Why Choose Me
Drafting, automated. Judgment, mine.
The system handles drafting, terminology, and grammatical normalization. My attention stays on scope decisions, claim-spec alignment, and source-intent reconstruction — the calls that decide whether a claim survives examination.
Sharpened by 10 Million Words of Review.
7+ years in English-to-Japanese patents — 10 million+ words of review work plus 3 million+ words translated, across electrical and mechanical engineering, including medical devices. That review experience shapes every translation I deliver.
Built for How Patents Actually Break.
Terminology drift. Reference mismatches. Modifier-scope flips. My workflow catches each before I run human review.
Non-Native English? Reconstructed, Not Just Read.
Patents drafted in non-native English. I reconstruct the intended meaning behind the structural irregularities and produce clean Japanese.

Out of scope
Chemistry, pharmaceuticals, biotechnology, clinical and diagnostic inventions, and formulations (food, cosmetics, agrochemicals)
Test: the claims are defined by chemical composition, chemical structure, or biological material. A device patent that mentions a material in passing is in scope. If the field is unclear, send the document, and I will confirm before quoting.
Translation toolI work best in my own translation system, where terminology locking and consistency checks run on every project. MateCat can be used optionally, with turnaround quoted per project. Projects that require other CAT tools, such as Trados, are not accepted.
About Me
Based in Kyoto. 7+ years on patents. First in-house at a Japanese patent translation company, now freelance.
I work slowly enough to get patents right, and quickly enough to keep your filing on schedule.
I've developed my own translation system: 26,000+ lines of Python built specifically for patent work.
