China OEM Agreements: The Complete Guide for Foreign Buyers

This guide sets out, clause by clause, what an OEM agreement with a Chinese manufacturer should contain, the problems that most commonly arise in practice, the drafting positions that serve a foreign buyer well in negotiation, and the legal and commercial reasons that support those positions, based on our experience of these relationships.

Perspective and terminology. Throughout this guide, “buyer” means the party that commissions the manufacture of products and sells them under its own brand — the purchaser, brand owner or commissioning party. “Manufacturer” means the contract factory that accepts the commission. English-language writing on this subject uses the label “OEM” in both directions — sometimes for the brand, sometimes for the factory — so this guide adopts a single, fixed buyer–manufacturer frame of reference.

How each clause is presented. Every clause is analysed in four dimensions, followed by a risk module:

1. What the clause should contain — the substantive content of a well-drafted clause;
2. Issues to watch — the traps, ambiguities and disputes most frequently reported in practice;
3. Recommended drafting positions — how the clause is best drafted from the buyer’s side;
4. Rationale — the legal and commercial reasons supporting those positions; and
5. Legal risk alerts and countermeasures — how courts have actually treated the issues concerned, and the practical responses available to a buyer.

This is Part 1 of a serialised guide. It opens with the complete clause map, and then addresses the first clause of the intellectual-property cluster: Clause 1 (intellectual property ownership and licensing). The confidentiality clause — Clause 2 in the map below — is not duplicated here, because it is the subject of our dedicated NNN guide. Subsequent parts will address the remaining clauses in the order presented below.

The complete clause checklist: an overview

The clauses of a well-constructed OEM agreement arrange themselves in three tiers:

• Tier 1 — core clauses. These attract the widest agreement across independent sources. An OEM agreement that lacks any one of them leaves the buyer exposed to a risk that is structural rather than marginal.
• Tier 2 — important clauses. Fewer sources treat these as indispensable, but they are essential in particular scenarios — specific industries, specific sourcing geographies, or specific commercial structures — and a buyer operating in those scenarios does well to treat them as core.
• Tier 3 — specialised and boilerplate clauses. China-specific and industry-specific provisions, electronic-execution mechanics, and the general provisions that close out the contract.

Tier 1 — core clauses

1. Intellectual property ownership and licensing — which party owns the designs, technical documentation and inventions that the relationship creates or uses, and on what terms the manufacturer may use them.
2. Confidentiality / NNN — non-disclosure, non-use and non-circumvention obligations governing technical data, pricing, business plans and customer information.
3. Product specifications and scope of work — the exhaustive technical definition of the product, annexed to and controlling under the contract.
4. Quality standards, inspection and acceptance — the applicable standards, the inspection and audit regime, and the acceptance procedure by which risk passes.
5. Warranty and defect handling — warranty period, the split between manufacturing defects and design defects, remedies and the claims process.
6. Price and payment — unit pricing, price-adjustment mechanisms, payment milestones and the leverage they preserve.
7. Delivery, lead times and Incoterms — the delivery regime, the chosen Incoterm (with version), and remedies for delay.
8. Term, termination and post-termination obligations — duration, exit rights, and the wind-down obligations (tooling return, destruction of materials, sell-off periods) that make an exit clean.
9. Indemnification and limitation of liability — representations and warranties, indemnities for third-party claims, and a liability cap structured so that it does not hollow out the indemnities.
10. Dispute resolution and governing law — forum, procedural rules, governing law, and the language hierarchy of a bilingual contract (developed in our guide on courts versus arbitration).

