Summary (for ClawHub)
A law-firm-grade CNIPA Opposition / Invalidation engine that turns case materials into examiner-readable attack briefs with IRAC, SJ-6 evidence chains, and A–E risk gates.
No templates. No fluff. No fabricated facts.
What This Skill Does
This skill ingests CNIPA registry data + case facts + evidence inventory and outputs:
- Ground selection system (main + auxiliary, prioritized)
- Element-by-element legal reasoning (Article-precise, guideline-aligned)
- SJ-6 evidence chain map (proof purpose + timeline + weak-link detection)
- Stop-loss decisions (standing / time-bar / admissibility / EV-cost kill gates)
- Submission-ready structure (Document Mode)
Constraint: No generic AI writing. No speculative conclusions. Only verifiable, evidence-backed reasoning.
v1.1 Highlights (Operational Upgrades)
- Standing & Limitation Control (Hard Gate)
- Eligibility screening before any drafting
- Time-bar traps surfaced early (relative grounds / 5-year logic where applicable)
- “不能打”的案子直接止损，不堆字
- Procedural Control Review
- Deadline control and procedural admissibility checks
- Suspension triggers / coordination with parallel proceedings
- Evidence form compliance checks (source, integrity, probative chain)
- Risk Engine Refinement (Kill Gates)
- Procedural / discretionary fatal-defect gates
- EV-cost stop-loss when expected value < cost
- Evidence weakness quantified and action-ranked
Scope & Positioning
Primary Scope
- CNIPA Opposition
- CNIPA Invalidation (absolute grounds; relative grounds where legally available)
Core Mission
Convert dispute materials into a decision-grade argument system:
- Which grounds to use (and in what order)
- Which elements must be proven
- Which evidence carries probative weight
- Which defects are fatal (stop-loss)
- How to write in a CNIPA examiner-readable structure
Not a Template Pack
This is an argument + evidence engineering engine, not a folder of sample briefs.
Legal Basis (Bounded Sources)
Operates strictly within:
- PRC Trademark Law (2019 Amendment)
- Implementing Regulations
- CNIPA Examination & Adjudication Guidelines / review norms
- Nice Classification + Similar Goods/Services Classification (use your latest internal table)
Prohibited
- Fictional statutes, fictional cases, invented timelines
- “Common sense” replacing evidence
- Fame/renown claims without third-party proof
Core Framework
1) IRAC (Mandatory, Examiner-Oriented)
- Issue: define disputes (grounds, parties, marks, timeframe, target goods/services)
- Rule: map statutes + guideline purpose + elements + burden/standard
- Application: match evidence to elements (逐要件对应，不做假设)
- Conclusion: enforceable outcome + next-step plan (补证/改路/止损)
2) SJ-6 Evidence Chain (Mandatory)
Each item is scored under:
- Authenticity
- Relevance
- Completeness
- Temporal validity
- Logical consistency
- Cross-examination resistance
Evidence organization rules
- Timeline-first
- Each exhibit must have an explicit proof purpose
- Identify the weakest link and the minimum supplementation set
3) Risk Module (A–E + Kill Gates)
Outputs include:
- Risk Level: A / B / C / D / E
- Risk Dimensions: Substantive / Evidentiary / Procedural / Discretionary / EV-cost
- Kill Gates: standing缺失、时效障碍、证据不可核验、路径不适配、成本倒挂等
Supported Scenarios
- Opposition: absolute / relative grounds (route-prioritized)
- Invalidation: absolute grounds; relative grounds within applicable time limits
- Bad-faith pattern attack: serial filings / hoarding / imitation patterns
- Cross-class confusion reasoning: confusion → similarity inference where supported
- Evidence gap diagnosis: replace low-value evidence; build high-signal chain
- Overloading control: avoid “全都写上”造成裁量反噬
Input Requirements (Minimum Viable Case Packet)
Provide at least:
- Target trademark number(s), status, filing/registration dates
- Parties and relationship clues (if any)
- Designated goods/services + class(es)
- Case timeline (publication/registration + prior use milestones)
- Intended grounds (optional; engine can propose)
- Evidence inventory: source / date / type / brief / proof purpose (if known)
If inputs are incomplete → conservative output by design.
Output Modes
Quick Mode (Fast Triage)
- rule positioning
- route shortlist (main/aux)
- key evidence checklist
- go/no-go (no full IRAC)
Pro Mode (IRAC + SJ-6 + Risk)
- full IRAC
- evidence chain diagnosis + weak-link list
- A–E risk rating + kill-gate triggers
- conservative success probability range
- action plan + supplementation list (ranked by ROI)
Document Mode (Submission-Ready)
- neutral official tone
- statute + evidence driven
- no probabilistic language
- paragraphing optimized for CNIPA examiner reading
- exhibits indexed + proof-purpose mapping + timeline tables (if provided)
Compliance & Hard Constraints
- No fabricated facts, transactions, screenshots, or dates
- No speculation without evidentiary support
- No inflated influence/fame claims without third-party proof
- Always surface: weakest link + minimum fix
- If expected value < cost → advise against proceeding + alternatives
Typical Use Cases (Law-Firm Grade)
- CNIPA opposition brief drafting (attack route selection + structure)
- CNIPA invalidation petition drafting (absolute/relative route control)
- Bad-faith chain construction (pattern proof + linkage logic)
- Evidence packet engineering (what to keep / replace / add)
- Client-facing risk memo (non-guarantee, cost-aware, decision-grade)
How to Use
- Provide registry data + facts + evidence inventory
- Choose mode: Quick / Pro / Document
- Receive:
- prioritized grounds,
- element-based reasoning,
- evidence chain + gaps,
- risk rating + next actions,
- (Document Mode) submission-ready structure.
Versioning Notes
