What Inspired Me to Become a Patent and Trademark Attorney

I was engaged in a patent-related work in a company, where employees were judged by educational background and seniority, and sociable persons tended to be promoted rather than persons with ability. Seeing many employees promoted based on factors other than ability, I felt that this was not where I should be, and that even if I was luckily promoted here, I would not be rich enough to own a Mercedes.
A work as a patent and trademark attorney requires knowledge of both technology and law, and to use wisdom and compete using one's brain. The work, I consider, is nothing to do with educational background, but is based on one's own ability like sports, and gives me challenging career and worthy outcome. So, with only one life to live, I decided to pursue career as a patent and trademark attorney, which is judged on one's own merit.

Challenging and Interesting Work

I am very passionate about being a patent and trademark attorney, especially when useful patent right is obtained and my client is able to earn great profits from patent royalties because of descriptions in Claims that I came up with after many hours of studying related documents, over and over, day and night.
Also, I feel fulfilled when I see that a small company comes to own their head office building soon after obtaining a patent right, or when I receive a reward for success and moreover a word "Thank you" from my client to whom I contributed in solving their troubles successfully.
I experienced being thanked by an individual inventor who I had supported apart from a profit-and-loss calculation, or being given credit for having argued the other party down in court procedure by only one written statement I prepared for my client. In this way, I proceed with my work, realizing it is challenging and interesting.
