Aki Ryuka is president of Ryuka. He is a Japanese Patent Attorney, is certified to practice IP litigation in Japan and is qualified as an attorney-at-law in California, United States. He handles prosecution, licensing, litigation, opinions, and Customs surveillance in the fields of Japanese patent, design, and trade mark law, specialising in electronics, semiconductors, software, data communication and radio communication.

In 1987, Ryuka began his career as an electrical engineer in the facsimile machines department of Canon. Five years later, he joined Tani & Abe Patent Attorneys in Tokyo, Japan, where he prosecuted patent applications for foreign and domestic applicants including Canon.

From 1995 to 1998, Ryuka worked in the Washington, DC office of the US firm Cushman Darby & Cushman (now Pillsbury Winthrop Shaw Pittman LLP), where he mainly prosecuted patent applications for Japanese clients. At the same time, he established a patent firm in Japan and a translation company in the US, the predecessors to Ryuka IP Law Firm, facilitating business for Cushman Darby & Cushman. While in the US he passed the US patent bar exam.

Since founding Ryuka IP Law Firm, he has lectured extensively in Japan and abroad on IP topics, has published numerous articles including recently detailing Ryuka's invention consulting services (patent visualisation), and visits clients and attends conferences in the US, Europe, and Asia. Recent work in 2012 includes representing a large US client in nullity trials before the Japan IP High Court and Supreme Court, in cooperation with Nagashima Ohno & Tsunematsu, and representing a large Korean client in infringement and nullity trials in cooperation with Anderson Mori & Tomotsune.
