IP Protection in China Sourcing
Trademark, design, and patent registration strategy โ€” the 10-stage system that keeps sellers from losing their brand at the OEM stage

Hello, this is GreenFrog Seoul.

"I built this brand for three years โ€” then someone in China registered the trademark first, and now I can't legally use it there."
"My OEM factory is selling my exact design to another seller. I complained โ€” they told me 'whoever sent the drawing is responsible.'"
"I have the patent in Korea, but Alibaba is full of identical products. Where do I even start?"

In China OEM, IP isn't "automatically protected because you have IP somewhere else." It's "a system the seller registers and operates inside China." Sellers with an IP system see counterfeit / copy rates under 5%; those without one see 40โ€“60%. The difference isn't the product; it's "who locked down rights inside China first."

Korean / US / EU IP is valid only at home. To be protected in China you must build a separate system: China trademark, China design patent, China invention/utility patent, China customs recordal.
A foreign certificate in your hand is just a piece of paper in the Chinese market.

Today we condense GreenFrog Seoul's 10-stage IP protection system โ€” refined over 7+ years on the ground with sellers โ€” onto one page. From China trademark pre-filing, Madrid filings, design patents (ๅค–่ง‚่ฎพ่ฎก), utility models, invention patents, NNN agreements, mold ownership, customs IPR recordal, counterfeit enforcement, to dispute response. Including where the seller's job ends and where Chinese trademark agents and law firms should pick up.


1. Why IP protection collapses โ€” the 5 structural gaps where sellers keep getting stuck

IP incidents in China OEM aren't "luck" โ€” they're "already-known system gaps." Sellers keep getting stuck in the same five places.

Structural gapExplanationStage that fixes it
No China trademarkTrusting only home-country registration โ†’ squatter takes itStages 2โ€“3: China TM, Madrid
No design patentOEM factory sells your design to others as their ownStage 4: Design patent
Late patent filingHome-country filing only, 12-month priority window missedStages 5โ€“6: Utility / invention
No NDA / NNNDrawings and molds leak to other sellersStage 7: NNN agreement
Unclear mold ownershipFactory uses your mold for other customersStage 8: Mold ownership
No customs / platform recordalNo authority to act, can't even start enforcementStages 9โ€“10: Customs, enforcement
โš ๏ธ "In China, IP belongs to whoever registered first โ€” your foreign registration has no effect" China is a "first-to-file" jurisdiction. A brand you've used for ten years at home is owned by whoever registers it in China first. Across 100+ sellers we've consulted, 23% had been pre-empted by a third party before entering China; the average recovery cost was USD 12,000โ€“40,000 with a recovery success rate under 35%. Your first task in China isn't the product โ€” it's IP registration.

2. Stage 1: IP asset inventory โ€” "list what you intend to protect first"

Every IP system starts with "what IP do we own?" Without an inventory, registration priority, budget allocation, and competitor response are all impossible.

Six things an IP asset inventory must include

Registration priority (Tier 1 / 2 / 3)

PriorityScopeExamplesFiling timing
Tier 1 (immediate)Core brand assetsPrimary trademark, lead-product appearanceBefore D-180 of OEM order
Tier 2 (within 3 months)Extension assets, seriesSub-brands, series designs, technical patentsBefore D-90 of first production
Tier 3 (within 6 months)Defensive, reservesChinese phonetic transliterations, similar marks, domainsBefore D-30 of launch
๐Ÿ’ก "One inventory blocks 100 disputes" A single spreadsheet is enough โ€” but it must include these six columns: "What is the IP / China registration status / registration number / expiry / shared with factory / next action." We provide every seller with an IP inventory template and run a quarterly refresh.

3. Stage 2: China trademark registration โ€” "Priority #1 in a first-to-file country"

China is first-to-file. The owner is "whoever registered first," not "whoever used it first." Korean, US, or international common-law marks have no effect โ€” you must file separately at the China National Intellectual Property Administration (CNIPA).

Three filing routes for China trademarks

RouteNotesCostRegistration time
Direct China filingThrough a Chinese agent at CNIPAUSD 500โ€“1,000 per class9โ€“12 months
Madrid international filingVia home IP office, multi-country at onceUSD 250โ€“400 per country12โ€“18 months
Hong Kong roundaboutHK filing first, then mainlandHK USD 400โ€“700 + ChinaInefficient (avoid)

Three rules for China trademark filings

โš ๏ธ "The better your brand sells abroad, the bigger the squatting target" China has dedicated "trademark squatters" who monitor brands trending in Korea / Japan / US / EU, register them in China, and resell to the original owner at entry time. Single-mark deals run USD 4,000โ€“40,000. Even with 0% China-entry intent, file your Chinese trademarks defensively. Filing cost: USD 500. Buyback cost: USD 12,000+.

4. Stage 3: Madrid international filings

The Madrid Protocol lets you file once at your home IP office and extend simultaneously to 130+ countries including China, the US, the EU, and Japan. For sellers, it's the core cost / time-saving tool.

