/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]"
• "freedom to operate analysis"
• "FTO for [product]"
• "patent landscape for [field]"
• "is [invention] novel"
• "patents on [topic]"
• "competitive patent analysis"
• "prior art for litigation"
• "patent diligence on [company]"

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
