“My experience with Keisen has been nothing short of excellent. I have found your firm to be very responsive and very helpful when dealing with issues surrounding Japanese patent applications. I also find that it is incredibly beneficial to have a Japanese associate in Philadelphia…this simplifies my work because we are in the same time zone for urgent communications. It is also useful when I would like to have an in-person discussion, as you are just a short drive away.”