Tier 2 — important clauses

11. Tooling ownership — title to moulds, fixtures and test equipment funded by the buyer, regardless of physical location.
12. Subcontracting and supply-chain control — consent, disclosure, flow-down obligations and audit rights over the manufacturer’s own suppliers.
13. Exclusivity and non-compete — restrictions on the manufacturer producing the same or similar products for others, and on selling around the buyer.
14. Insurance — required coverage, minimum limits, and the buyer’s interest noted on the policies.
15. Force majeure and hardship — a bifurcated structure distinguishing impossibility from fundamental economic imbalance.
16. Forecasts, minimum order quantities and inventory — the rolling forecast mechanism, which parts of it are binding, and who bears excess-stock costs.
17. Regulatory compliance and certifications — responsibility for obtaining and maintaining the certifications that gate market access.
18. Trademark and brand usage — how and to what extent the manufacturer may use the buyer’s marks, and the precise form in which marks are affixed.
19. Improvements and grant-backs — ownership of, and the buyer’s licence to, process and product improvements developed during the relationship.
20. Recalls and product safety — recall leadership, cost allocation and the communications plan.

Tier 3 — specialised and boilerplate clauses

• China-specific practice: refinement of the NNN framework; Chinese-language drafting and text-precedence rules; choice of the contracting entity; and the choice between Chinese arbitration institutions and offshore arbitration (SIAC/HKIAC).
• Industry-specific practice: CCC certification formalities; new-energy-vehicle entrustment manufacturing; cosmetics registration; electronics manufacturing services (EMS); Vietnam export processing; build-transfer production-line handover; and consumer-product safety filings in Japan.
• Execution mechanics: electronic agreements and blockchain-based evidence preservation.
• Boilerplate: notices, entire agreement, severability, government approvals, non-partnership declarations, assignment restrictions, amendment procedure, and the relationship between the master agreement and purchase orders.

What this part covers

This part addresses Clause 1 — intellectual property ownership and licensing — the first of the Tier 1 clauses and the anchor of the intellectual-property protective shell of the OEM relationship. It comes first because it is the clause that must operate before the buyer discloses anything of value — which, in a well-run sourcing process, means before the relationship formally begins. Its companion, the confidentiality/NNN clause, is developed in our dedicated NNN guide.

Clause 1 — Intellectual property: ownership and licensing

Where this clause lives in the contract stack. The IP provisions described here serve two distinct stages of the relationship, and the stage determines which document carries them:

The distinction matters because development-stage IP must be secured before the factory begins any design or development work — waiting until the manufacturing agreement (signed after sample approval) means the default rules have already vested ownership in the factory by then. For single-factory projects with moderate customisation, incorporating the development-stage IP provisions into the NNN keeps everything under one signature. For multi-factory comparison or heavy custom development, a separate development agreement provides fuller attention and negotiation space for those terms.

This clause analysis below covers both stages together, because the substantive content — what to say about ownership, licensing, and protection — is the same whichever document carries them.

What the clause should contain

A complete IP clause in an OEM agreement addresses, at a minimum:

• A layered declaration of intellectual property, distinguishing background IP (the rights each party brought to the relationship) from foreground IP (the rights the relationship creates). The layering is explicit for both sides: the buyer’s pre-existing designs, marks and documentation on the one hand, and the manufacturer’s pre-existing platform technology and know-how on the other.
• Ownership of design documentation — schematics, bills of materials (BOM), Gerber files, firmware, CAD files and industrial designs — stated item by item rather than by general reference.
• The scope of any licence granted to the manufacturer: where the manufacturer needs permission to use the buyer’s IP to perform, that licence is limited to the sole purpose of manufacturing under the contract, restricted to the contract products, and expressed to terminate immediately and automatically upon termination or expiry of the agreement.
• The ODM variant: where the manufacturer develops the design, the buyer faces a structural choice between an assignment (buy-out) of the resulting IP and an exclusive licence. Without one or the other, the manufacturer remains free to license the same design to other brands or to produce and sell it itself (subject only to not using the buyer’s marks).
• Prohibitions, clearly expressed: no production of the same or similar products for third parties during or after the relationship; no assertion of ownership over improvements or derivatives of the buyer’s IP; no reverse engineering of the buyer’s products, software or documentation.
• Infringement notification and cooperation duties: the manufacturer’s obligation to notify the buyer promptly of any suspected infringement it becomes aware of, and to assist reasonably in enforcement actions.
• A non-challenge covenant with respect to the validity of the buyer’s registrations.
• An IP indemnity running from the manufacturer to the buyer for third-party IP claims arising from the manufacturer’s own technology or processes.

