China operates a first-to-file IP system. If you disclose your designs, trademarks, or proprietary technology to a supplier before securing Chinese IP registrations, you are gambling with your most valuable business assets. Here is how to protect them.
Intellectual property theft is not a fringe risk in China sourcing -- it is a structural reality built into the legal system. China operates a first-to-file regime for trademarks, design patents, and utility models. This means that the party who files an application first with the China National Intellectual Property Administration (CNIPA) generally obtains the right -- regardless of who first used the mark, who first designed the product, or who paid for the development. The implications for foreign buyers are profound: every day you delay registering your IP in China is a day of exposure.
The most dangerous misconception among foreign buyers is that their home-country trademark registration, their established use in commerce, or their common law rights provide protection in China. They do not. China does not recognize common law trademark rights. A supplier who registers your brand or design in China before you do becomes the legal owner of that IP within the PRC -- and you may be forced to buy back your own brand or litigate for years to recover it, with no guarantee of success.
This page provides a comprehensive roadmap for foreign buyers to protect their intellectual property when engaging with Chinese suppliers. It covers common theft scenarios, China's IP legal framework, pre-registration strategy, contractual protections, and enforcement options when theft has already occurred.
Your supplier registers your brand name and logo with the China Trademark Office (CTMO) in Class 35 (retail/sales), Class 9 (electronics), Class 25 (clothing), or other relevant classes -- before you do. Once registered, the supplier can demand you cease using your own brand in China or pay a "licensing fee." In some cases, suppliers have used the registered mark to seize goods at Chinese customs for "counterfeiting."
You pay substantial sums for custom molds, dies, and tooling. The supplier retains physical possession of the molds on their factory floor. After your production run concludes, the supplier uses your molds to produce identical or near-identical products for your competitors, often at a lower price because they bear none of the development cost. When you demand the molds back, the supplier claims ownership, asserts a lien for unpaid miscellaneous charges, or simply refuses.
The supplier produces more units than your order quantity -- sometimes deliberately, sometimes as "acceptable overage." Rather than destroying the excess, the supplier sells these "over-run" goods through gray market channels: Alibaba, AliExpress, DHgate, WeChat-based distributors, or directly to regional wholesalers. These authentic-counterfeit products compete with your genuine sales, undermine your pricing, and damage your distribution relationships.
A key employee of your supplier -- often the sales manager who handled your account or the production engineer who mastered your specifications -- leaves to start a competing factory. They take with them your complete product specifications, design files, supplier lists for raw materials, quality control documentation, and pricing structures. Within months, a nearly identical product appears on the market, manufactured by a company you have never heard of, at a significantly lower cost.
Your proprietary product design appears on Alibaba, Global Sources, or Made-in-China.com, offered by a different company -- sometimes your own supplier using a different trade name. The listing uses your product photos, your design specifications, and even your marketing copy. The infringer offers the product at 40-60% of your retail price, often with lower minimum order quantities, directly to your potential customers.
After you terminate the supplier relationship -- for quality issues, pricing disputes, or strategic reasons -- the supplier continues to use your designs, technical specifications, proprietary manufacturing processes, and even your packaging style. They manufacture and sell the products under a slightly different brand name, drawing on the manufacturing know-how acquired through your paid development. Without clear post-termination IP provisions in your contract, this ongoing misuse can be extremely difficult to stop.
The Chinese Trademark Law (revised 2019) governs trademark registration, use, and enforcement in China. The fundamental principle is first-to-file: the first person to file a trademark application with the CTMO is entitled to registration, subject to certain exceptions for well-known marks and bad-faith filings. A trademark registration in China is valid for 10 years from the date of registration and is renewable. China uses the Nice Classification system (45 classes), and protection extends only to the classes in which the mark is registered.
Foreign applicants who do not have a domicile or "real and effective industrial or commercial establishment" in China must file through a Chinese-licensed trademark agent. The Trademark Law provides mechanisms to challenge bad-faith registrations -- Article 32 prohibits registering a mark that "preemptively registers, by improper means, a mark that is already used by another party and has certain influence." However, proving "certain influence" requires evidence of use and reputation in China, which many foreign buyers lack at the time of discovery.
