This is the second practical implementation guide following “Outbound-Patent Engineer Tries Patent Family Search with Generative AI”
While the previous article covered application in search operations, this one demonstrates systematic application in document creation work.
The template introduced in this article was developed through trial and error in actual practice.
Seeking to systematize Japanese-to-English patent translation review
One of the important tasks for outbound-patent engineers is Japanese-to-English translation review. Unlike search operations, review involves numerous checkpoints requiring a systematic approach.
This article introduces a systematic review method using prompt chains. You can customize this template to suit your specific practice needs.
Note: This article primarily assumes use in patent firms, though patent translation companies may also be able to use it with customization.

[Important] About This Template
This prompt chain is not a “finished product.” In actual use, while helpful, many parts don’t reach a practical level as-is.
Furthermore, this template is primarily intended to provide an experience of using prompt chains, and is not designed to fully address country-specific patent practices. For practical use, please confirm practice requirements with patent attorneys/firms in each country and customize accordingly.
However, it serves as a starting point for customization and a framework for interactive review work with AI.
🔗What Is a Prompt Chain?
A prompt chain is a system of multiple prompts (instructions to AI) linked in stages. This template divides Japanese-to-English translation review into five stages:
- Basic information confirmation
- Preliminary review (source text issues, etc.)
- Basic review (important translation quality items)
- Detailed review (individual element checks)
- Overall assessment and feedback creation
At each stage, humans verify results and provide additional instructions as needed.
📋Why Templates Are Necessary
1. Systematizing Review Items
Patent translation review involves numerous aspects:
- Technical terminology consistency
- Compliance with destination country requirements
- Semantic consistency with source text
- Appropriateness of legal expressions
A “framework” is needed to systematically verify these elements.
2. Leveraging AI’s Strengths
AI excels at:
- Term extraction and listing
- Formal consistency checking
- Terminology comparison with applicant websites
However, human verification remains essential for technical validity judgments.
3. Foundation for Customization
Each firm has:
- Different priority review items
- Client-specific requirements
- Technical field specialties
A customizable template effectively addresses these variations.
🔍Common Issues Discoverable Through This Template
This template is designed to help discover issues such as:
Terminology Inconsistencies
Mixed use of “support member” and “supporting member” for the same component can confuse readers and indicates lack of consistency.
Source Text Issues
Translation processes sometimes reveal problems in the original text, such as figure reference errors or duplicate paragraph numbers. While these cannot be corrected in translation, they can be reported as added value to clients.
Technical Validity
The template can identify technically impossible expressions (such as reversed relationships between materials and products) even when grammatically correct.
📊Prompt Chain Template Overview
20+ Item Structure
This template comprises 20+ checkpoints. Key items include:
- Section heading check – Alignment with destination country standards
- Product liability considerations (optional) – Avoiding risk-suggesting expressions
- Technical term extraction and verification – Completeness of terms with drawing reference numerals
- Applicant-specific terminology check – Alignment with company’s official terminology
- Semantic consistency between source and translation – Accuracy of subject-object relationships
- Translation completeness – Checking for omissions and mistranslations
- Technical validity – Logical process confirmation
(The template containing all items is available via the download link at the end of this article)
Step-by-Step Approach
Rather than processing all items at once, verify in stages:
[Stage 0: Basic Information Confirmation]
→ User confirmation
[Stage 1: Preliminary Review] (Items 1-2)
→ User confirmation
[Stage 2: Basic Review] (Items 3-7)
→ User confirmation
[Stage 3: Detailed Review] (Items 8-19)
→ User confirmation
[Stage 4: Overall Assessment] (Item 20)
🛠️Customization Methods
1. Removing Unnecessary Items
Example: For US filing specialists
- Remove Europe/China-specific requirement checks
- Elaborate on US-specific requirements
2. Adding Custom Items
Example: For pharmaceutical field
21. Pharmaceutical Terminology Check
"Verify that expressions related to drug dosage and administration comply with FDA guidelines. Pay particular attention to:
- Proper use of dosage/dose
- Standard expressions for administration route
- Clinical trial phase descriptions"
3. Adjusting Prompts
Modify existing prompts for your practice:
Before:
List technical terms in Japanese and their English translations in tab-delimited format.