Issues to watch

IP is the first consensus of the entire literature. No other clause attracts agreement across as many independent sources. It is also where the most expensive and least remediable mistakes occur.

The ODM IP trap. A widespread and costly misapprehension is that paying a design or development fee conveys ownership of the resulting design. Under Chinese law it does not: absent an express contractual allocation, the default rules vest commissioned inventions and commissioned software in the party that completed the work — the manufacturer (see the Brenner case below). A brand that discovers this only after the relationship has ended, or after the manufacturer has filed its own patents, has very limited remedies.

Over-broad and over-narrow clauses both fail. A one-sided formulation under which “all intellectual property arising under this agreement is assigned” purports to swallow the counterparty’s background IP — an approach that invites rejection in negotiation and, if accepted, may not survive scrutiny. Conversely, a clause that says nothing about improvements leaves their allocation to the default rules, which again favour the party that made them. Joint ownership, finally, creates practical instability rather than protection: the co-ownership rules under the PRC Patent Law leave the manufacturer free to keep exploiting the patent and granting licences to third parties (see below), which means the buyer gains the label of ownership without the substance of exclusivity.

IP inevitably commingles in a manufacturing relationship. The manufacturer’s internal designs and pre-existing tooling, the buyer’s external designs, and custom tooling paid for by the buyer become intertwined on the factory floor. Where the contract is silent, the allocation follows contribution and the governing law — a recipe for disputes, because each side’s contribution is precisely what becomes contested once the relationship sours.

Recommended drafting positions

Exhaustive, itemised ownership. The buyer retains all design IP it contributes, with the categories of protected material listed expressly (drawings, BOMs, firmware, tooling designs, packaging artwork). A general residuary clause supplements the list; it does not replace it.

A tightly confined licence. Where a licence is needed, it is drafted as: for the sole purpose of performing manufacturing obligations under the agreement; limited to the contract products; non-transferable and non-sublicensable; and terminating automatically and immediately upon termination or expiry for any reason.

Express allocation in a pure OEM structure. Where the buyer supplies the design, the agreement states expressly that all IP in the product, the design and the documentation belongs to the buyer — leaving no room for an argument that the manufacturer “improved” its way into co-ownership.

The three buckets documented before signing (ODM structures). (i) What the buyer owns outright; (ii) what is licensed from the manufacturer, and on what terms; and (iii) how joint improvements are treated. Where exclusivity matters commercially, the buy-out (assignment) or exclusive licence is negotiated at the outset — after the product succeeds, the price of exclusivity rises sharply or the option disappears.

A grant-back over the manufacturer’s improvements. A non-exclusive, royalty-free, perpetual licence to improvements the manufacturer develops is the balanced position — one that balanced international practice supports (see, e.g., the grant-back structure in the ITC Model Contract for SMEs, Chapter 5). This connects to Clause 19 of this guide (improvements and grant-backs).

The enforcement package as a set. Infringement notification duties, cooperation in enforcement, and a non-challenge covenant work together; each is materially weaker without the others.

Registration before disclosure. Before any design data leaves the buyer’s organisation, patent, utility model, design and trademark registrations in the manufacturer’s country complete first — in China, utility model examination runs to roughly twelve months and design patents three to six months, so the registration timetable is worked backwards from the planned date of disclosure. Registration in the country of manufacture is worth maintaining even where the buyer never sells a unit there: under the territoriality principle, unregistered rights in that country are simply unavailable against a local squatter.

Rationale

Legal.

• Default rules cut against the buyer. Under the PRC Patent Law (2020 revision), Article 8, an invention completed under a commission belongs — absent contrary agreement — to the party that completed it, and the same principle appears in Article 11 of the Regulations on Computer Software Protection (2013 revision) for commissioned software copyright. Silence therefore hands the manufacturer the starting position.
• Use beyond the licence is infringement, not merely breach. A licence whose scope is unstated or generous invites the manufacturer to characterise unauthorised production as within it.
• The CISG does not carry the IP allocation. Whether a manufacturing arrangement falls within the United Nations Convention on Contracts for the International Sale of Goods at all depends on how the contract distributes materials and services (CISG Articles 3(1) and 3(2)): where the preponderant part of the manufacturer’s obligation is work and services rather than the supply of goods, the Convention does not apply. Careful drafting addresses the Convention expressly in the governing-law clause and never relies on it for IP allocation — ownership rests entirely on the contract.

