Established in 2017, ZeLo has quickly emerged as a dynamic corporate law firm in Japan, with particular strength in mergers and acquisitions, dispute resolution and finance. The firm has developed significant expertise in emerging sectors including artificial intelligence, Web3, healthcare and mobility, while maintaining traditional corporate advisory capabilities. Its intellectual property practice, launched in 2020 and led by practice head Toshihiko Adachi, handles patent and trademark filings while supporting the firm's broader corporate work.
Work highlights
Advised GungHo Online Entertainment as exclusive patent attorney adviser on comprehensive intellectual property management and enforcement. The firm implemented a centralised IP rights management system to address staffing challenges and conducted copyright investigations for brand protection. The ongoing mandate has strengthened GungHo's IP operations and rights management efficiency despite internal talent outflow.
Advised Toyoshima & Co, a leading textile trading company, as patent attorney adviser on strategic intellectual property protection and innovation support. The firm manages multi-country patent filings and Patent Cooperation Treaty applications while developing risk-mitigated trademark strategies. The annual engagement has helped strengthen Toyoshima's global competitiveness and enabled its subcontractors to access government subsidies, potentially setting a precedent for patent rights in the fashion sector.
