YIVAHUBProtecting a Product Design in China: What Actually Works, and What an NDA Will Not Do
2026-10-19 · YIVAHUB Team
The version of design theft most buyers worry about is dramatic: a factory takes your drawings and sells your product behind your back. The version that actually happens is quieter. A buyer ordering from the same factory sees your product on the line. A mould or sample leaves the workshop with a departing employee. Or your listing photographs get scraped and a copy appears on a marketplace before your first container lands. Each needs a different answer, and none is solved by an NDA alone.
An NDA is necessary, cheap and not sufficient. Sign one with every factory you send drawings to: it costs nothing and removes the argument that the design was shared casually. Then be realistic about what it does. Enforcing a cross-border NDA means a Chinese court case, which means a local lawyer, a translated evidence bundle, a filing fee, and six to eighteen months before a judgment you then have to enforce. Realistic budgets start in the tens of thousands of renminbi, which is worth spending when a competitor is selling your product at volume and not worth spending over one listing. The NDA is a deterrent and a piece of evidence, not a lock.
File the registered design before you show it, not after. China grants design patents that are genuinely useful here: a term of 15 years, and a grant that typically takes four to eight months through the normal route, with a priority examination channel that can compress that to weeks for qualifying cases. Official fees are small, in the low hundreds of renminbi, and an agency will add roughly 1,000 to 3,000 renminbi for the filing. The timing matters because a design patent must be novel at filing: publish a photograph, ship a product or show it at a fair before you file and you can destroy your own application. File first, then send the drawing to the factory. If your product's value sits in its appearance, this is the single cheapest protection available and the one buyers most often skip because it feels premature.
Trademarks are the filing with the worst downside if you skip it. China registers on a first-to-file basis, not first-to-use, so whoever files owns the mark. For a lighting or furniture business the classes that matter are 11 for lighting apparatus, 20 for furniture, 21 for household ware, and 35 for retail and wholesale services. Expect nine to twelve months to registration through the standard route, with official fees in the low hundreds of renminbi per class plus an agency fee. If someone files your brand first, your options are to buy it, to oppose it inside the publication window, or to rebrand, and the first routinely costs ten to fifty times what filing would have cost. File the name before the first order, in the classes you actually sell in.
Copyright registration is the cheap evidence you will be glad to have. Copyright exists automatically the moment you draw something, but automatic rights are hard to prove with a date on them. A copyright registration certificate, plus dated drawing files and the original working files, turns a claim about who created what into a document. It is inexpensive, can cover a whole collection of product images at once, and is the fastest route to a marketplace takedown when a copy of your listing appears.
Operational controls beat legal ones on cost, every time. Split the product: have one supplier make the housing, another the driver, another the glass, and assemble at a fourth. A factory that holds one third of a design cannot copy the product, only its part. Keep the component that carries your performance in-house or with a supplier you already control. Own the tooling and, if the volume justifies it, hold the moulds at your own address or at a third party rather than at the factory that uses them. Serialise your finished goods so a stray unit can be traced to a production run. And control what you send: dimensioned drawings to the factory that needs them, photographs everywhere else. Most designs are lost not to malice but because the buyer sent a complete package to three suppliers who all knew each other.
Accumulate the evidence from day one, because you cannot assemble it retroactively. Keep the dated drawing files and the emails that sent them. Keep the tooling invoice showing you paid for it. Keep the mould ownership letter, signed, with the mould's dimensions and photographs. Keep the QC photographs of the first run and the shipment records showing your model number and dates, and the chat records where the design was discussed. None of it costs anything at the time, and all of it is what a lawyer asks for on day one.
When it does happen, work up a ladder rather than jumping to the top. Start with the factory, in writing, with the evidence: a surprising number of cases end there because the leak was a salesman showing a sample, not a decision to copy. If the goods are on a marketplace, file the takedown with the platform and the copyright or design certificate; that is free and often resolved in days. Then the customs recordal, which lets border authorities detain suspected infringing exports and lasts up to ten years, renewed; it is inexpensive relative to everything else here, and most buyers never use it. Then an administrative complaint to the local market supervision authority, cheaper and faster than litigation. Litigation is the last rung, for cases where a competitor is selling at volume and you can prove the numbers.
Design for copy resistance before you design for looks. A product built from a complex assembly, mixed materials and a finish that is hard to reproduce is a worse copy target than a simple shape in one material, and that decision is made on the drawing board, not in a lawyer's office. Copying a simple acrylic cylinder is a weekend's work; copying a seven-part assembly with a specific plating bath is not. Where the appearance is the product, protect the appearance. Where the performance is the product, make the appearance hard to reproduce and the performance hard to observe.
The short version. File the design patent and the trademark before you send anything to a factory. Register the copyright so you have a dated certificate. Sign the NDA anyway, knowing it is a deterrent rather than a lock. Split the build so no single supplier holds the whole design. Own the tooling and keep the paperwork that proves it. Then keep the evidence file current: every enforcement route above runs on dated documents, not on being right.
Where this fits in an order. None of it is expensive, and all of it is easier before the first drawing leaves your desk than after the first copy appears. We file the design registration and the trademark record as part of the set-up for a new product line, and we structure the supply split so that no single factory holds a complete design. Send the product, the quantity and the destination, and the protection sequence comes back with the sourcing plan rather than after it.
