About A&J International Patent Office

A&J International Patent Office is a Japanese patent firm jointly established in 2013 by patent attorneys Aida Shinji and Jung Wonkee.
Our principal work is representing clients before the Japan Patent Office — prior-art searches, filing and registration, trials, and litigation for patents, utility models, designs, and trademarks — to protect your intellectual property. In particular, we distinguish ourselves by focusing on the following:
- ·As the only Japanese patent firm managed by a Korean-Japanese patent attorney (as of March 2016), we ensure smooth communication with Korean clients.
- ·Jung Wonkee, our co-representative patent attorney, is a Korean-Japanese patent attorney fluent in both the legal systems and languages of Korea and Japan. All communication is available in Korean, and major correspondence can also be provided in Korean.
- ·We provide broad, international intellectual property legal services.
Beyond filing work before the Japan Patent Office and the field of IP protection, A&J International Patent Office leads in offering a wide range of legal services — including search work, customs injunctions related to patents, and plant variety registration applications — and leverages its global network to respond optimally to the international protection and utilization of intellectual property.
A&J Patent Office strives to be a reliable partner in intellectual property and a collaborator that helps bring success to your business.
Thank you.
