Tools

• precheck_compare_to_patent ~209 tokens
  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_suggest ~193 tokens
  Suggest Cooperative Patent Classification (CPC) codes for an invention description. Offline heuristic — informational only. No network call.
• precheck_deliverables ~150 tokens
  Return download URLs for finalized ICR deliverables (filing packet, coaching report, package zip, scorecard PDF). Requires report_id and session_key.
• precheck_legal_context ~172 tokens
  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_patent ~175 tokens
  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_pillars ~80 tokens
  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_art ~251 tokens
  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_patterns ~221 tokens
  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_score ~410 tokens
  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 →
• precheck_search_corpus ~239 tokens
  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_status ~144 tokens
  Return status for an active Interactive Code Review session. Requires report_id and session_key from the user access email link.
• precheck_start_review ~198 tokens
  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.
