Conduct FTO patent searches and infringement risk analyses by querying granted and pending patents based on technical descriptions and images.

FTO Patent Infringement Risk Search and Analysis Skill

Overview

This skill is used to execute complete FTO (Freedom-to-Operate) patent search and infringement risk analysis, helping users identify potential patent infringement risks before product launch or technology implementation.

Supported Search Platforms:

• Google Patents (Free): https://patents.google.com - No login required, publicly accessible
• Patsnap (Account Required): https://analytics.zhihuiya.com - Commercial patent database, user login required

Execution Process (9 Steps)

Step 1: Collect User Input

Required:

• Technical solution description (text + optional images)
• Search jurisdictions (e.g., CN / US / EP / WO / JP / KR, multiple selection allowed)

Optional Configuration:

• Exclude design patents (Default: Exclude design, search invention/utility model only)
• Target applicant whitelist / blacklist
• Search time range
• Search platform selection (Google Patents / Patsnap, default: Google Patents)

Default Rule: FTO search only focuses on granted patents (GRANT) and pending patents (PENDING). Expired patents do not pose infringement risk and are automatically excluded.

If user provides images:

1. Use image analysis capability to identify technical structures in the image
2. Refine/supplement technical solution description based on image content
3. Integrate structural features from the image into text description

Output Confirmation Template:

text

Input received. Search configuration as follows:
- Technical Solution: [Summary]
- Jurisdictions: [List]
- Patent Status: Granted (GRANT) + Pending (PENDING) only, expired patents excluded
- Patent Type: [Invention + Utility Model, design excluded]
- Key Applicants: [List or None]
- Search Platform: [Google Patents / Patsnap]

Please confirm the above configuration, or advise any adjustments needed.

---

Step 2: Technical Solution Analysis and Technical Point Decomposition

If user provides images, first refine technical solution description based on images:

• Identify structural features in the image (shape, connection relationships, positional relationships)
• Supplement details that may be missing from text description
• Merge image recognition results with text description to form complete technical solution

Then decompose the technical solution into independent technical points (each technical point is a separately searchable technical module).

No.	Technical Point Name	Brief Description	Risk Rating
TP-1	[Core Structure Module]	[Description]	🔴 High Risk
TP-2	[Control Method Module]	[Description]	🟡 Medium Risk
TP-3	[Auxiliary Function Module]	[Description]	🟢 Low Risk

Risk Rating Criteria: 🔴 Core function / patent-intensive 🟡 Important function / some coverage 🟢 Common technology / expired

Confirm technical point decomposition results with user. User may add, delete, or modify.

---

Step 3: Technical Feature Extraction for Target Technical Point

Select the highest risk technical point for technical feature extraction.

Feature No.	Technical Feature Content	Function/Effect	Feature Level
F-1	[Specific technical feature description]	[Function/Effect]	Technical Field Feature
F-2	...	...	Core Essential Feature

Feature Level: Technical Field Feature → Core Essential Feature → Basic Essential Feature → Additional Feature

---

Step 4: Build Search Element Table

Search Element Table:

Element Category	Core Keywords (OR Expansion)	Proximity Operators	IPC/CPC Classification
Subject Name	fan; ceiling; light; lamp; fixture	"ceiling fan"~2	F04D25/088; F21V33/00
Function/Object	fold; retract; stow; deploy; pivot	"fold stow"~2	F04D29/362
Technical Element-Structure	blade; arc; arcuate; overlap; scimitar	"arc blade"~2	F04D29/384; F04D29/36
Technical Element-Relationship	radius; above; position; axis; vertical	"pivot axis"~2	F04D29/34

Keyword Design Principles:

• Prioritize single core words (blade / pivot / fold / stow)
• Use OR for synonyms; use AND between different elements
• CPC classification codes are more precise than IPC (use subclass level)

---

Step 5: Develop Search Strategy and Iteration

Develop multi-dimensional search strategies to ensure comprehensive coverage of risk patents.

