What the Team is Known For

11 South Square offers great depth of expertise in IT and telecoms-related intellectual property matters, and is consistently recognised as one of the top IP chambers. Its tenants are sought out by major technology companies and corporate clients for some of their most substantial patent disputes, and barristers from the set have excellent knowledge of FRAND licensing matters. Recent highlights include the representation of LzLabs against IBM in the High Court. IBM accused LzLabs of intellectual property infringement and claimed that the company wanted to steal and copy trade secrets.

Ashley Carr is the senior clerk.
