Ttab

@pipeworx/ttab

Trademark disputes before the USPTO Trademark Trial and Appeal Board — oppositions, cancellation petitions, extensions of time to oppose, and ex parte appeals, with both parties, the marks at issue, and the full docket.

Part of Pipeworx — an MCP gateway connecting AI agents to 1684+ live data sources.

Tools

• ttab_search(party?, other_party?, mark?, correspondent?, serial_or_registration_number?, query?, status?, match_mode?, page?, limit?) — finds proceedings by party name, mark text, correspondent firm, or application/registration number. Each result carries the board proceeding number, proceeding type, filing date, and both sides with their marks and serial/registration numbers. Answers "is anyone opposing this trademark".
• ttab_proceeding(proceeding_number, type?) — one proceeding in full: status and status date, interlocutory attorney and paralegal, each party's correspondence address and pleaded marks, and the complete prosecution history (every docket entry, its date, and any due date).
• ttab_party_history(party, status?, match_mode?, max_pages?, limit?) — profiles a company across TTAB: how often it appears as plaintiff (opposing) versus defendant (opposed), a breakdown by proceeding type, and every name spelling it has been filed under.

Data sources

• https://ttabvue.uspto.gov/ttabvue/ — TTABVUE, the Board's inquiry system (v2.8.0). Server-rendered HTML; there is no JSON API and no bot wall.
• v?qt=adv&... is the advanced-search endpoint. Parameters: procstatus (Pending/Terminated/All), pno (proceeding number), propno (application/registration number), qs (all words anywhere), propname + propnameop (mark), pn + pop (party), pn2 + pop2 (other party), cn + cop (correspondent), page (1-based, 25 rows per page). The *op operators take '' (contains all words), beg (starts with), or mat (is exactly).
• v?pno=<number>[&pty=<type>] is the proceeding detail page.

Things worth knowing before you touch this

• An unknown proceeding number returns HTTP 200 with an empty record page, not a 404. The pack detects the blank Number: field and returns {found:false, reason:'proceeding_not_found'}; do not trust the status code.
• Result totals saturate at the literal string "100+" — result_count is a string, not a number, and the pack says so in result_count_note.
• EXT (extension of time to oppose) and EXA (ex parte appeal) are keyed by application serial number, not by an 8-digit board number, so one number can name two different records. pty disambiguates; omitting it lets TTABVUE choose, and asking for the wrong pty yields the empty page above.
• Party names are stored exactly as filed, so one company appears under several spellings. Names are returned raw, and ttab_party_history reports the spellings it saw rather than merging them.
• A proceeding has marks on both sides — the defendant's applications under attack and the plaintiff's pleaded registrations. They are kept in separate party objects, never merged into one mark list.
• Search results are three top-level <td class="p1"> cells per row (proceeding / defendant / plaintiff); nested layout tables use bare <td>, which is what makes the cell split safe.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "ttab": {
      "url": "https://gateway.pipeworx.io/ttab/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/ttab/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1684+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

curl -X POST https://gateway.pipeworx.io/v1/tools/ttab_search \
  -H 'Content-Type: application/json' \
  -d '{"party":"Nike, Inc.","limit":5}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/ttab_search. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Standalone (no gateway account)

This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:

{
  "mcpServers": {
    "ttab": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-ttab"]
    }
  }
}

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-ttab

It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call for only this pack's tools — none of the shared meta-tools the gateway connection above adds. Same source, same tools, no ask_pipeworx routing.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Ttab data" })

The gateway picks the right tool and fills the arguments automatically.