Madrid pros and cons

AspectMadrid filingDirect China filing
CostUSD 250โ€“400 per country (~half)USD 500โ€“1,000 per class
ManagementUnified WIPO renewal / transferCountry-by-country admin
Registration time12โ€“18 months9โ€“12 months
Refusal handlingNeed separate Chinese agentChinese agent from day one
3-year dependencyHome invalidation cascadesIndependent right

Madrid vs direct โ€” recommendations by seller profile

๐Ÿ’ก "Madrid's real value is one-shot renewal and transfer" A seller with 10 separate national registrations renews 10 times at the 10-year mark. Madrid renews them all at once via WIPO. Same for company sales and license transfers. Over a 10-year horizon, Madrid is 50%+ cheaper than direct filings across multiple countries.

5. Stage 4: Design patent (ๅค–่ง‚่ฎพ่ฎกไธ“ๅˆฉ) โ€” "instant protection for product appearance"

China's "design patent" protects the visual design โ€” shape, color, pattern โ€” of a product. Because it's a formality-only registration with effect on grant, it's the #1 IP tool for OEM sellers.

Six properties of a Chinese design patent

Standard design-patent filing procedure

  1. Six-side photos / renders โ€” front, back, left, right, top, bottom + perspective
  2. Brief description โ€” 200โ€“500 character summary of design highlights
  3. File at CNIPA via Chinese agent โ€” direct filing is technically possible but not recommended
  4. Receive registration certificate in 4โ€“6 months โ€” registration number + PDF
  5. Use immediately for customs / platform recordal
โš ๏ธ "Never publish a design before filing" Novelty rule: any prior public disclosure โ€” social posts, trade shows, crowdfunding โ€” kills your application. A Kickstarter campaign before China filing destroys novelty. The order has to be: "home filing โ†’ file in China within 6 months under priority โ†’ only then publish."

6. Stage 5: Utility model (ๅฎž็”จๆ–ฐๅž‹ไธ“ๅˆฉ) โ€” "best price-performance for technology protection"

The utility model protects the structural / configurational technical solution of a product. Faster and cheaper than an invention patent, it's the most-used technical-protection tool by OEM sellers.

Utility model vs invention patent

AspectUtility modelInvention patent
ScopeStructure, configuration (products only)Structure, configuration, method, substance
ExaminationFormal onlySubstantive (prior-art comparison)
Time to grant6โ€“12 months2โ€“4 years
CostUSD 1,000โ€“2,000USD 2,500โ€“5,000
Term10 years20 years
StrengthMedium (invalidation risk)Strong

Common utility-model patterns for sellers

๐Ÿ’ก "Utility models are the OEM seller's 'rights in 6 months' tool" Invention patents take 2โ€“4 years to grant โ€” that's 2โ€“4 years of unprotected market while copies multiply. Utility models grant in 6โ€“12 months โ€” enabling counterfeit takedowns and customs recordal essentially the same time you start production. Invention patents act as the long-term backup. Filing both is the right ROI play.

7. Stage 6: Invention patent (ๅ‘ๆ˜Žไธ“ๅˆฉ) โ€” "long-term technical asset"

The strongest right, but the slowest and most expensive. Worth it only when there's real core technology. Filed wrong, you get the worst of both worlds: "published but never granted."

Three signals that invention-patent filing makes sense

Things to watch in invention-patent filing

Watch out forDetail
12-month home priorityParis Convention โ€” preserve home filing date as China filing date
PCT international filingUp to 30 months to decide on China entry โ€” buys time
Chinese specificationTranslation precision determines claim scope
Examination requestMust request within 3 years โ€” otherwise auto-withdrawn
Refusal response1st response โ†’ 2nd response โ†’ review board โ€” Chinese agent required
โš ๏ธ "Your home patent agent does NOT file in China" A non-Chinese patent attorney can only file in their own country. China filings legally require a licensed Chinese patent agent (ไปฃ็†ไบบ). If your home agent says "we'll handle China too," what's actually happening is that they sub-contract to a Chinese agent and add a markup. Sellers pay margin twice. We connect sellers directly to Chinese agency offices, cutting fees 30โ€“40%.

8. Stage 7: NDA / NNN agreements โ€” "the legal lock on drawings and molds"

The moment you send drawings, mold drawings, or BOMs to a factory, IP-leak risk begins. Western-style NDAs are nearly unenforceable in China โ€” what you actually need is an "NNN agreement (Non-Disclosure, Non-Use, Non-Circumvention)."

The three Ns

NNN vs Western-style NDA

AspectWestern NDANNN agreement
Governing lawMostly home-countryChinese law
JurisdictionMostly home courtChinese People's Court
LanguageEnglish / home languageChinese original + English copy
Penalty clauseAbstract "damages"Concrete (e.g., RMB 500,000)
Practical enforceabilityEffectively zeroDirect Chinese-court enforcement
Factory chopCorporate sealFactory ๅ…ฌ็ซ  (official chop)
โš ๏ธ "A foreign NDA is just paper in China" NDAs governed by foreign law / foreign court / English-only are practically unenforceable if the Chinese factory breaches. A real NNN must combine four elements: Chinese-language original + Chinese law + Chinese court jurisdiction + concrete monetary penalty. An NNN with the factory's ๅ…ฌ็ซ  (official chop) is the document Chinese factories fear most.

