Practice head(s):

Isabella Liu


We have been using Baker McKenzie for at least more than two decades for trade mark matters. We appreciate them for their great deal of experience in trade mark issues; and they have a deep understanding of the law but at the same time can provide practical and constructive options in a timely manner.

They understand the business goals of their client, as well as the character and likely options available to adversaries. This facilitates communication and alignment on strategy.

The team is very intuitive and responsive to our needs.

They are not scared to think outside of the box and we ascribe our success in combatting the infringement of one of our varieties in China to the unorthodox thinking and problem-solving techniques of the team.

BM is expensive to deal with, but it provides peace of mind knowing all the i’s are dotted and t’s are crossed.

Andrew Sim is always available, has unorthodox thinking, which might be scary to some, but it is this out-of-the-box style of working that has made us so successful in China.
