Nobody Owns the Refill: SKUBU, the Big Chains, and What South African IP Law Actually Protects
A photo is doing the rounds. Refill dispensers on the shelves of a big retail chain, selling maize meal at R10 a kilogram, cooking oil by the millilitre, cake flour by weight. The comments all say the same thing: they stole SKUBU's idea.
It is a fair reaction. It is also, legally, the wrong question.
First, the facts
SKUBU launched in Diepsloot in 2025. It is run by Sonke, a South African IoT startup, with the CSIR and the Department of Science, Technology and Innovation, and with backing from TransForm — the accelerator led by Unilever, the UK FCDO and EY. Sonke's contribution is the hardware and the back-end software that tracks stock from delivery through to the dispenser.
But look closely at the machines in the chain store. They are branded Smartfill. Smartfill is a separate South African venture, built by DY|DX with the Smollan Group. It has been rolling dispensers into spaza shops in Tembisa since 2025, and it has pilots in Kenya, Bangladesh and Zambia. It is also backed by TransForm.
So this is not a supermarket reverse-engineering a startup. It is one refill platform winning shelf space that another wanted. And both of them are downstream of something much older.
The spaza shops were first
Decanting is not new in South Africa. Paraffin by the bottle. Cooking oil by the cup. Sugar, rice and mielie meal scooped from a bulk bag into whatever the customer brought. Water vending machines. The sachet economy exists precisely because poor households buy in the quantities they can afford.
That is not a footnote. In patent law it is prior art, and prior art does not care who monetised the idea first.
What South African law protects, and what it does not
There is no property in an idea. The Copyright Act 98 of 1978 protects the expression of a work, not the concept behind it. "Sell staples by weight from a machine" is a concept. Nobody owns it.
Patents are narrower than people think. Section 25(2) of the Patents Act 57 of 1978 excludes a scheme, rule or method for doing business, and a computer program as such. A refill retail model is not patentable. A novel metering mechanism inside the dispenser might be.
And novelty in South Africa is absolute. Under section 25(5) and (6), the state of the art is everything made available to the public anywhere in the world, by description or by use. There is no general grace period — sections 26 and 27 cover only unlawful disclosure and recognised international exhibitions. A launch event, a CSIR press release or a viral TikTok is self-inflicted prior art if you have not filed first.
It gets sharper. South Africa is a depository system. CIPC grants patents without substantive examination. A granted South African patent proves you paid the fee, not that you invented something. It stays exposed to revocation under section 61 for the life of the patent.
Registered designs are the one door still open. Under the Designs Act 195 of 1993, an aesthetic design must be new and original; a functional design must be new and not commonplace in the art. Crucially, section 14 gives a six-month grace period from first release to the public. The shape of a dispenser housing, the kiosk, the store fascia — those are filable, if you move inside the window.
Trade marks are the strongest asset, and the most neglected. SKUBU is a coined, distinctive mark. "Refill Here" and "Save Money Every Day" are descriptive and laudatory, and will not survive section 10(2)(b) on their own. Get-up in yellow and black could function as a mark, but only on proof of acquired distinctiveness. Against a chain trading in red livery, there is no likelihood of confusion and no passing off. Copying a business method is not a misrepresentation as to origin.
Unlawful competition will not fill the gap. Schultz v Butt recognised springboarding off a rival's actual work product. But Payen Components v Bovic Gaskets is the controlling answer: there is no general delict of copying, competition is lawful until it crosses a recognised norm, and the common law will not manufacture a monopoly the IP statutes deny. Emulating a store format, without breach of confidence and without misrepresentation, is lawful.
The real exposure is confidential information. If a concept, unit economics or cost model was disclosed to a retailer or supplier under an NDA and then appeared on a shelf, that is a live claim. It has nothing to do with patents. It is contract and breach of confidence — and once the store is open to the public, only the non-public parts still qualify.
So what is actually novel?
Not refilling. Not selling by the kilogram. The defensible ground is narrow and technical:
the metering and dispensing mechanism, if it is genuinely different;
fixed price per kilogram or litre irrespective of refill size — a pricing architecture, expressed in software;
IoT traceability from receipt to dispatch to restock to sale;
food-safe dry-goods dispensing at township price points;
the SKUBU brand and store identity.
The practical advice
For any founder in this space, three things matter more than outrage.
File designs inside the six-month window. Register the trade mark in retail services and in dispensing apparatus, and file nationally across the Southern African markets you are scaling into — South Africa is not a Madrid Protocol member, so there is no single filing shortcut.
And check your software chain of title. Section 21(1)(d) of the Copyright Act vests commissioned works in the client only for photographs, portraits, engravings, sound recordings and films. Software is not on that list. If contractors wrote your dispenser firmware without a written assignment under section 22(3), you do not own it. That is what kills a funding round, not a competitor's shelf.
The honest conclusion
The chains did not steal anything they could have been stopped from taking. Spaza owners have been refilling for decades and never had a right to assert. The startups formalised it, metered it and put a brand on it — and the only parts they can hold are the parts they registered.
Innovation without an IP strategy is a free case study for whoever has more shelves.
