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)
1) 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
2) Procedural Control Review
Deadline control and procedural admissibility checks
Suspension triggers / coordination with parallel proceedings
Evidence form compliance checks (source, integrity, probative chain)
3) 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.
