Thank you for visiting our website.
M&Partners IP, P.C. is a Japanese IP firm founded in Kyoto in 2002. We provide practical support for foreign associates and overseas clients seeking reliable representation in Japan.
Our work includes patent filings in Japan via the PCT national phase and the Paris route, utility model filings, trademark filings and responses to provisional refusals under the Madrid Protocol, Design applications via the Hague System, as well as searches, opinions, and dispute-related support.
We regularly work with foreign law firms and IP firms as Japanese associate counsel. We place great importance on clear communication in English, practical advice, and responsiveness in cross-border matters. We are also available for online meetings and often meet foreign associates and clients in person at international IP conferences (INTA/APAA/FICPI/AIPPI/AIPLA/LES etc) and other professional events.
Our managing partner also served as a court-appointed technical advisor in intellectual property litigation in Japan for 14 years, from 2008 to 2022. We believe this experience has given us practical insight into technically complex IP disputes in Japan.
We look forward to working with foreign associates and overseas clients who need dependable support for Japanese IP matters.
