GleanMark USPTO Trademark Search

Analyze the full prosecution history of a trademark — narrative timeline of office actions, responses, examiner decisions, and current status, with examiner-behavior patterns. For authenticated users this launches asynchronously (usually done in under a minute; longer for large file histories) and returns a processing handle used to retrieve the completed result once ready.

Analyze a TTAB (Trademark Trial and Appeal Board) proceeding in depth — fetches and analyzes proceeding documents, identifies key arguments, and returns a structured summary with timeline, party positions, and strategic assessment. For authenticated full-mode runs this launches asynchronously (typically 1-2 minutes) and returns a processing handle used to retrieve the completed result once ready.

Quick brand-name screen: checks whether the name's domains are registered and whether the .com site is in use, looks for similar registered trademarks in the given industries or classes, and returns a screening tier (avoid, probably avoid, promising, or no close conflicts surfaced) with the top conflicts and a domain snapshot. It is a first look, not a clearance search: it does not cover common-law use, state registrations or a full goods-relatedness analysis, so a result with no conflicts means none surfaced in this screen, not that the name is available. run_knockout_search is the fuller trademark conflict search.

Check domain availability for a brand name. Returns status (available, parked, commercially used, or taken) for each TLD, plus .com variations (e.g., getbrand.com, brandhq.com).

Compare two trademarks for likelihood of confusion using DuPont-style analysis. Returns similarity scores and risk assessment.

Counts U.S. trademark applications filed across the whole register in a date range, grouped by calendar year, month or day, with each period split into U.S.-filed and Madrid Protocol (79-series) applications and the change from the previous period. Answers questions such as how many trademark applications were filed in 2025 and how that compares with 2024, or which month of a year had the most filings. Counts are one per serial number by the filing date on the USPTO record; they are calendar periods, not USPTO fiscal-year statistics, and not class counts. Returns data_through, the latest filing date on the register; recent periods grow as late records arrive.

Counts and previews USPTO marks by record attributes (drawing type, standard-character claim, Nice class, status, and combinations of these), with breakdowns by mark type, standard character and class, plus how complete the underlying data is. Claimed-color criteria can be combined with these attributes; counts by color alone, rankings, lists and color vocabulary are outside its scope.

Retrieve the full USPTO record for one trademark, using an id returned by the search tool. Returns mark, owner, status, filing and registration dates, Nice classes, the goods and services text, and counsel of record, with a public gleanmark.com URL for citation.

Traces who has owned a trademark over time: the ownership stages the USPTO recorded, from the original applicant or registrant through each later owner, plus any recorded assignment documents GleanMark holds. Answers questions such as who owns a mark now versus who filed it, whether it was sold, transferred or assigned, and how it reached its current owner, including chain-of-title and due-diligence questions. lookup_trademark shows only the current owner. Owners listed within one stage are joint owners, not successive ones. Not a title opinion.

Look up coordinated Nice classes or related Nice classes for a given class number.

Measures the time between two prosecution events across a group of marks, e.g. the average days from Office Action to publication for marks published in Q2 2026. The group is chosen by an anchor event (preset: publication, notice_of_publication, registration, notice_of_allowance, abandonment or first_office_action, or raw event codes, where a trailing * matches a prefix) within a date window of up to 366 days; the interval runs from a start event to an end event. Returns the average, median and percentiles in days, how many marks in the group had no start event, and example marks. Samples up to max_sample marks from the start of the window and says when the sample is truncated. Event codes beyond the presets are listed by get_event_code_reference.

Get all trademarks handled by a specific attorney/correspondent, with prosecution event counts and office action flags. Returns marks sorted by prosecution history length. Use this for attorney-specific mark queries.

Summarize what a named correspondent specializes in, including top clients, top Nice classes, and prosecution-versus-TTAB profile. Use this when the user asks what a specific correspondent or attorney specializes in.

Check what role a USPTO event code plays for a deadline type (satisfies it, triggers it, abandons it, suspends it) per the deadline vocabulary table deadline_event_roles — office action response, opposition period, Statement of Use, Section 8/9/15, post-registration office action, ITU notice.

Look up USPTO event codes used in trademark prosecution. Search by exact code, code prefix, or keyword in the event description. Returns the code, human-readable description, and category.

Look up which USPTO status code and status definition most commonly follow a specific prosecution event code.

