Measured tools (12)

• precheck_score

  Run a prior-art density / risk-profile pre-check on source code or an invention description. Returns a 0–100 directional score across the four USPTO statutory pillars (§101 eligibility, §102 novelty, §103 non-obviousness, §101 utility), a separate §112 filing-readiness signal, the band (Not Ready → File Ready), the pillar that holds the band back, opportunities to thicken the technical description, and a count of prior-art matches consulted. Show filename + size and get user yes, then pass confirm_upload: true. Pass the text inline via `code`.

  Parameters:

  • code (required) — string — The source code or invention description to analyze (>= 10 chars).
  • confirm_upload (required) — boolean — Required true after the user confirms filename + size. Nothing is uploaded without it.
  • tier — string — Analysis tier. Defaults to free; paid tiers require server-side entitlement.
  • filename — string — Optional filename hint (e.g. main.ts) used for language/context.
  • invention_kind — string — Optional invention category. Sets language and scoring prompts. Prior-art math still follows the disclosure.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• precheck_prior_art

  Return the closest prior-art matches consulted for an invention (titles, sources, similarity scores, URLs). Runs the same analyze pipeline as precheck_score but focuses on retrieval results. Pass invention text via `code`.

  Parameters:

  • code (required) — string — Source code or invention description (>= 10 chars).
  • confirm_upload (required) — boolean — Required true after the user confirms filename + size.
  • tier — string — Analysis tier. Defaults to free.
  • limit — integer — Max matches to return (1–15, default 8).
  • filename — string — Optional filename hint.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• precheck_rejection_patterns

  Preview examination-risk signals: similar office-action rejections, abandonment patterns, and the primary statutory basis an examiner might cite (§101/§102/§103). Use after precheck_score to explain prosecution risk.

  Parameters:

  • code (required) — string — Source code or invention description (>= 10 chars).
  • confirm_upload (required) — boolean — Required true after the user confirms filename + size.
  • tier — string — Analysis tier. Defaults to free.
  • filename — string — Optional filename hint.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• precheck_legal_context

  Return a short snippet of current US software-patent legal guidance (CAFC, USPTO, Alice/§101) relevant to scoring this invention. Informational only — not legal advice.

  Parameters:

  • code (required) — string — Source code or invention description (>= 10 chars).
  • confirm_upload (required) — boolean — Required true after the user confirms filename + size.
  • filename — string — Optional filename hint.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• precheck_pillars

  List the five scoring pillars (with statutes and weights) and the band rules used by precheck_score. Use this to explain a score to the user. No network call.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• precheck_start_review

  Return the URL where the user can start a paid (or promo-unlocked) Interactive Code Review that strengthens each pillar with evidence and produces a filing package. Use after precheck_score when the user wants to act on the result.

  Parameters:

  • email — string — Optional email hint (prefill only; user confirms on signup).
  • promo — string — Optional access code the user already has. Do not invent or guess a code.
  • report_id — string — Optional free-score report id (PPC-YYYY-MM-DD-XXXXX) to carry forward.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• precheck_search_corpus

  Fast semantic search against the 2,200,000+ prior-art corpus without LLM scoring. Returns ranked matches with similarity scores. Cheaper than precheck_score when you only need references.

  Parameters:

  • code (required) — string — Source code or invention description (>= 10 chars).
  • confirm_upload (required) — boolean — Required true after the user confirms filename + size.
  • tier — string — Search tier. Defaults to free.
  • limit — integer — Max matches (1–20, default 12).
  • filename — string — Optional filename hint.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• precheck_cpc_suggest

  Suggest Cooperative Patent Classification (CPC) codes for an invention description. Offline heuristic — informational only. No network call.

  Parameters:

  • code (required) — string — Source code or invention description (>= 10 chars).
  • limit — integer — Max suggestions (1–10, default 5).
  • invention_kind — string — Optional invention category. Physical/process uses article and method CPC classes, not G06F.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• precheck_session_status

  Return status for an active Interactive Code Review session. Requires report_id and session_key from the user access email link.

  Parameters:

  • report_id (required) — string — Report id (PPC-YYYY-MM-DD-XXXXX).
  • session_key (required) — string — Session secret from the access email (header / stored key, not a query string).

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• precheck_deliverables

  Return download URLs for finalized ICR deliverables (filing packet, coaching report, package zip, scorecard PDF). Requires report_id and session_key.

  Parameters:

  • report_id (required) — string — Report id (PPC-YYYY-MM-DD-XXXXX).
  • session_key (required) — string — Session secret from the access email (header / stored key, not a query string).

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• precheck_lookup_patent

  Resolve a US patent or application number (e.g. US1234567B2) via USPTO Open Data Portal and optionally join the indexed prior-art corpus. Returns title, status, CPC, grant-text excerpt, and a public URL. No API key required in the MCP client.

  Parameters:

  • patent_id (required) — string — US patent id (US1234567B2) or application number.
  • include_grant_text — boolean — Fetch abstract / claim 1 excerpt when available (default true).

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• precheck_compare_to_patent

  Compare invention text to a known US patent: embedding similarity plus prior-art risk analysis (statute hints, overlap theme, distinction checklist). Use when the user names a specific reference patent.

  Parameters:

  • code (required) — string — Source code or invention description (>= 10 chars).
  • patent_id (required) — string — US patent id (e.g. US1234567B2).
  • confirm_upload (required) — boolean — Required true after the user confirms filename + size.
  • filename — string — Optional filename hint.
