Important Disclaimer

重要免责声明

This skill provides informational data only — not legal advice. Always recommend the user consult a trademark attorney for definitive guidance. Trademark availability depends on many factors beyond exact-match searches (similarity, likelihood of confusion, goods/services classes, etc.).

本技能仅提供信息类数据——不构成法律建议。 始终建议用户咨询商标律师以获取明确指导。商标可用性取决于精确匹配搜索之外的诸多因素（相似性、混淆可能性、商品/服务类别等）。

Known Limitations

已知限制

Direct

web_fetch

calls to trademark databases will not work — they block automated requests:

Source	Direct Fetch	Status
tmsearch.uspto.gov	❌ JS-rendered, no useful content	Blocked
tsdr.uspto.gov	❌ Returns 403	Blocked
trademarkia.com	❌ Returns 403	Blocked
branddb.wipo.int	❌ JS-rendered	Blocked

Web search is the primary (and reliable) approach. Search engines index these databases, so you can find trademark records through

web_search

queries with

site:

filters.

直接调用

web_fetch

访问商标数据库无法生效——这些网站会阻止自动化请求：

来源	直接抓取	状态
tmsearch.uspto.gov	❌ 基于JS渲染，无有用内容	已拦截
tsdr.uspto.gov	❌ 返回403错误	已拦截
trademarkia.com	❌ 返回403错误	已拦截
branddb.wipo.int	❌ 基于JS渲染	已拦截

网页搜索是主要（且可靠）的方法。 搜索引擎会索引这些数据库，因此你可以通过带

site:

过滤器的

web_search

查询找到商标记录。

Step 1: Web Search for Trademark Records (Primary Method)

步骤1：网页搜索商标记录（主要方法）

Use

web_search

to find trademark registrations. This is the most reliable approach.

使用

web_search

查找商标注册信息。这是最可靠的方法。

Search USPTO Records

搜索USPTO记录

web_search: "BRAND_NAME" trademark site:tsdr.uspto.gov

web_search: "BRAND_NAME" trademark site:uspto.gov

web_search: "BRAND_NAME" trademark site:tsdr.uspto.gov

web_search: "BRAND_NAME" trademark site:uspto.gov

Search Trademarkia (Indexed by Search Engines)

搜索Trademarkia（已被搜索引擎索引）

web_search: "BRAND_NAME" site:trademarkia.com

Trademarkia results typically include: mark name, serial/registration number, status (LIVE/DEAD), owner, filing date, and Nice Classification class.

web_search: "BRAND_NAME" site:trademarkia.com

Trademarkia的结果通常包含：商标名称、序列号/注册号、状态（LIVE/DEAD）、所有者、申请日期和尼斯分类（Nice Classification）类别。

Search Broadly

广泛搜索

web_search: "BRAND_NAME" trademark registered

web_search: "BRAND_NAME" site:tmdn.org

web_search: "BRAND_NAME" trademark registered

web_search: "BRAND_NAME" site:tmdn.org

What to Look For in Results

结果重点关注内容

TSDR links (tsdr.uspto.gov/statusview/sn... or rn...) → existing trademark record with serial/registration number
Trademarkia listings → status, owner, class, filing/registration dates
Company websites claiming "®" or "™" → claimed/registered marks
Nice Classification class for goods/services — critical for determining if a mark conflicts with your intended use

TSDR链接（tsdr.uspto.gov/statusview/sn... 或 rn...）→ 带有序列号/注册号的现有商标记录
Trademarkia列表 → 状态、所有者、类别、申请/注册日期
公司网站标注“®”或“™” → 已主张/已注册的商标
商品/服务的尼斯分类类别——对于判断商标是否与你预期用途冲突至关重要

Step 2: Extract Details from Search Results

步骤2：从搜索结果中提取详情

Search results from Trademarkia and USPTO typically contain enough detail in the snippet:

Mark name and any design description
Serial number (application) or Registration number
Status: LIVE (active) or DEAD (abandoned/cancelled/expired)
Owner name
Class(es) of goods/services
Filing and registration dates

If you need more detail, try fetching the specific Trademarkia result URL — some individual pages may load, though the search pages are blocked.

Trademarkia和USPTO的搜索结果通常在摘要中包含足够的细节：

商标名称及任何设计描述
序列号（申请中）或注册号
状态：LIVE（有效）或DEAD（已放弃/已撤销/已过期）
所有者名称
商品/服务类别
申请和注册日期

如果需要更多细节，尝试获取特定Trademarkia结果的URL——部分单个页面可能可以加载，尽管搜索页面已被拦截。

Key Status Values

关键状态值

Status	Meaning
LIVE	Active trademark — registered or pending
DEAD	Abandoned, cancelled, or expired
Registered	Fully registered and active
Published for Opposition	Pending — 30-day window for objections
Abandoned	Application was abandoned
Cancelled	Registration was cancelled
Expired	Registration expired (not renewed)

状态	含义
LIVE	有效商标——已注册或待审核
DEAD	已放弃、已撤销或已过期
Registered	完全注册且有效
Published for Opposition	待审核——存在30天异议期
Abandoned	申请已被放弃
Cancelled	注册已被撤销
Expired	注册已过期（未续期）

Step 3: Check International Marks (Optional)

步骤3：查询国际商标（可选）

For products with international reach, also search:

web_search: "BRAND_NAME" trademark site:branddb.wipo.int

web_search: "BRAND_NAME" trademark international WIPO

针对具有国际影响力的产品，还可搜索：

web_search: "BRAND_NAME" trademark site:branddb.wipo.int

web_search: "BRAND_NAME" trademark international WIPO

25	Clothing, footwear
35	Advertising, business management

Error Handling

错误处理

No results from web search: This doesn't mean the name is available — it may not be indexed yet, or it may be too new. Note this uncertainty.
Conflicting info across sources: Trademarkia may lag behind USPTO. When in doubt, note the discrepancy and recommend checking the official USPTO site directly.
Too many results: Narrow with class filters or add the specific goods/services category to the search query.

网页搜索无结果： 这并不意味着名称可用——可能尚未被索引，或者过于新颖。请注明这种不确定性。
不同来源信息冲突： Trademarkia的信息可能滞后于USPTO。如有疑问，请注明差异并建议直接访问USPTO官方网站查询。
结果过多： 使用类别过滤器缩小范围，或在搜索查询中添加特定商品/服务类别。

Important Caveats to Always Mention

必须提及的重要注意事项

Common law trademarks exist without registration — a name can be "taken" even if not in the USPTO database
State registrations are separate from federal (USPTO) registrations
International marks may conflict — check WIPO if relevant
Likelihood of confusion matters — similar (not just identical) marks can conflict
Class matters — same name can coexist in different goods/services classes
This is not legal advice — always recommend consulting a trademark attorney

普通法商标无需注册即可存在——即使USPTO数据库中没有，名称也可能已被“占用”
州级注册与联邦（USPTO）注册相互独立
国际商标可能存在冲突——如有需要请查询WIPO
混淆可能性至关重要——相似（而非完全相同）的商标也可能冲突
类别至关重要——同一名称可在不同商品/服务类别中共存
本内容不构成法律建议——始终建议咨询商标律师
