Quality Control & Education

In-house expertise, multi-layered checks, and close communication.
We ensure translation quality across three key pillars.

Patent translation quality should not rely solely on the skills of individual translators. We maintain consistently high translation quality by combining three frameworks: dedicated in-house translation staff, multi-layered quality assurance using proprietary tools and specialist checkers, and close communication with clients.

1Commitment of In-House Translation Staff

Our full-time professional translation staff belong to Translation Group and Translation IT Group, providing meticulous services tailored to client requirements.
Specifically, we gather initial feedback at the start of client engagements to establish customized guidelines and compile project-specific glossaries as needed.

2Translation Quality Control System:
QC Group Initiatives

Multi-Layered Quality Check System

Comprehensive Inspection via
Proprietary Tools

Every project is checked against the source text using our in-house automated system.
This mechanically prevents human errors such as omissions, numerical discrepancies, and basic grammatical errors.

Substantive Sampling Reviews by
Patent Expert Checkers

Projects selected based on specific criteria undergo in-depth review by experienced patent translation checkers, focusing on claims and key sections.
This sampling process double-functions as a translator evaluation; we enforce strict standards and suspend work assignments for translators who fail to meet quality criteria.

Peer Check (Mutual Review)

We employ a peer-review mechanism where translators review each other's work.
This serves as a continuous learning opportunity to study phrasing and logical structures, elevating overall organizational capabilities.

Quality Standardization

Standardization via Patent Specification Translation Guidelines

In addition to client-specific rules, we maintain standard translation guidelines that consolidate key patent considerations and apply them in staff training.

Example: Instead of using "means" for functional expressions, alternative nouns such as "unit" or "device" are used. Noun phrases formed with "-er" or "-or" suffixes (e.g., "detector", "analyzer") are also utilized. (Note: This rule is not applied universally if "means" is determined to be more appropriate for a specific invention.)

MPEP Reference Support System

The Manual of Patent Examining Procedure (MPEP), an essential guide for US patent practice, is positioned as a primary reference tool. We have built an AI-powered internal search system to allow translators to instantly retrieve necessary information from the extensive MPEP, ensuring accurate and up-to-date decisions.

3Emphasis on Communication

We believe that close collaboration between clients and translation staff is essential for delivering optimal translation results, and we actively promote the following initiatives:

Translator Name Disclosure and Direct Communication

While translator anonymity is common in the translation industry, we disclose our translators' names to enable direct communication with clients. For complex technical matters, translators conduct direct discussions through in-person meetings, online conferences, or technical briefings. Delivering work under their own names instills a strong sense of pride, ownership, and responsibility as representatives of Chizai Corporation.

Information Sharing via Translation Memos

For patent application specifications, we generally submit a "Translation Memo" detailing points considered during the translation process. This document clarifies the rationale behind term selections and interpretations of ambiguous source text. (If prior clarification is preferred for ambiguous passages, formal query sheets are submitted before finalizing translation.)