China offers three types of patents. Invention patents protect new technical solutions or improvements to products or processes, require substantive examination, and last 20 years. Utility model patents protect the shape, structure, or combination of a product with practical value, undergo only preliminary examination, and last 10 years. Design patents protect the aesthetic appearance, shape, pattern, or color of a product, require only preliminary examination, and last 15 years (increased from 10 years under 2021 amendments, implementing China's accession to the Hague Agreement).
For most consumer products sourced from China, design patents are the most relevant protection. They can cover the external appearance of a product -- an important safeguard when a supplier produces visually identical copies. Invention patents provide stronger protection for truly novel technical innovations but require a longer, more expensive application process with substantive examination.
The Anti-Unfair Competition Law (revised 2019) provides important supplementary IP protections. Article 9 protects trade secrets -- defined as technical information, operational information, or commercial information not known to the public that has commercial value and is subject to corresponding confidentiality measures by the rights holder. The 2019 revision shifted the burden of proof: once the rights holder demonstrates that it has taken confidentiality measures and that the information has been misappropriated, the alleged infringer must prove non-infringement. Article 6 prohibits confusing another party's trade name, packaging, or decoration that has "certain influence."
China's Criminal Law provides for criminal prosecution of IP offenses when certain thresholds are met. For trademark counterfeiting (Article 213), the threshold for criminal liability is typically illegal business turnover exceeding RMB 50,000 or illegal profits exceeding RMB 30,000, though these figures vary by product category and local prosecutorial practice. For trade secret theft (Article 219), the threshold is causing losses exceeding RMB 500,000 to the rights holder. Criminal enforcement, while powerful in principle, requires cooperation from law enforcement authorities and is typically pursued through the Public Security Bureau's Economic Crime Investigation units.
Key Legal Insight: The interaction between China's first-to-file trademark system and its contract law creates a strategic opportunity. Under Article 15 of the Trademark Law, an agent or representative who registers a principal's mark without authorization can be challenged. If your supplier is your contractual "agent" in the relationship, this provision may provide a basis for cancellation -- but only if you have a well-drafted contract establishing the agency relationship and documenting your prior rights.
The single most important IP protection rule for foreign buyers sourcing from China is: register your IP in China before you disclose it to any supplier. This applies to all potential suppliers -- even those you are merely evaluating. IP theft often occurs at the RFQ and sampling stage, before a formal relationship exists.
The optimal timeline is:
Critical Timing Warning: An international trademark application under the Madrid Protocol that designates China will receive the same filing date as your home-country application -- but only if you file the international application within 6 months of your home filing. If you miss this window, your China designation receives its own filing date, potentially after a supplier has already filed. Treat the 6-month priority period as a hard deadline.
IP registration provides the legal framework for ownership. Your supplier contract provides the contractual framework for use. A comprehensive China supplier agreement should address each of the following IP dimensions:
The contract must state explicitly that all molds, dies, tooling, and fixtures paid for by the buyer (whether in whole or in part) are the sole and exclusive property of the buyer. This clause should include: (a) a detailed schedule listing each mold/tool by description and serial number; (b) a requirement that the supplier affix labels or plates to each mold identifying it as buyer's property; (c) an obligation on the supplier to maintain insurance for the full replacement value of molds in its possession; (d) a post-termination return obligation requiring the supplier to release all molds to the buyer (or its designated carrier) within a specified number of days after contract termination, at the supplier's cost for packaging and preparing for shipment; and (e) a prohibition on the supplier exercising any lien, retention right, or set-off against the molds for any alleged debt.
Non-circumvention clauses prohibit the supplier from directly contacting or dealing with your customers, distributors, or end-users. Non-compete clauses restrict the supplier from manufacturing the same or substantially similar products for any other customer during the contract term and for a defined period thereafter. However, both types of clauses face enforceability challenges under Chinese law. Under Article 497 of the Chinese Civil Code, standard terms that unreasonably restrict the rights of the other party may be deemed invalid. To maximize enforceability: (a) limit the non-compete to a reasonable geographic scope and time period (typically 1-2 years post-termination); (b) tie the non-compete to the specific product designs and technical information disclosed by the buyer, not to an entire product category; and (c) provide for a reasonable compensation payment or consideration for the non-compete period, consistent with Chinese employment law principles that require compensation for post-employment non-competition.
