Leadership means I need to work hard as a role model to set a good example to others at the firm. It also implies a full range of abilities, from client care and marketing to management, as well as a broad expertise in the IP field. Since IP legislation and practice keep changing in China and the rest of the world, it also means a strong ability to learn and improve so as not to be left behind. In essence, it means a lot of effort and hard work.