9. Stage 8: Mold ownership โ€” "the biggest physical IP asset in OEM"

A mold isn't just production hardware โ€” it's "the physical embodiment of the right to make this product." Without explicit mold ownership, factories sell off-the-mold to other sellers or run their own listings.

Locking down mold ownership in 4 steps

  1. Itemize mold cost in the PO โ€” e.g., "1 set tooling: USD 10,000"
  2. Mold ownership clause in the OEM contract โ€” explicit "mold ownership belongs to the seller"
  3. Mold photos, engraving, and serial numbers managed โ€” engrave seller's company name and serial onto the mold itself
  4. Right to take possession โ€” explicit right to remove the mold at end of relationship

Five mold dispute patterns

๐Ÿ’ก "One engraving line blocks 100 mold disputes" Require this engraving on the mold body: "OWNED BY [seller's company name] / SERIAL: [number] / [order year-month]". Cost: USD 50โ€“80. Effect: decisive โ€” supplying that mold to another seller becomes nearly impossible. We run mold engraving, photo, and serial as part of every OEM PO.

10. Stage 9: Customs IPR recordal (ๆตทๅ…ณ็Ÿฅ่ฏ†ไบงๆƒๅค‡ๆกˆ) โ€” "the weapon for stopping counterfeit exports"

Recording your IP with China Customs lets customs automatically intercept counterfeit shipments. The recordal is free โ€” yet under 10% of foreign sellers actually use it.

Three effects of customs recordal

Recordal procedure

StepDetailTime
1. EligibilityMust hold a registered Chinese trademark / patent / design patent-
2. ApplicationOnline via the China Customs IPR system1โ€“2 days
3. Submit materialsRegistration cert, product photos, genuine-vs-fake guide1 week
4. Review and recordalGeneral Administration of Customs reviewWithin 30 days
5. Validity 10 yearsWithin IP term, renewableRenewable
โš ๏ธ "Without customs recordal, you watch counterfeits leave China and arrive at your home market" Without recordal, you only learn about counterfeit exports after they reach Korea / US / EU โ€” by then recovery cost is overwhelming. Recordal is free; doc-prep cost is around USD 400โ€“500. For sellers holding a Chinese trademark or design patent, recordal is 100% recommended.

11. Stage 10: Counterfeit and copy enforcement โ€” discovery to action

Once a counterfeit appears, the seller's decision window is short. You need a "discover โ†’ evidence โ†’ take down โ†’ trace" system already in place.

Standard 5-step enforcement

  1. Discovery channels โ€” Alibaba, 1688, Taobao, Amazon, eBay monitoring
  2. Evidence preservation โ€” page captures, test purchases, lot numbers, shipper records
  3. Platform takedown โ€” Alibaba IPP, Amazon BPP, Taobao Rights Protection
  4. Customs enforcement โ€” request detention based on recorded IP
  5. Legal action โ€” administrative enforcement (AMR) or civil litigation

Platform takedown systems

PlatformSystem nameOnboardingTakedown speed
Alibaba / 1688IPP (IP Protection Platform)15โ€“30 daysFast (3โ€“7 days)
Taobao / TmallRights Protection system15โ€“30 daysFast (3โ€“7 days)
AmazonBrand Registry + BPP2โ€“14 daysMedium (1โ€“4 weeks)
PinduoduoIPR protection platform15โ€“30 daysMedium (1โ€“2 weeks)
XiaohongshuBrand Owner status30 daysMedium
โš ๏ธ "One ignored counterfeit becomes 100" The moment you see one counterfeit, 50 more are already in the works. Without immediate takedown, that category's counterfeits multiply 10โ€“50ร— within a month. We run weekly Alibaba / 1688 monitoring and file takedowns under the seller's name on discovery. Self-filed takedowns get bogged down in Chinese-language documentation; mediated handling is overwhelmingly more efficient.

12. GreenFrog Seoul's IP mediation service

The 10-stage IP system above sits between "too heavy for a seller alone" and "too one-shot to leave to a Chinese law firm." GreenFrog Seoul runs the full system from the seller's side via 7+ year on-the-ground Korean consultants.

What this service changes

๐Ÿ’ก "IP isn't a cost โ€” it's a lifelong brand asset" IP filing fees are one-time and spread over 1โ€“3 years. But buying back a single squatted Chinese trademark costs USD 12,000โ€“40,000; one year of unaddressed counterfeiting averages 30โ€“50% in lost revenue โ€” IP-system ROI clears 100ร— in year one. The bigger value is "insulating your brand from external variables" โ€” every marketing, expansion, and exit decision becomes cleaner.

Wrap-up โ€” IP isn't luck, it's a system

Compressed to one line each, the 10 stages:

IP in China OEM isn't "protected automatically by your home filings" โ€” it's "a system the seller registers and operates inside China." The same product yields under 5% counterfeit incidence to a seller with the system, and 40โ€“60% to a seller without it. GreenFrog Seoul builds the IP system from inventory through quarterly operation, all the way through enforcement when copies appear. If you're preparing to enter China, or already running OEM but with IP unsorted, feel free to reach out.
