Since TMI was founded in 1990, the firm has worked to create a law firm that is distinct from any other in Japan and to recast the image of both lawyers and patent/trademark attorneys. During the past 28 years, the firm has experienced rapid organic growth, both numerically and geographically, while maintaining its progressive culture. Starting in 1990 with 43 personnel, including 10 lawyers and two patent attorneys, TMI now has 425 lawyers (admitted in Japan and/or other jurisdictions) and 79 patent/trademark attorneys among a total of 864 personnel as of 1 August 2018, and it has become one of the five largest law firms in Japan. TMI provides a wide range of global legal services through its Chinese Practice Group, French Practice Group and Indian Practice Group located in its Tokyo office and its joint venture relationships in Japan with Morgan, Lewis & Bockius (US) and Arqis Foreign Law Office (Germany). The firm has branch offices overseas, in Shanghai, Beijing, Yangon, Singapore, Ho Chi Minh City, Hanoi, Phnom Penh, Silicon Valley and London.
TMI provides a comprehensive range of legal services regarding international corporate transactions and international investment and trade business transactions. The firm continuously seeks to expand its support for the global business development and needs of its clients – both Japanese and international innovative companies – with services ranging from the acquisition of patent rights to licensing, mergers and acquisitions, financing matters, down to dispute resolution.