After (Detailed version):
List technical terms in Japanese and their English translations in tab-delimited format.
Categorize them as follows:
1. Equipment/Component names
2. Process/Method names
3. Material/Substance names
4. State/Property names
Also, identify any differences from the client's preferred terminology (registered in project knowledge).
4. Super Easy AI-Powered Customization
After explaining manual customization methods, there’s actually an even simpler way.
Just give Claude this template and ask to “customize it for ___”.
Examples
"Please customize this prompt chain template for pharmaceutical field applications"
"Create a US filing-only version. Remove Europe and China items"
"We handle many electrical/electronics patents, so please optimize for that field"
That’s really all there is to it.
Actual Dialogue Example
User: "We handle many chemical patents, so please create a version emphasizing IUPAC nomenclature checks"
Claude: "Understood. I'll customize for the chemical field:
- Adding IUPAC nomenclature check as an independent item
- Emphasizing chemical formula and reaction notation
- Specializing Item 16 for chemistry
[Generates customized template]"
No need for manual customization. Through AI dialogue, your practice-optimized prompt chain is completed in minutes.
5. Creating from Scratch (Also Simple)
“But how do you create a prompt chain template in the first place?” you might wonder.
Actually, no special knowledge is required. I created mine from scratch using this method:
Step-by-Step Creation Process
- Conduct translation review in regular chat
- Perform actual translation review work through dialogue with Claude
- Proceed while confirming step by step
- Convert procedures to template
"Please create a prompt chain template from the translation review procedures we performed in this chat that can be used for other projects" - Save the template
- Save the generated markdown template locally
- Try on next project
- Register saved template in project knowledge (recommended)
- Or paste at the beginning of a new chat
- Use for actual translation review
- After review completion, ask AI to extract improvement points
"Looking back at this translation review, please list the points that need improvement in the prompt chain template"
- Improve while using
"Please update the prompt chain template in project knowledge to reflect the improvements needed from this review"💡 Practical Tip
It’s recommended to perform translation review work and template improvement in separate chats. Doing both in the same chat can quickly hit character limits and cause confusion by mixing different purposes. - Refine through repetition
- Naturally optimized by repeating steps 3-5
In short, just cycle through “Actual work → Template creation → Improvement”.
No special prompt engineering knowledge needed. You can directly convert your daily practice into templates.

🔧Integration with Other Tools
Effective Integration with Iro de Check
This template can be effectively integrated with “Iro de Check,” widely used in the patent translation industry.
Integration Points:
- The technical term list (tab-delimited format) extracted in Item 3 of the template can be directly used as a custom glossary for Iro de Check
- Combining AI’s contextual checking with Iro de Check’s comprehensive terminology consistency verification enables more reliable quality management
Practical example: At our firm, we import AI-generated tab-delimited term translation lists into Iro de Check to verify terminology consistency.
⚠️Practical Considerations
Appropriate Management of Confidential Information
When using AI tools, please note:
- For content containing unpublished technical information or trade secrets, review each AI service’s terms of use and data handling policies
- For particularly sensitive information such as pre-filing invention content, make decisions at your own discretion
Human Judgment Is Final
- Use AI suggestions as support tools only, with final decisions always made by humans with professional expertise
- Confirmation by specialists in the relevant field and jurisdiction is essential for technical validity and legal judgments
When Source Text Issues Are Found
Translation review processes may reveal source text issues (figure reference errors, duplicate paragraph numbers, etc.). While these cannot be corrected in translation, reporting them as “source text issues” provides added value.
📚Real-World Template Applications
Case 1: Improving Terminology Consistency
One user improved the Item 3 (technical term extraction) prompt:
Improved version:
"Extract technical terms and present in the following format:
Japanese | Translation 1 | Translation 2 (if any) | Recommended | Reason
When multiple translations exist for the same term,
indicate recommendations based on technical field conventions."
This enabled efficient discovery and correction of terminology inconsistencies.
