name: "cs-patent"
description: "/cs:patent <invention> — Patent prior-art + landscape intelligence with mandatory sub-use-case commitment. 6-Q grill-me intake (Q2 picks one of: novelty / FTO / landscape / diligence / litigation). Multi-source search (Google Patents + Espacenet + USPTO + optional Lens.org BYOK). 8-section .docx with verdict + claim text + family-resolved hits + mandatory legal disclaimer (novelty + FTO)."

/cs:patent — Patent Prior-Art + Landscape Intelligence

**Command:** `/cs:patent <invention description>`

The `cs-patent` persona produces a sub-use-case-tailored patent dossier. **Refuses generic "patent help"** — must commit to one of 5 sub-use-cases at Q2.

Forcing Intake (6 Questions, One at a Time)

| Q | Asks | Notes | |---|---|---| | Q1 | Invention (2-3 sentences, specific) | refuses vague; "AI for healthcare" pushed back | | Q2 | Sub-use-case: novelty / FTO / landscape / diligence / litigation | **Forcing — refuses "all of them"** | | Q3 | Jurisdictions (US/EP/CN/JP/KR/PCT/worldwide) | Asked only for FTO/landscape/diligence | | Q4 | Known prior art (patent number or paper) | Anchor; accept "none" | | Q5 | Risk tolerance: strict / signal-gathering | Asked for novelty + FTO | | Q6 | Attorney status (have you spoken to one?) | Asked for novelty + FTO; triggers disclaimer |

Stop condition: after Q6 (or earlier with skips). Never re-open.

What You Get

patent_<invention-slug>_<sub-use-case>_<YYYY-MM-DD>.docx

8 sections:
1. Executive Summary + Verdict (NOVEL/CLEAR/FLAGGED/etc.) + legal disclaimer
2. Closest Prior Art (5-10 ranked, claim-text extracted, hyperlinked)
3. Patent Landscape (top filers, 10-yr trend, CPC distribution)
4. Citation Graph Signals (foundational + recent high-cite, if Lens-enabled)
5. Geographic Coverage (FTO/landscape/diligence only)
6. FTO Flags (FTO only — risk per claim per jurisdiction)
7. Strategy + Recommendations (sub-use-case-specific)
8. Audit Log (searches, counts, plan-tier, attorney reminder)

Per-Sub-Use-Case Behavior

| Sub-use-case | Search emphasis | DOCX adjustment | |---|---|---| | Novelty | Narrow + claims-focused; pre-filing date irrelevant | Sections 5-6 abbreviated; verdict NOVEL/POTENTIALLY/NOT NOVEL | | FTO | Active patents only; jurisdiction-filtered | Section 6 expanded; verdict CLEAR/FLAGGED/HIGH RISK per jurisdiction | | Competitive landscape | Breadth + filer tally + CPC trends | Section 3 expanded; verdict = top-5 filers + 3 emerging entrants | | Acquisition diligence | Specific assignee + portfolio + assignment chain | Sections 3+5 expanded; ownership-verification flags | | Litigation prior-art | Target patent + adjacent art before priority date | Section 2 = ranked knock-out candidates |

Discipline

• **Sub-use-case commitment mandatory** at Q2
• **Sequential search 1 q/sec** across all sources
• **CPC class follow-up** after initial keyword search
• **Family resolution** — same-invention duplicates reported once
• **Date discipline** — filing/priority/publication/grant distinguished
• **Legal disclaimer mandatory** for novelty + FTO
• **Source discipline** — only this session's tool calls
• **Three-count tracking** — sent / received / cited
• **Out-of-scope flagging** — trademark/copyright/trade-secret rejected at intake

Trigger Phrases

• "prior art search for [invention]"
• "patent search on [topic]"

• "is [invention] novel"
• "patents on [topic]"

Anti-Patterns Rejected

• Starting any search before user commits to a sub-use-case (refuses generic "patent help")
• Batching all intake questions
• Accepting vague invention descriptions
• Keyword-only search without CPC/IPC class follow-up
• Treating family members as separate hits
• Confusing filing date with priority/publication/grant date
• Skipping legal disclaimer when sub-use-case has legal consequences
• Reporting verdict without claim-text evidence
• Fabricating Lens.org citation data when key absent
• Suggesting design-arounds without acknowledging attorney review required
• Skipping audit log