Confidentiality provisions should define the scope of confidential information broadly -- including specifications, drawings, designs, formulas, processes, customer lists, pricing data, and business strategies -- but specify exclusions (information already in the public domain, independently developed, or rightfully received from a third party). The provision should survive contract termination for a defined period (typically 3-5 years, or indefinitely for trade secrets). Critically, the contract should include liquidated damages for breach of confidentiality. Proving actual damages from an IP breach is notoriously difficult and expensive. A negotiated liquidated damages clause -- for example, a fixed amount per breach plus a per-unit royalty on infringing products -- provides a far more practical enforcement mechanism. Under Article 585 of the Chinese Civil Code, liquidated damages may be adjusted by a court if they are "excessively higher than the losses caused," but a well-calibrated liquidated damages provision remains a powerful deterrent and enforcement tool.
A critical but often overlooked issue is: who owns improvements, modifications, or derivative works created by the supplier during the manufacturing relationship? If the supplier develops a more efficient manufacturing method for your product, or modifies the design to reduce cost, who owns that improvement? Your contract should address this explicitly. Options include: (a) all improvements become the buyer's sole property (most protective); (b) the supplier retains ownership but grants the buyer a perpetual, royalty-free, worldwide license; or (c) improvements are jointly owned, with defined rules for exploitation and revenue sharing. The appropriate approach depends on bargaining power and the nature of the relationship, but silence is the worst option -- it invites disputes and may result in the supplier claiming ownership of critical manufacturing know-how.
The contract should grant the buyer (or its designated auditor) the right, upon reasonable notice, to: (a) inspect the supplier's premises to verify compliance with IP obligations; (b) audit production records and inventory levels to detect unauthorized production runs; (c) inspect molds and tooling to confirm their condition and usage; and (d) review sales records to the extent necessary to verify compliance with exclusivity or non-compete provisions. While Chinese suppliers often resist audit clauses, they are a practical necessity for effective IP enforcement.
IP-related contractual disputes present a strategic choice of forum. Chinese courts have jurisdiction over IP rights registered in China and can grant injunctive relief directly enforceable within China. International arbitration (CIETAC, HKIAC, SIAC) may be preferable for contractual breach claims and damages, with the resulting award enforceable through the New York Convention. Many well-structured agreements bifurcate dispute resolution: IP infringement claims (seeking injunctions, administrative raids, border measures) are brought in Chinese courts, while contractual damage claims proceed in arbitration. This approach leverages the strengths of each forum. Governing law should be specified -- typically Chinese law for contracts with Chinese suppliers, as it governs the underlying IP rights and is most readily applied by Chinese courts and arbitrators.
If you discover that your IP has been misappropriated -- a supplier has registered your trademark, is producing counterfeits, or is selling your designs to competitors -- you have several enforcement pathways. The most effective strategy typically combines multiple approaches simultaneously.
China's Administration for Market Regulation (AMR, formerly AIC) has the authority to investigate IP complaints, raid premises, seize infringing goods, impose fines, and issue cease-and-desist orders. Administrative enforcement is generally faster and less expensive than litigation, and does not require the same evidentiary burden. The process: file a complaint with supporting evidence (IP registration certificates, notarized purchase of infringing products, photos) at the local AMR office with jurisdiction over the infringer's location. If the AMR accepts the case, they can conduct a raid -- often within weeks -- and seize infringing goods, packaging, molds, and documentation. Administrative fines for trademark infringement range from RMB 50,000 (approximately USD 7,000) to five times the illegal turnover. The limitation: AMR cannot award damages to the rights holder. For monetary recovery, civil litigation is necessary.
Civil IP litigation in China has improved significantly in recent years, particularly in specialized IP courts established in Beijing, Shanghai, Guangzhou, and the Hainan Free Trade Port. These courts have experienced judges, streamlined procedures, and a growing body of published decisions. A civil IP claim can seek: (a) a permanent injunction against further infringement; (b) damages -- either the rights holder's actual losses, the infringer's illegal profits, or statutory damages up to RMB 5 million (approximately USD 700,000) for trademarks and up to RMB 5 million for design patents (increased under 2021 patent law amendments); (c) destruction of infringing goods and manufacturing equipment; and (d) publication of the judgment at the infringer's cost. Important: Chinese courts can also award punitive damages (up to five times the base damages) for intentional, serious IP infringement under revisions to the Trademark Law, Patent Law, and Anti-Unfair Competition Law.
