Patent PreCheck tools (12, 1 write)

write = sends, deletes, buys or posts
  • precheck_compare_to_patentFree

    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.

  • precheck_cpc_suggestFree

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

  • precheck_deliverablesFree

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

  • precheck_legal_contextFree

    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.

  • precheck_lookup_patentFree

    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.

  • precheck_pillarsFree

    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.

  • precheck_prior_artFree

    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`.

  • precheck_rejection_patternsFree

    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.

  • precheck_scorewrite actionFree

    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`.

  • precheck_search_corpusFree

    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.

  • precheck_session_statusFree

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

  • precheck_start_reviewFree

    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.
