is likely to be sued on — were granted with no substantive examination at all. Their validity has never been tested by anyone.

So even as the system slowly modernises, the practical reality is unchanged: the patent asserted against you was almost certainly never searched. The reference that invalidates it is still yours to find, and finding it remains the entire game.

Cape Town’s industries and where the decisive prior art lives

Cape Town’s patent disputes mirror its economy. The city is the heart of South Africa’s technology scene — the “Silicon Cape” ecosystem, home to hundreds of tech firms and the country’s densest concentration of fintech, software and venture capital. Around it sit Western Cape agritech and viticulture, a growing renewables and green-tech base, and a medtech and healthtech cluster tied to the city’s universities and hospitals.

Those are software, data, biological, chemical and mechanical technologies, and they invalidate on very different evidence. The reference that sinks a fintech, agritech, renewables or medtech claim is rarely the headline patent a first-pass keyword search surfaces. Because no South African examiner ever searched, it is almost always sitting in literature no one on the file ever consulted.

• Fintech and software: open-source repositories, technical blogs, standards drafts, product manuals and machine-learning preprints predating the claim
• Agritech and plant science: agronomy journals, field-trial reports, extension papers and older plant and process patent families
• Renewables and green tech: energy-engineering literature, IEC and IEEE standards, conference proceedings and supplier datasheets
• Medtech and healthtech: ISO and clinical standards, regulatory dossiers, device manuals and biomedical publications
• Prior use and public demonstration — a product sold or shown in South Africa or abroad before the priority date can be as fatal as a printed reference

The other half of the work is proof of date. A reference only counts if it was public before the priority date the claim relies on. We treat public-availability dating as evidence — archive timestamps, publication records and library holdings the Commissioner will accept without a side fight over authenticity.

How PerspireIP builds a patent invalidation Cape Town case

Every engagement follows the same disciplined path. We chart the asserted claims element by element, fix the priority date that governs each one, and search against that date rather than the filing date on the cover. Because the patent was never examined, we build the search from scratch — there is no examiner citation list to lean on, which is precisely why the strongest references are still recoverable.

• Claim charts mapped to the section 61 grounds a Commissioner applies — non-patentability under section 25, inability to perform, insufficiency, and lack of clarity or fair basis
• Parallel patent and non-patent-literature searching tuned to fintech, software, agritech, renewables and medtech claims
• Deep retrieval of the foreign-language art, prior-use evidence and grey literature a depository grant never surfaced
• Public-availability dating evidenced for every reference, ready for the record before the Court of the Commissioner of Patents in Pretoria
• Prior art sized to your posture — a stand-alone revocation application or a counterclaim for revocation in defence to an infringement suit

We work alongside your South African patent attorneys and counsel as a specialist search partner, deliver to court deadlines, and keep every engagement confidential. Whether you are a Cape Town fintech or agritech company facing an infringement claim, a licensee clearing a product line, or litigation counsel coordinating a revocation defence, we scale to fit. Send us the patent number and your key dates, and we will scope a patent invalidation Cape Town project within one business day.
