The firm
A Japanese patent and trademark firm at CO-LABO SAKURA in Yukarigaoka, Sakura, east of Tokyo. About 5,000 clients to date, a substantial share of them filing into Japan from abroad.
The attorney who answers your first email is the attorney who files the case and who argues it if the examiner objects. Nothing is handed to an account manager, and the file does not move between people. For trademark work, the whole matter — first question, filing, examination, registration — runs by email.
We publish our fees rather than quoting on request, and we do not mark up Japan Patent Office official fees. Where we think an application is unlikely to succeed, we say so before taking the instruction, not after the refusal arrives.
Nobuhide Koiwa — Registered Patent Attorney (benrishi), Registration No. 100167715. Main areas: trademarks and designs.
Email reaches us fastest, and it reaches the attorney directly. Japan is UTC+9; we answer on business days between 9:00 and 18:00 Japan time.