Status Filter (Must be appended to all search queries):

• Google Patents: (status:GRANT OR status:PENDING)
• Patsnap: Legal Status:(Granted OR Pending)

---

S1: Subject Name + Function (Broad Starting Point)

text

S1:
(fan OR ceiling) AND blade AND (fold OR retract OR stow)
AND (status:GRANT OR status:PENDING)
→ Estimated hits: ~300 (raw), ~150 (after status filter)

S2: Subject Name + Main Technical Elements

text

S2:
(fan OR ceiling) AND blade AND (pivot OR hinge) AND (arc OR arcuate OR curved)
AND (status:GRANT OR status:PENDING)
→ Estimated hits: ~120 (raw), ~60 (after status filter)

S3: Precise Classification + Technical Elements

text

S3:
CPC:F04D29/36 AND blade AND (fold OR retract OR stow)
AND (status:GRANT OR status:PENDING)
→ Estimated hits: ~80 (raw), ~45 (after status filter)

S4: Semantic Search (Google Patents Semantic Search)

text

Enter 2-3 sentences of core technical description in Google Patents semantic box:

Example input:
"ceiling fan blades pivot about vertical axis between stowed position 
above light fitting and deployed position, arcuate blades overlap 
neighbors when stowed within radius of circular light enclosure"

→ Add filter to page results: status:GRANT OR status:PENDING
→ Estimated semantic hits: ~40~80 (about half after status filter)

S5: Citation Tracking

text

Forward Citation Tracking:
  Visit core patent page → View "Cited By" list
  → Add filter: status:GRANT OR status:PENDING

Patent Family Tracking:
  Visit core patent page → View "Patent Family" list
  → Confirm if there are valid family members in target jurisdictions (US/CN/EP)

Search Results Summary Table:

Search No.	Query (Abbreviated)	Database	Raw Hits	After Filter
S1	(fan OR ceiling) AND blade AND (fold OR stow)	GP	~300	~150
S1-1	("ceiling fan"~2) AND blade AND (fold OR stow) AND light	GP	~80	~45

---

Step 6: Execute Search and Recommend Relevant Patent List

Use browser_use to execute searches, record hit counts for each strategy (raw + after status filter).

Recommended Patent List Format (20 patents) - Must Include Legal Status Column:

No.	Patent No.	Title	Assignee	Pub Date	Legal Status	Expected Expiry	Simple Family	Main IPC	Relevance
1	USXXXXXXB2	[Title]	[Assignee]	[Date]	✅ Granted	[YYYY-MM]	CN/EP	F04D25/088	⭐⭐⭐

Legal Status Description:

• ✅ Granted (GRANT): Authorized and maintenance fees current, poses substantial infringement risk
• 🔄 Pending (PENDING): Not yet granted, will pose risk upon grant (monitor claim evolution)
• ⚠️ Partially Invalidated: Some claims invalidated via IPR/invalidation proceedings

Sorting Criteria:

1. Claim similarity (highest priority)
2. Technical problem similarity
3. Technical field similarity
4. Legal status (Granted > Pending)

---

Step 7: High-Relevance Patent Technical Feature Comparison

Select the 3 most relevant patents for feature-by-feature comparison according to the All Elements Rule.

Feature	Claim (Patent X)	Target Technical Solution	Literal Comparison	Doctrine of Equivalents
1	[Feature description]	[Corresponding description]	Y/N	Y/N/—

All Elements Rule:

• All essential technical features of the claim must be covered by the target product to constitute infringement
• Y = Literal coverage; N = No coverage
• Doctrine of Equivalents: Different in wording but same function, same means, same effect

Conclusion Format:

text

Analysis: [Technical feature recorded in claim X]. The target product has the same feature.
Conclusion: Claim [No.] of patent [No.] covers/does not cover this target product.

Key Considerations

1. All Elements Rule: Infringement analysis must compare all essential technical features of claims one by one
2. Analyze Granted/Pending Patents Only: Expired patents are excluded from FTO analysis scope
3. Legal Status Required: Patent list must indicate ✅Granted / 🔄Pending
4. Latest Publication: Prioritize B2 > B1 > A versions
5. Doctrine of Equivalents: Different wording does not mean no infringement; equivalence must be analyzed
6. Confidentiality Reminder: FTO reports are confidential documents; mark confidentiality level
7. Image Processing: If images are input, must first perform image recognition and refine technical solution
8. Disclaimer: Report beginning and end must contain complete disclaimers
