GleanMark

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

compare_marks

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.

get_correspondent_specialization

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.

count_filings_by_period

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.

count_trademarks_by_attributes

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.

get_deadline_satisfaction_mapping

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_mark_deadlines

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_owner_deadlines

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.

get_fame_profile

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.

fetch

Finds third-party coexistence evidence for a Section 2(d) likelihood-of-confusion refusal: pairs of live registrations owned by different parties that coexist on the federal register, one covering goods like the applicant's and one covering goods like the cited registration's. Takes the cited registration number plus the applicant's goods, given either as a filed application's serial number or, for an unfiled mark, as a free-text goods description with its Nice classes. Returns the coexisting pairs (marks, serial and registration numbers, owners, classes) and whether the number of pairs reaches the level usually treated as supportive; pairs are returned even when the count is below that level. Reads the public register only. Requires a signed-in GleanMark account.

get_coexistence_evidence

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_similar_marks

Search for visually or conceptually similar U.S. design and combined marks, optionally limited by USPTO claimed-color metadata. An image URL, uploaded-image URL, or existing serial/registration number uses true image-to-image similarity. A plain-English description and/or USPTO design codes uses semantic design similarity with exact-code boosting. Color limits candidate eligibility; visual/conceptual similarity still determines ranking. Returns mark images, color claims, and similarity signals.

search_design_similarity

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_firm_correspondent_tasks

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.

get_firm_deadlines

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_firm_oa_outcomes

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.

get_chain_of_title

Citation history of one cited mark: every Office Action in GleanMark's parsed corpus that cited this registration (or pending application) against other applicants under Section 2(d), grouped by refused application, with what happened to each application (registered later, abandoned or still pending), the recorded outcome where a later action states one (withdrawn, obviated or maintained), and whether response text is on file. Answers questions such as how often a registration has been cited and whether applicants overcame the citation. Takes a registration number or a serial number; a mark name needs to be resolved to one of these first. Counts cover GleanMark-parsed Office Actions only, not every USPTO action. What was cited against a user's own application is returned by get_oa_case_detail and get_latest_office_action.

get_cited_mark_history

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

get_class_relationships

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.

get_ttab_top_opposition_filers

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_prosecution_document

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_ttab_document

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.

get_mark_international_profile

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_latest_office_action

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).

get_owner_related_parties

List famous brand families, optionally filtered by Nice class, fame path, or broad (dilution-tier) only, ranked by portfolio size. Capped at 50 results with no pagination. Use for "famous marks in Class 25", building a leaderboard, or surveying the crowded-field around a term. Circumstantial signal, not statutory fame proof.

list_famous_marks

Lists every live USPTO mark containing a term as a whole word, including marks that match only through their USPTO pseudo-mark (respellings and compounds: for QUICK, marks such as KWIK REWARDS, QUICKSHIP and B-KWIK). Optional Nice class filter. Paged with limit (default 50, up to 200) and offset. Returns the full list, where get_crowded_field_evidence returns counts and about ten examples. Not a clearance search. Reads the public register only. Requires a signed-in GleanMark account.

list_marks_containing_term

List clients accessible to the authenticated user. Respects firm-wide or restricted access modes.

get_my_clients

List trademark owners you are currently tracking, enriched with portfolio stats, TTAB stats, entity info, and health score. Supports ranking via limit + sort_by. For 'top pending pipeline' questions, use sort_by='pending_marks', sort_direction='desc', limit=10.

get_my_tracked_owners

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.

list_prosecution_documents

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

get_nice_classes

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.

lookup_trademark

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.

get_correspondent_marks

List trademarks in a portfolio with full details (mark name, owner, status, filing/registration dates, Nice classes, mark type, attorney) plus facets (live/dead counts, status breakdown, mark type breakdown, class distribution). Accepts a portfolio UUID or portfolio name and verifies workspace access.

get_portfolio_marks

Measures how live registrations containing a term in one Nice class treat it, for a disclaimer requirement or a Section 2(e)(1) descriptiveness refusal: how many disclaim the term and how many registered without disclaiming it, with examples of each. Reads the public register only. Requires a signed-in GleanMark account.

get_disclaimer_evidence

Measures whether a term sits in a crowded field: how many different owners hold live marks containing the term in the given Nice classes, with registered examples that can be cited. Relevant when arguing that a shared term is weak and entitled to a narrow scope of protection. Returns the distinct-owner count, isCrowded (true only when the count meets the standard threshold), and example registrations; isCrowded false means the register does not support a crowded-field argument for that term. Reads the public register only. Requires a signed-in GleanMark account.

get_crowded_field_evidence

Get the detailed office action case bundle for one serial number or OA document, including round context, refusal metadata, cited marks, and argument-analysis context.

get_oa_case_detail

Check whether previously launched Office Action research for a serial number is still running, expired, or complete, and fetch the completed cached result when available.

get_office_action_research_status

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_owner_filing_trends

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.

get_owner_goods_keywords

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.
