The Country That Sees Your Product First
A US company sourcing overseas shows its complete design to Chinese suppliers long before a single unit reaches an American customer. The factory receives CAD files, a bill of materials, tolerance drawings, firmware binaries, packaging artwork, and often the tooling design itself. That package is the invention, and it lands in China months or years ahead of the launch.
Most founders assume their US patent covers this. It does not. Patents are territorial. A US patent stops importation into the US and nothing else. It has no effect on a factory in Guangdong building the same product for buyers in Europe, Southeast Asia, or Latin America, and it does not stop a Chinese entity from registering the design locally.
First-to-File, With No Softening
China awards rights to whoever files first, and the rule is applied without the equitable carve-outs American inventors expect. There is no general grace period for your own prior disclosure the way US law provides. If your product has been publicly shown, listed, or sold before you file in China, the filing is compromised.
Worse, if a supplier, an employee at a supplier, or an unrelated party files on your design before you do, they hold a valid Chinese right to it. Invalidating it means proving your prior disclosure, which is slow and uncertain, while the registrant blocks your exports and files takedowns against your listings. The same squatting problem hits brand names, since Chinese trademark law is also first-to-file, so a Chinese trademark application belongs alongside the patent work rather than after the US filing covered in how to trademark a product name.
Three Routes, Very Different Cost and Speed
Invention patent. The equivalent of a US utility patent: full substantive examination, a twenty-year term, the strongest right available. Examination runs roughly two to four years, with agent and translation costs of several thousand dollars to file and more through prosecution. Use it for a genuine technical mechanism.
Utility model. The route most American companies have never heard of and the one that often matters most. A utility model covers the shape, structure, or combination of a product, carries a ten-year term, and receives only a formalities examination. Registration commonly issues within six to twelve months, and total cost is often a fraction of an invention patent. It is enforceable in Chinese courts and usable for customs and platform takedowns. Filing an invention patent and a utility model on the same day is a standard strategy: the utility model gives you a fast enforceable right while the invention patent grinds through examination.
Design patent. Protects appearance rather than function, issues in roughly six to nine months, costs the least of the three, and is remarkably effective against direct copies because a knockoff that looks identical infringes regardless of what is inside. If your product has any distinctive visual identity, file one. The drawing discipline is the same as the US process in how to file a design patent.
The Timing Window
Two deadline structures govern how long you have after a first filing elsewhere.
Under the Paris Convention route, you have twelve months from your earliest priority filing to file directly in China with that original date intact. This is the cheapest path and the fastest to an enforceable utility model or design registration.
Under the PCT route, you have thirty months from priority to enter the Chinese national phase, which buys time but delays the point at which you actually hold a Chinese right. The tradeoffs of that delay across all your target countries are worked through in PCT national phase entry, and the country selection logic itself in which countries to patent in.
The practical constraint is that manufacturing moves faster than thirty months. If drawings go to factories at month eight and tooling is cut at month fourteen, waiting until month thirty leaves a long unprotected window during the period of maximum exposure. For anyone sourcing in China, direct filing at the twelve-month Paris deadline or earlier is usually right.
Registration as an Enforcement Tool
A Chinese registration is not just a defensive document. It unlocks mechanisms that do not exist without it.
- Customs recordation. Record the right with Chinese customs and officials can detain infringing goods at the port of export. This is the single most effective tool against copies leaving for third markets, and it is unavailable without a Chinese registration.
- E-commerce takedowns. The major Chinese marketplaces have IP complaint systems that act quickly on a Chinese registration number and largely ignore foreign ones.
- Administrative enforcement. Local IP authorities can order infringers to stop and can seize goods without a full court proceeding, on a timeline measured in months rather than years.
- Leverage with the supplier. A factory that knows you hold Chinese rights behaves differently from one that suspects you hold nothing locally.
Filings Are Half of It
A registration works alongside contracts rather than instead of them. The standard instrument for China manufacturing is not a US-style NDA but a non-disclosure, non-use, non-circumvention agreement written in Chinese, governed by Chinese law, with a Chinese court named and a liquidated damages figure specified. The reasoning is in NNN agreements for China manufacturing. A foreign-law NDA that must be enforced abroad is functionally decorative.
Add the operational controls that limit exposure: split the build so no single factory holds the complete design, keep firmware and calibration data out of the factory's hands, and settle tooling ownership before steel is cut, per who owns your injection mold in China. The realistic threat model is set out in will a Chinese factory copy my product.
Fitting It Into the Development Plan
Sequence it against engineering milestones rather than legal ones. File the US provisional or utility application when the mechanism is defined. Freeze the industrial design and file the Chinese design application before the first supplier package goes out. File the Chinese utility model and invention patent together at or before the twelve-month priority deadline, ideally before tooling release. Record the granted rights with customs as soon as they issue, and register the brand in Chinese characters as well as Latin script.
Total spend for a design registration, a utility model, and an invention patent, including agent fees and translation, commonly lands in the middle five figures. Against a tool set, a container of inventory, and a launch, that is not the expensive part of going to production.
Plan the Filing Around Your Supply Chain
The right filing strategy depends on which parts of your design actually travel to a supplier and when. Projects House helps clients map that exposure across the development and sourcing schedule so the protection lands before the drawings do.
