What can you do if a Chinese supplier copies your design?

This happens more often than people expect.

A buyer sends a supplier product photos, drawings, samples, CAD files, packaging ideas, or Amazon listing materials. The supplier says they can make it. A few weeks or months later, the same or very similar product appears on Alibaba, Amazon, Temu, TikTok Shop, or even from another “new” supplier.

The first reaction is usually: “They stole my design.”

That may be true, but legally the next question is: what exactly did they copy? In China, this matters a lot.

What exactly did they copy?

If they copied the product appearance itself — for example the shape, pattern, colour combination, or overall look of the product — the strongest protection is usually a China design patent. Under the PRC Patent Law, a design can protect the visual design of a product, and the protection is based on the drawings or photos shown in the design patent. If you already have a China design patent, you may have a much stronger position.

If they copied your drawings, product design files, photos, packaging artwork, manual, or graphic elements, that may be a copyright issue. This is different from a design patent. Copyright protects original expression, such as product design drawings, engineering drawings, photos, artwork, written materials and other visual content. It does not automatically give you the same protection as a design patent over the manufactured product itself, but it can still be useful if the supplier copied your materials or used them in listings.

If they used confidential information you only gave them for sampling, quotation, or production, then the issue may also involve trade secrets or breach of confidentiality. Under China’s Anti-Unfair Competition Law, trade secrets can include technical or business information that is not publicly known, has commercial value, and has been kept confidential by the owner.

Why a Western-style NDA is often not enough

Before sharing important product information with a Chinese supplier, it is usually better to have a China-focused NNN agreement. NNN means non-disclosure, non-use, and non-circumvention. The “non-use” part is especially important because the supplier should not use your product information to make the product for itself or for another buyer.

Practical steps if this already happened

1. Save evidence first. Do not only argue with the supplier. Save product links, screenshots, chat records, emails, invoices, samples, shipping records, payment records, design files, and the date you first sent the design to them.
2. Identify the real Chinese company. The supplier’s English name, Alibaba shop name, or salesperson’s WhatsApp name may not be the legal party. You need the official Chinese company name. Without that, enforcement becomes much harder.
3. Check what rights you actually have in China. Do you have a China design patent? A China trademark? Copyright evidence? An NNN or OEM agreement under PRC law? The answer changes the legal strategy.
4. Do not wait too long. If the copied product is still at the sample stage or just starting to sell, you may have more leverage. Once it is widely sold by many shops, the situation becomes more difficult.
5. Think about both legal action and business pressure. Depending on the facts, options may include a lawyer letter, platform takedown, administrative complaint, customs IP protection, contract claim, or court action in China. Our China supplier dispute cost guide compares these routes and what drives their cost.

The key point is this: “They copied my design” is not one legal claim. It may be design patent, copyright, trade secret, trademark, unfair competition, or contract breach. The best route depends on what was copied, what evidence you have, and whether the correct Chinese legal entity can be identified.

For future projects

The safer order is simple:

• File key IP in China where possible.
• Use a China-specific NNN before disclosure.
• Use the supplier’s official Chinese legal name.
• Choose PRC law and Chinese court jurisdiction if you want enforcement in China.
• Keep records of every file, photo, sample and message you disclose.
