Mami Hino's practice emphasizes client counseling, strategic patent prosecution, post-grant opposition, invalidity trial and its IP High Court appeal, and infringement litigation. She collaborates with variety of clients from heavy machine companies to consumer product companies including chemical companies and pharmaceutical companies.

Due to her background as a registered pharmacist and experience working at the research laboratory of a pharmaceutical company, Mami Hino has extensive experience representing innovator pharmaceutical companies to protect their patents, such as filing patent term extension applications, defending their patents in invalidity trials and IP High Court appeals, filing preliminary injunction requests and/or patent infringement suits against generic companies.

Mami Hino studied law at a U.S. law school (J.D.) and practiced as an attorney at a New York law firm that specialized in intellectual property.
