Maki Saitoh is a patent agent in the firm’s Chemical Patent Prosecution practice group, where she writes and revises patent applications for a variety of domestic and international clients in a wide range of technical areas.

Prior to joining the firm, Ms. Saitoh worked as a patent analyst at a patent search company conducting prior art, invalidity, and freedom-to-operate/infringement analyses. She also performed long-term patent landscape studies to identify trends in a technology field, deliver competitive intelligence and identify potential research and licensing opportunities.
