Asahi, Sony and Panasonic also feature on the client roster. Frederick Ch’en is praised for his ‘great technical knowledge’ and ‘insightful guidance’, and Tomoe Takahashi is a recommended senior associate.

The practice assisted Toshiba with the IP aspects of its global carve-out and $500m sale of its home appliances business to Midea Group, a Chinese home appliances company. Max Olson ‘always provides very quick response times’ and successfully led the defence of Fujitsu Ten from a patent infringement allegation brought by Advanced Silicon Technologies before the US International Trade Commission.

Maxwell Fox, who joined the practice from Ropes & Gray LLP in 2016, is strong in contentious and non-contentious matters; he was part of the team that successfully represented NEC and its US subsidiary, NEC Corporation of America, in multi-jurisdictional patent infringement litigation filed in the Eastern District of Texas by Uniloc. Mitsubishi Cable Industries, Canon and Dell are other notable clients.

The practice at Orrick, Herrington & Sutcliffe LLP is led by David Case, who has handled a number of IP and IT contentious and transactional matters for Japanese and multinational clients, such as Yamaha and Ricoh.

The defence of JVC Kenwood and JVC Kenwood USA in patent litigation filed by Hybrid Audio in the District Court of Massachusetts is another work highlight. Yoshihiro Takatori and Kei Kato are other names to note.

Paul Hastings LLP’ IP practice, which was established in 2016 after practice head Hiroyuki Hagiwara left Ropes & Gray LLP, handles IP litigation and licensing, particularly in the fields of pharmaceuticals, technology and telecoms, and works in close collaboration with colleagues in the US. The team successfully defended Olympus in a patent infringement action in the Eastern District of Texas and advised Japanese internet media company Gree on licensing game application patents to competitors. Fujitsu and Mitsubishi Tanabe Pharma are other clients.
