Isshiki & Co. has changed its firm name to Isshiki Patent and Trademark Firm as of January 1, 2023 due to the amendment to the Patent Attorney Act. In addition, Kensuke Isshiki who founded Isshiki & Co. in 1976 has resigned as the President and became the chairman of the firm, and Kazuo Isshiki became the firm’s sole President.