Get the full fame profile for a brand (by mark wording or brand stem): fame tier (broad/dilution-tier vs market-specific), the fame "path" it cleared (concentrated dominant family vs large multi-class portfolio), its famous class footprint, corporate-family portfolio size and class breadth, brand-stem crowding, and TTAB enforcement history. Use to explain WHY a mark is (or is not) famous, or to profile a senior mark before a §2(d) / opposition / dilution strategy. Circumstantial signal, not statutory fame proof.

Resolves a trademark law firm and returns its action-required work: overdue deadlines and those in the next window, plus recent Office Actions from case-file events and prosecution documents, with flags for a filed response and for Section 2(d) refusals. Answers questions such as which correspondent tasks a firm has in the next 30 days or which recent Office Actions a firm has received.

Get public, system-generated trademark deadlines across marks handled by a specific law firm. Uses public firm resolution and prosecution mappings only. Does not expose any workspace, client, reminder, or user-created deadline data.

Resolve a trademark law firm and compute mark-level Office Action outcome rates: how many firm-handled marks registered after receiving an OA, raw and excluding pending matters. Use this for questions like "what percentage registered after an OA?" or "OA success rate for this firm".

Ranks the correspondents or attorneys within one named law firm by filing volume, with prosecution and TTAB activity counts. Answers questions such as who the top correspondents at Fross Zelnick Lehrman & Zissu are.

Returns the most recent Office Action for a trademark serial number, the latest recorded response if there is one, and the refusal grounds parsed from the Office Action text, with the cited registration numbers. refusal_grounds is taken from the text of the action, not from the document title.

Get an AI-generated deep-dive summary of a specific trademark. Covers mark details, goods/services, status, owner, prosecution context, and any active legal proceedings.

Get public, system-generated trademark deadlines for a specific mark. Accepts a serial number directly or resolves a mark name to a specific serial first. Does not expose any workspace, client, reminder, or user-created deadline data.

Get the international / foreign footprint of a U.S. trademark by serial number: its Madrid Protocol international registration (IR number, date, status, renewal), whether it was filed as a 66(a) Madrid extension, Madrid maintenance (§8/§15, renewal), and the foreign applications/registrations it claims as priority or basis (country, registration number, dates). Use this for ANY question about a mark's foreign, international, Madrid Protocol, WIPO, or EUIPO registrations. Data comes from USPTO records, so it is only available for marks with a USPTO record — it does not query WIPO/EUIPO live.

Show which owners hold marks matching a shared trademark term and summarize what else those owners have in their broader portfolios. Use this for crowded owner-landscape questions like "Which companies own a trademark for COMET?" or "Who owns trademarks for GLEAN?" Returns the matching owners ranked by footprint, with each owner's wider portfolio context.

Get a compact prosecution summary for a trademark serial number. Returns current status, document counts, latest office action/response dates, milestones, and the latest key event.

Get information about Nice Classification classes used for trademark registration. Lookup specific class numbers or search for classes by keyword.

Get an AI-generated strategic analysis of a trademark owner. Covers brand protection philosophy, litigation posture, portfolio evolution, class distribution, and likely future behavior. Results are cached for 30 days.

Get public, system-generated trademark deadlines across a specific owner’s marks. Uses public USPTO owner resolution only. Does not expose any workspace, client, reminder, or user-created deadline data.

Get a trademark owner's filing trends over time — yearly filing counts broken down by Nice class. Shows how the owner's trademark portfolio has evolved.

Get the most frequent goods/services keywords for a trademark owner. Shows what products and services the owner focuses on, useful for understanding their brand strategy and identifying class patterns.

Find entities likely related to a trademark owner (predecessors, subsidiaries, sister companies) from USPTO evidence: shared ownership history on the same marks, shared filing addresses (agent addresses excluded), and shared distinctive name tokens. Returns evidence and a high/possible confidence tier per hit — treat 'possible' as tentative. Use when analyzing an owner's full corporate family, portfolio scope, or whether two owners of similar marks are actually affiliated. Pass the owner name exactly as recorded (resolve with resolve_trademark_subject first if ambiguous).

Analyze one trademark owner's TTAB enforcement in a single call. Filters and counts only target marks that actually satisfy the requested class, mark-type, and claimed-color criteria; separately reports all targets attached to qualifying proceedings. Supports exact class-only questions with target_class_match=only. Claimed-color metadata identifies candidate marks but does not prove color was alleged in the pleading; use analyze_ttab_proceeding for that evidence.

