About us


The intellectual property (IP) environment has greatly changed within only a quarter of a century. IP practice as well as technology has become more complicated, and the importance of business and management strategies from an IP perspective is gaining recognition. Further, due to the severe competition, companies' IP needs are expected to continue to diversify.

Under such circumstances, FIELDS IP Attorneys was established as a patent firm which contribution to our clients' business is to provide high quality IP services which precisely meet our clients' needs.

We, at FIELDS IP Attorneys, are determined to always engage and really listen to our clients, as well as devote ourselves to working and learning in order to provide quality services beyond our clients' expectations and become the most reliable IP partner to our clients.
