GleanMark 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 SCREEN — combines domain availability with a trademark conflict signal for the industries given. NOT a clearance search and NEVER an availability answer: it does not see common-law rights, state registrations, or goods relatedness in any depth. Returns a screening tier (avoid, probably avoid, promising, or nothing surfaced). Report a clean result as "our quick search did not surface close conflicts" — never as "no conflicts", "available", or "clear" — and always point the user to a complete clearance search. Availability conclusions come only from run_knockout_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.

Count and preview USPTO marks by record attributes rather than owner identity, with mark-type, standard-character, and Nice-class breakdowns plus metadata coverage. Use this for drawing type, standard-character, Nice-class, status, and cross-attribute counts. It can intersect claimed-color criteria with those attributes; color-only counts, rankings, lists, and 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.

Trace who has owned a trademark over time — the ownership stages USPTO recorded (original applicant/registrant through each successive new owner), plus any recorded assignment documents we hold. Use this whenever the user asks who owns a mark now versus who filed it, whether a mark was sold, transferred or assigned, how it came to its current owner, or for chain-of-title / due-diligence questions. lookup_trademark returns only the CURRENT owner and cannot answer any of these. Owners listed within a single 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.

Aggregate event-to-event pendency across a COHORT of marks — e.g. "average days from office action to publication for marks published in Q2 2026". Pick the cohort by an anchor event (preset: publication, notice_of_publication, registration, notice_of_allowance, abandonment, first_office_action — or raw event codes, trailing * = prefix) within a date window (max 366 days), and an interval start/end event. Returns avg/median/percentiles in days, how many cohort marks never had the start event, and example marks. Samples up to max_sample marks from the start of the window and says so when truncated. Use get_event_code_reference first if you need non-preset event codes.

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.

Resolve a trademark law firm and return what its lawyers should focus on: overdue/next-window action-required deadlines plus recent Office Actions from both case-file events and prosecution documents, including ROA-filed and §2(d) indicators. Use this for questions like "what correspondent tasks should this firm focus on over the next 30 days?" or "what recent OAs does this law firm have?".

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".

Get the leading correspondents or attorneys inside one named law firm, ranked by filing volume with prosecution and TTAB activity counts. Use this when the user asks for top correspondents at a specific firm, such as "Who are the top correspondents at Fross Zelnick?"

Get the latest office action for a trademark serial number, plus the latest recorded response if one exists, and the VERIFIED refusal grounds (with cited registration numbers) parsed from the OA text. The refusal_grounds field is the authoritative, parsed basis of the refusal (rather than 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.

Get a compact TTAB history for one owner with substantive inter partes, opposition, cancellation, extension, appeal, and role breakdowns. Do not equate total records with initiated oppositions. Use get_owner_ttab_enforcement for date ranges or challenged-mark/class analysis.

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`).

Get aggregate statistics about USPTO trademark filings, registrations, and TTAB proceedings.

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.

Rank the parties that filed the most TTAB oppositions (or cancellations) across the whole Board in a date range — the market-wide "who opposes the most" question. Use this for questions like "which party filed the most oppositions in April 2026?". Do NOT substitute get_owner_ttab_stats (one owner) or get_ttab_proceeding_details (one proceeding); this is the only tool that ranks filers market-wide. Pass the exact calendar range the user implied.

Check whether a trademark is FAMOUS — and, critically, famous FOR A SPECIFIC MARKET (you pass the applicant's Nice class as a PROXY for that market; fame is market-determined, there is no per-class fame doctrine). Fame is market-specific (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/dilution-tier household name vs market-specific), the famous market footprint (expressed as Nice classes), portfolio size, and the corporate family's TTAB-as-plaintiff enforcement history. Use for "is X a famous trademark?", "is X famous for <goods>?", gauging a senior mark's §2(d) strength, or §43(c) dilution eligibility. It is a circumstantial signal, not statutory fame proof.

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.

Find trademarks whose WHOLE mark sounds similar to the given mark (Metaphone + trigram, whole-mark similarity threshold). LIMITS: it compares entire marks, so multi-word marks that merely CONTAIN a sound-alike word are invisible to it — "KWIK REWARDS" will NOT surface for a QUICK query even though KWIK sounds like QUICK. Thin or empty results are NEVER evidence that no sound-alike marks exist and NEVER support an availability/clearance conclusion: answer availability questions with run_knockout_search, the actual clearance engine.

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.

Resolve an owner, law firm, correspondent, mark, TTAB proceeding, client, or portfolio to the best trademark entity match. Resolving clients and portfolios requires authentication.
