VietnamTrademark

VietnamTrademark connects Claude to the VietnamTrademark.net database of trademark applications and registrations in Vietnam, compiled from the Intellectual Property Office of Viet Nam (IP Viet Nam) and the Industrial Property Official Gazette and updated with each gazette issue. With it, Claude can: Look up a trademark by name, application number (4-YYYY-NNNNN) or registration number: status, owner and address, IP representative, Nice classes, goods/services, filing/registration/expiry dates, prosecution history and mark image. Search for identical or similar marks before filing, using Lucene syntax (phrases, wildcards, fuzzy matching), Nice class filters, related classes and goods/services keywords. List an owner's or representative's portfolio and follow new filings, registrations, Madrid designations, assignments, renewals and corrections published in Gazette Volumes A and B. Look up the 45 Nice classes with their related classes and the four normalized statuses 'Cấp bằng' (registered), 'Đang giải quyết' (pending), 'Từ chối' (refused) and 'Hết hiệu lực' (expired/withdrawn). Every record includes a link to its page on VietnamTrademark.net. Trademark data, field labels and tool messages are in Vietnamese; the prompts ask Claude to answer in the user's language. All tools are read-only. Using the tools requires a VietnamTrademark.net account with an active API plan; reference lookups do not count toward the quota. Results reflect the official records at the time of the call and are not legal advice.
