Protecting Knitwear Designs When You Manufacture in China

Short answer: an NDA signed in English with a Chinese factory is close to worthless on its own. What works, in order: register your trademark in China (it is a first-to-file country), file a design patent (外观设计专利) for the visual design before the sample leaves the building, and register copyright on jacquard artwork and graphics. Then protect what registration cannot — your custom yarn shades, your knitting program files, and your speed. A stitch structure can be reverse-engineered from a finished sweater in about two days, so the realistic goal is not “nobody copies me”. It is “copies arrive late and look worse”.

Every brand asks this question in the same way: how do I stop them copying me? That is the wrong question. Knitwear is one of the easiest categories to knock off — there is no mould, no tooling, no equipment specific to your product. A factory with the same gauge machine can produce your sweater. The right question is which parts of your product can be defended legally and which parts you should defend commercially.

The Defences That Actually Work

A Realistic Budget

For a small brand: a trademark in two classes plus one or two design patents typically runs $1,500-$3,500 including agent fees, plus a few hundred for copyright registration. Against a 3,000-piece first order, that is well under a dollar a piece. Against a hero style you plan to sell for years, it is the best money in the development budget.

Conclusion

Register the trademark before you talk to anyone. File design patents on the garments whose surface design is the selling point. Accept that the structure itself is copyable, and put your energy into the inputs — custom shades, split processes, and a development calendar that moves.

Key Takeaways for Buyers

How HONGTEX Handles Buyer IP

We sign NNN agreements with the brands we develop for, and we do not resell a customer’s pattern, jacquard file or shade recipe into the open market — a development we did for one brand is not a style we show the next. Send your design under an NNN and we will tell you honestly which parts of it are defensible and which parts you should protect by moving fast instead.