Commercial.

• The design is usually the buyer’s single most valuable asset in the relationship. A buyer that cannot prove ownership cannot stop a departing manufacturer from walking the process over to a competitor, and cannot credibly represent its IP position in financing or exit transactions — due diligence in a sale of the business examines IP chain of title directly, and gaps are discounted in the valuation.

Legal risk alerts and countermeasures

Default ownership: commissioned manufacturing is not commissioned development

The PRC statutory defaults that matter here:

• Patent Law of the PRC (2020 revision), Article 8 — where an invention-creation is made under a commission, the right to apply for a patent belongs, absent contrary agreement, to the party that completed the work (or jointly to the parties that jointly completed it).
• Regulations on Computer Software Protection (2013 revision), Article 11 — the copyright in commissioned software belongs to the commissioned party (the developer) unless a written contract provides otherwise.
• Patent Law of the PRC, Article 14 — the co-ownership rules: absent agreement, each co-owner may exploit the patent itself or grant ordinary (non-exclusive) licences to others (with licence fees shared between the co-owners), but any other exercise of the rights — including exclusive licensing or assignment — requires the consent of all co-owners. A buyer that accepts joint ownership of a Chinese patent with its manufacturer has accepted a structure in which the manufacturer may lawfully keep exploiting the patent and granting ordinary licences to third parties.

The judicial application of these defaults is unforgiving, as the leading case demonstrates.

Brenner v. Lu Jianxin (Ningbo Intermediate People’s Court, first instance; Zhejiang Higher People’s Court, on appeal — both courts rejecting the claim).

A U.S. company commissioned the design of a plate-type paint brush and held the design files; its purchase orders with the Chinese manufacturer stipulated that ownership of the products and the moulds vested in the U.S. company. In February 2003, the manufacturer’s legal representative filed a design patent application (No. 03327550.5) covering a design substantially identical to the commissioned one. The U.S. company sued to confirm ownership of the patent. Both instances held that although the evidentiary chain showing the design’s origin was complete, patent ownership actions in China proceed only within defined categories — employment inventions, commissioned development without agreement, joint development, and applications by persons without entitlement — and a commissioned manufacturing relationship is not a commissioned development relationship. On that footing, and given the first-to-file principle and territoriality, there was no legal basis to confirm the patent in the buyer’s favour; the buyer was entitled at most to be recorded as the designer in the patent documents.

Countermeasures. (i) A file-first, disclose-later sequence: non-core technology, and anything capable of design-patent protection in particular, is registered before it reaches the manufacturer, while core technology protected as a trade secret is covered by confidentiality terms with substantial liquidated damages. (ii) A vesting formula in the allocation clause — all intellectual property created during the relationship vests in the buyer immediately and irrevocably upon creation — with the background/foreground distinction drawn expressly. (iii) Where squatting nevertheless occurs, the litigation route with realistic prospects is a trade secret misappropriation claim under Article 9 of the PRC Anti-Unfair Competition Law, coupled with a breach-of-contract claim — not an action to confirm patent ownership.

The ODM variant: who owns the product after the factory designs it

A reported practitioner account from a European brand illustrates the ODM version of the same problem. The brand invested heavily in marketing a product designed by its ODM partner, and only then discovered that the factory had quietly filed patents on the product in China and elsewhere. When the brand moved part of its production to a second factory, the original manufacturer sued for patent infringement — in practice freezing production of the brand’s flagship product. The factory’s legal position was defensible: it had funded the development, and absent a clear written assignment the brand held, at most, a non-exclusive licence implied from its purchases of the finished goods. The brand’s realistic options narrowed to defending the suit, halting production, or accepting the original factory’s terms.