Case 2: Applicant-Specific Checks
For firms with many cases from specific clients:
Additional item:
"For the following key terms used in [Client Name]'s US patents
over the past 5 years, verify usage in this translation:
- control unit → Translation of 制御部
- processing module → Translation of 処理モジュール
[Additional client-specific key term list]"

🚀Future Developments: Application to Office Action Responses
We are currently exploring ways to apply this prompt chain template approach to foreign patent prosecution (office action responses).
Anticipated Challenges and Solutions
While there are challenges in applying this to prosecution work, we believe they are solvable:
1. Complexity of Review Items
- Review items varying by rejection types in each country
- Different response strategies for each applicant
→ Solution: Gradually improve completeness by repeatedly applying the methods described in this article
2. Volume of Documents to Process
- Office actions, cited references, application specifications
- Prosecution history, amendment records
- Status of corresponding foreign applications
→ Challenge: AI has limitations on the amount of documents it can process at once and cannot handle all documents simultaneously
→ Solution: Divide processing across multiple chats within a project (modularization of prompt chains is also under consideration)
The “Practice → Template → Improvement” cycle developed for translation review shows potential for application to other patent practices.
🔬Reference: A Practical Approach Based on Understanding AI Limitations
Structural Limitations of AI Discovered Through Actual Use
Using this template in practice revealed that AI has the following structural limitations. These are constraints of current AI technology, and understanding them properly enables more effective utilization.
1. Narrow Interpretation of Limited Instructions
Core Issue: When AI receives limiting instructions like “major” or “representative,” it judges that requirements are met with minimal verification. While humans would think “let’s check broadly just to be sure,” AI lacks this judgment.
2. Inability to Say “I Don’t Know”
Core Issue: Even when uncertain, AI generates responses based on speculation. After giving definitive answers, it may turn out that AI didn’t understand from the beginning.
3. Positive Reporting Bias
Core Issue: When the overall impression is favorable, AI tends to conclude “generally correct” and neglects searching for localized serious errors. It tends to give answers that would please the operator.
4. Baseless Weighting and Prioritization
Core Issue: AI may arbitrarily judge what is “important,” “main,” or “priority.” When asked “what else besides the main items,” it cannot answer, and when asked for the basis of prioritization, it becomes vague.
5. Inability to Judge Appropriate Detail Level (Granularity)
Core Issue: AI doesn’t understand the human concept of “just right.” When asked to be concise, it removes important information; when asked to be detailed, it includes unnecessary information. It tends toward 0 or 100 extremes.
6. Unawareness of Document Structure
Core Issue: Information often concentrates in specific sections of patent specifications, but unless explicitly instructed, AI doesn’t consider structural characteristics of documents and samples evenly from the entire text.
7. Superficial Understanding of Technical Context
Core Issue: AI doesn’t automatically connect abstract technical understanding with concrete verification. Even when understanding the overall mechanism, it may miss individual technical errors.
8. Pattern Recognition Failure
Core Issue: AI processes individual incidents independently and doesn’t extract common patterns from multiple incidents unless explicitly instructed. It may not recognize systematic problems even when they exist.
9. Perfunctory Completion of Checklist Items
Core Issue: AI tends to prioritize formally completing given task lists while neglecting substantial quality assurance.
Feasibility Study Results
We examined two approaches to these problems:
Option 1: Comprehensive Checking by AI
- Technically possible but processing becomes enormous for specifications exceeding 100 paragraphs
- Due to AI’s context limitations, information from early paragraphs may be lost in later paragraphs
- Conclusion: Currently impractical
Option 2: Role Division Based on AI Limitations
- Mechanical verification tasks handled by specialized tools (like Iro de Check)
- AI specializes in technical coherence verification requiring contextual understanding
- Conclusion: This is the only practical solution
Recommended Practical Approach
Specializing in AI’s Strengths
- Technical coherence judgments considering context
- Complex sentence structure analysis
- Terminology comparison with applicant websites
- Verification against technical field conventions
Tasks Best Left to Specialized Tools
- Comprehensive verification of large data sets
- Mechanical matching/mismatching checks
- Consistency maintenance across long documents
- Complete checking of all reference numerals and terms for omissions
Summary
Rather than seeking perfection, it’s important to leverage each tool’s strengths. By understanding AI’s limitations and appropriately combining it with specialized tools like Iro de Check, practical quality management can be achieved.