Returns a compact TTAB history for one owner: counts of inter partes proceedings, oppositions, cancellations, extensions of time to oppose and appeals, broken down by the owner's role. The total counts every record, including extensions and cases the owner defended, so it is not the number of oppositions the owner started. get_owner_ttab_enforcement covers date ranges and the marks and classes challenged.

Retrieve one specific USPTO prosecution document by the stable document_id returned from list_prosecution_documents, USPTO document id, code, or date. Returns the working USPTO document link, extraction/readability status, cached document text, and optional query-centered excerpts. Use text_query when the user asks what the document says about a particular issue. Call with serial_number alone and it returns the list of documents on file (newest first) so you can pick one — no separate list_prosecution_documents call needed.

Get the prosecution timeline for a trademark — chronological list of office actions, responses, and key events (publication, registration, suspension, etc.). Raw data without AI analysis.

Look up USPTO or TTAB reference codes and small lookup tables such as status codes, statement types, legal entity types, Nice classes, design codes, and TTAB proceeding/status/role codes.

Find USPTO trademarks similar to a given mark name. Uses examiner-style knockout search with phonetic, trigram, and component matching to identify potential conflicts. Returns similarity_score (mark-only similarity) and confusion_score (blended mark + commercial overlap). Useful for trademark clearance searches.

Get a ranked filer table for a date range, filer type, and optional Nice classes. Handles questions like "Who are the top 10 filers in Class 9 in 2025?" Returns ranked rows with per-filer live, registered, and pending counts plus corpus totals. A single call covers the full ranked list: `limit` (up to 100) sets the number of rows and the date range may span multiple years. `offset` reaches ranks beyond 100 or a specific band (ranks 40-45 = `limit: 6, offset: 39`).

Retrieve and read one specific TTABVUE filing by proceeding number and entry number. Returns filing metadata, a working USPTO TTABVUE viewer link, direct PDF link when available, extraction/readability status, document text, and optional query-centered excerpts. Use get_ttab_proceeding_details first when the entry number is unknown.

Get raw details for a TTAB proceeding — parties, involved marks, counsel, and recent filings with entry numbers and working TTABVUE document links. Use get_ttab_document to read one selected filing. Use get_owner_ttab_enforcement for owner-wide distributions and analyze_ttab_proceeding for AI-powered merits analysis.

Ranks the parties that filed the most TTAB oppositions (or cancellations) across the whole Board in a date range. Answers market-wide questions such as which party filed the most oppositions in April 2026. Takes a calendar date range. One owner's record is covered by get_owner_ttab_stats, and one proceeding by get_ttab_proceeding_details.

Checks whether a trademark is famous, and whether it is famous for a specific market, using the applicant's Nice class as a stand-in for that market (fame is market-specific under Joseph Phelps Vineyards v. Fairmont: a mark famous for electronics is not automatically famous for fresh fruit). Returns is_famous, famous_in_class, the fame tier (broad household-name fame or market-specific fame), the classes where the mark is famous, portfolio size, and the corporate family's record as a TTAB plaintiff. Relevant to whether a mark is famous, the strength of a senior mark under Section 2(d), and dilution eligibility under Section 43(c). A circumstantial signal, not proof of statutory fame.

List prosecution documents for a trademark serial number, including stable document identifiers, working USPTO links when available, extraction/readability status, office actions, responses, notices, and other dated filings. Use get_prosecution_document to read one selected document.

Get detailed information about a specific USPTO trademark by its serial number. Returns owner, status, filing dates, goods/services, correspondent (attorney/law firm of record — use this for "which firm represents/is correspondent for" questions), and more.

Finds trademarks whose whole mark sounds like the given mark, using Metaphone codes and trigram similarity with a whole-mark threshold. Because it compares entire marks, a multi-word mark that only contains a sound-alike word is not returned: for QUICK, KWIK REWARDS does not appear even though KWIK sounds like QUICK. An empty or short result does not show that no sound-alike marks exist and is not a clearance result; run_knockout_search is the conflict search.

Recommend Nice trademark classes based on a business description. Returns the most relevant classes with confidence scores and explanations.

Research the Office Action for a trademark — returns structured refusal categories, latest OA/response context, cited marks, and third-party registrations that support coexistence arguments. For authenticated users this launches asynchronously (typically 1-2 minutes) and returns a processing handle used to retrieve the completed result once ready.

Matches a name to one trademark entity (an owner, law firm, correspondent, mark, TTAB proceeding, client or portfolio) and returns the match with its identifiers, or the top candidates when the name is ambiguous. Resolving clients and portfolios requires a signed-in account.