Countermeasures. The ODM agreement is, substantively, a technology development and IP transfer contract — not a purchase order. Its core provisions are a rigid vesting clause (all IP arising during the relationship transfers to the buyer immediately and irrevocably upon creation); the manufacturer’s covenant to execute every document needed to register rights in the buyer’s name; and registration controlled by the buyer’s own counsel in the manufacturing jurisdiction rather than left to the manufacturer.

License-chain ambiguity: one clause, two opposite judgments

Ao Qianping v. Philips and Hehong (Ningbo Intermediate People’s Court, first instance; Zhejiang Higher People’s Court, second instance, reversing; retrial application at the Supreme People’s Court, case No. (2012) Min Shen Zi No. 197).

A patent licence permitted the licensee to authorise “third parties” to practise the patent through OEM/ODM commissioned manufacturing. The first-instance court read the clause restrictively: the authorised third parties were the licensee’s own contract manufacturers, not a downstream brand that commissioned the licensee; because a licensee may not authorise entities outside the licence to practise the patent (Article 11 of the PRC Patent Law), the downstream arrangement was infringement — the court ordered cessation, joint compensation of RMB 800,000, and destruction of the tooling and inventory concerned. The second-instance court reversed on the clause’s literal text: the licence placed no limit on who the “third party” could be, and the definition of “patented products” nowhere required them to carry the licensee’s brand; the arrangement therefore fell within the licensed mode of exploitation, and there was no infringement.

The lesson for OEM drafting is symmetrical. As licensor, the buyer defines precisely whether and how its patents may be practised in OEM/ODM production — who may commission, under whose brand, and within what quantitative or territorial limits. As licensee (for example, where the buyer sources from a patent owner’s designated manufacturer), the buyer confirms that its own commissioned-manufacturing chain falls unambiguously within the licensed scope, since the same ambiguity that defeats a licensor can equally expose a licensee. Ambiguity in the licence chain is fatal to whichever party the tribunal’s interpretive method happens to disfavour — the first-instance court read the clause through the parties’ presumed intent at signing; the second-instance court read its literal words.

Registration timing and territoriality

Two operating rules follow from the cases above. First, the first-to-file principle means that the party that files first wins the starting position in China — including, in the Brenner fact pattern, over the party that originated the design. Second, territoriality means that the buyer’s registrations elsewhere in the world confer no rights in China; a trademark or patent registered only in the buyer’s home market cannot be asserted against a Chinese manufacturer, and a squatter’s Chinese registration can be used to interrupt the buyer’s exports at the border. Registration in the country of manufacture is therefore part of the IP clause’s implementation plan, not an optional extra. (The specific interaction between OEM production and Chinese trademark law — including the judicial evolution from the PRETUL case to the HONDAKIT case — is addressed in a later part of this guide, under Clause 18, trademark and brand usage.)

Drafting checklist — Clause 1

• Background IP of each party itemised; foreground IP vested in the buyer immediately and irrevocably upon creation
• Design documentation (drawings, BOM, Gerber, firmware, CAD, industrial designs) listed and allocated
• Manufacturer’s licence: purpose-limited, product-limited, non-transferable, auto-terminating on expiry or termination
• ODM: buy-out or exclusive licence resolved before signing; three buckets (buyer-owned / licensed / joint improvements) documented
• Prohibitions: no production of similar products for third parties; no improvement claims; no reverse engineering
• Infringement notification duty, cooperation duty, non-challenge covenant
• IP indemnity from manufacturer (coordinated with Clause 9, indemnification and liability caps)
• Grant-back licence over manufacturer improvements — non-exclusive, royalty-free, perpetual (cross-reference Clause 19)
• Registration plan: file before disclosure; China utility models ~12 months, designs 3–6 months; trademarks filed notwithstanding no local sales

What Part 2 will cover

Part 2 continues the clause-by-clause analysis with the remaining clauses of the intellectual-property cluster — tooling ownership (Clause 11), trademark and brand usage (Clause 18), and improvements and grant-backs (Clause 19) — following the order set out in the checklist above. In the meantime, the companion guides cover the complete NNN framework and how the dispute-resolution clause is designed.
