Areas of trademark expertise

The group has extensive experience in standard trademark matters, including searching, clearance, filing, prosecution, opposition, invalidation, revocation, advising on infringement, appeals to the relevant tribunal or court and domain name disputes. The group also has particular expertise in the following areas:

  • registration of unusual or otherwise difficult marks, including shape marks and marks that require evidence of acquired distinctiveness;
  • clearance of trademarks and inventive, commercial thinking about dealing with earlier rights;
  • dispute resolution – the group has mediated the settlement of many disputes, sometimes in circumstances where previously involved firms have reached an impasse. The group brings to bear a thorough grasp of the legal issues, shrewd assessment of the strengths (and weaknesses) of the parties’ cases and an appreciation of any sensitivities that may need to be taken into account to reach a sensible conclusion; and
  • opposition and related enforcement issues – J A Kemp’s attorneys do not waste time and fees by adopting a ‘kitchen sink’ approach to trademark oppositions. They think carefully about the possible grounds of opposition and identify the strongest. They have an eye on the marketplace. They focus on actual use and not just the state of the Trademarks Register.

J A Kemp’s attorneys are passionate about their clients’ brands. They like to engage with their clients, embrace their business aims and discuss their future projects. They plan ahead, thinking about what searches to conduct and when and where to conduct them, what marks to protect with trademark applications and when and where to file those applications for maximum commercial benefit.