For large-scale, organized counterfeiting operations, criminal prosecution through the Public Security Bureau (PSB) is available. The thresholds for criminal IP offenses are relatively low: trademark counterfeiting (Article 213, Criminal Law) requires illegal business turnover exceeding RMB 50,000 or illegal profits exceeding RMB 30,000; copyright piracy (Article 217) requires illegal business turnover exceeding RMB 50,000 or more than 500 infringing copies; trade secret theft (Article 219) requires causing losses exceeding RMB 500,000. Criminal enforcement offers the strongest deterrent effect -- penalties include imprisonment (up to 7 years for serious trademark counterfeiting, up to 10 years for trade secret theft) and criminal fines. However, criminal investigation depends on the PSB's willingness to pursue the case, which varies by region and the scale of the infringement.
China Customs (General Administration of Customs, GAC) offers IP recordation and border enforcement. Rights holders can record their registered IP rights (trademarks, patents, copyrights) with GAC's IP Protection System. Once recorded, customs officials are required to detain goods suspected of infringing recorded IP rights. The detention is ex officio -- customs acts on its own initiative during routine inspections, without requiring a specific complaint from the rights holder for each shipment. The rights holder is notified of the detention and must confirm within 3 working days (for trademarks/copyrights) or provide a bond for patent cases that the goods are infringing and request continued detention. Border seizure is particularly effective for preventing export of counterfeit goods -- a common scenario when a Chinese factory produces counterfeits destined for overseas markets.
Major Chinese e-commerce platforms including Alibaba (Taobao, Tmall, 1688.com, Alibaba.com, AliExpress), JD.com, and Pinduoduo operate IP protection systems that allow rights holders to submit takedown requests. The Alibaba IP Protection Platform (IPP) processes complaints based on registered IP rights and, in many cases, acts within 1-3 business days to remove infringing listings. For foreign buyers discovering their products being sold on Alibaba by competitors or former suppliers, platform takedown is often the fastest initial response. However, it is a whack-a-mole exercise -- infringing listings reappear under different store names -- and must be combined with offline enforcement for a durable solution.
Successful IP enforcement in China depends crucially on evidence preservation. Before alerting the infringer to your discovery, take these steps: (a) notarize all online evidence -- listings on Alibaba, the supplier's website, WeChat conversations, email exchanges -- through a Chinese notary public (this is the gold standard for Chinese court admissibility and worth the cost of approximately RMB 1,000-3,000 per notarization); (b) conduct a notarized test purchase of the infringing product, preserving the full transaction chain from order through delivery; (c) photograph and document any physical evidence, including packaging, labels, manuals, and product markings; (d) preserve metadata -- dates, times, account names, IP addresses -- associated with electronic evidence; and (e) maintain a complete chain of custody for all physical evidence. Chinese courts scrutinize the authenticity and integrity of evidence, and improperly preserved evidence may be excluded.
A US footwear brand had been sourcing from a Dongguan factory for three years when it discovered the factory owner had registered its brand name in China (Classes 18, 25, and 35) six months into the relationship. The factory demanded USD 200,000 for the trademark assignment. The US company was forced to litigate the bad-faith registration under Article 32 of the Trademark Law, ultimately prevailing after 18 months and approximately USD 60,000 in legal fees -- but only because it could prove its mark had achieved "certain influence" in China through sales to Chinese distributors it had not initially disclosed.
A German precision tool manufacturer paid EUR 85,000 for custom injection molds at a Ningbo factory. Its purchase order specified "molds remain property of buyer" but lacked detail on return mechanics. When the relationship ended over quality disputes, the factory refused to release the molds, claiming unpaid storage fees of EUR 15,000. The German company's contract contained no provision prohibiting the factory from exercising a lien over the molds. After 12 months of litigation in Ningbo Intermediate Court, the molds were recovered, but the German company incurred EUR 40,000 in legal costs and lost a year of production.
