Search public trademark records associated with a Chinese company by legal name, unified credit code, registration number, or former name.
This tool searches public trademark records associated with a Chinese company. Enter a legal company name, Unified Social Credit Code, business registration number, or former company name to retrieve paginated records through the bound OpenAPI Product. A result may include the mark name, application or registration number, Nice class, application date, reported public status, and an image URL. It is useful for preliminary due diligence, brand-portfolio reviews, competitor research, and checking information supplied by a business partner.
The search answers a company-centred question: which trademark records may be connected to this legal entity? It does not decide whether a new mark can be registered, prove ownership, or provide a legal-status certificate. Source update cycles, spelling variants, entity renaming, and ownership transfers can affect the result set, so treat each record as a research lead that still requires verification.
Use the full legal name printed on the company registration document whenever possible. A brand, store name, product name, or shortened company name can match the wrong entity or return no records. If the company has changed its legal name, search both its current and former names. When names are common, a Unified Social Credit Code or registration number is usually a more precise identifier.
Do not add quotation marks, comments, URLs, or contact details to the search field. The page displays a fixed number of records per request. Moving to another page sends a new paid request and charges the coin amount shown by the tool. If no result appears, check Chinese characters, company suffixes, administrative-region wording, whitespace, and historical names before trying again.
The trademark name identifies the word, device, or combined mark recorded by the source. A number may represent an application or registration number depending on the procedural stage. The Nice class groups goods and services; identical wording can be owned by different parties in different classes. The application date indicates when the filing was submitted, while the status is the source's latest reported public description. An image URL can help distinguish device and composite marks.
Several similar records are not automatically duplicates. A company may file the same mark in several classes, submit revised artwork, or make separate applications over time. Conversely, an empty result does not prove that the company has never filed a mark. The data may still be synchronising, a transfer may not yet be reflected, or the mark may be registered under a related legal entity.
For supplier due diligence, search the supplier's exact legal name and compare the returned marks and classes with the brands it claims to operate. For competitor analysis, group records by Nice class and application date to observe product, service, and defensive filing patterns. For an internal IP inventory, query both current and former company names and compare the results with records maintained by legal counsel or a trademark agency.
When a result contains a similar but not identical applicant name, do not assign it to the target business without further checks. Verify the company identifier, registration details, applicant information, and official notices. Parent companies, subsidiaries, operating companies, and former entities are separate legal persons and should normally be searched individually.
First confirm that the input is a legal entity name rather than a consumer-facing brand. Remove unnecessary spaces and verify suffixes such as the Chinese equivalents of limited company or joint-stock company. Search a former name if the entity has been renamed, and prefer the Unified Social Credit Code when available. If the response reports many records, review later pages before estimating the size of the portfolio.
If the upstream service times out, rejects a request, or omits expected fields, the interface reports an error instead of presenting an empty response as a verified conclusion. Avoid rapid duplicate submissions because each successful request may incur a charge. For important decisions, use the registration number to verify the latest notices and procedural events through the official CNIPA public system.
Appropriate uses include early-stage corporate research, partner screening, brand-asset inventories, competitor mapping, and collecting references before a professional trademark search. The tool is most effective as a first step that turns a company identifier into a manageable list of potentially relevant trademark records.
It is not suitable for deciding registrability, similarity, infringement, validity, ownership disputes, or freedom to operate. It does not replace an official file, a certified record, legal advice, or a qualified trademark professional. Applications, licences, assignments, pledges, oppositions, invalidation proceedings, litigation, and high-value transactions require current official evidence and professional review.
Results come from a third-party public-information API and may differ from official records in update time, terminology, and field coverage. Every query and page change can be billed at the current tool price, so review the search term before submitting. The tool does not require an image of a business licence or personal details such as a phone number, identity number, or bank-card number.
Enter only a public company name or business identifier. Do not append contracts, passwords, account data, personal contact details, or other sensitive information. Use the results only for lawful research and verification. Record the query date, exact input, and important registration numbers so that findings can be reproduced and checked later.
