In-use and non-use investigations

Whether considering trademark revocation, cancellation or opposition proceedings – or to make an assessment of a potential trademark infringement – Cerberus provides in use and non use trademark enquiries to allow for an informed decision.

We have a fixed–fee structure in place for all verification of use enquiry instructions; so you will always know the costs involved. We do not charge clients extra fees for urgent instructions with a short turnaround time.

We provide fixed-fees for trademark in-use enquiries in the following areas: 

  • UK
  • EU and Eastern Europe, USA, Australia and New Zealand
  • Asia/Pacific, including China and Hong Kong
  • Latin America & Caribbean
  • Middle East & Africa


An in use or non use  trademark enquiry by Cerberus will provide the following information:

  • Verification of the current status of a trademark or the date of last use
  • Information obtained from covert approaches directly to the target (unless inappropriate) and to third party sources
  • Establish the details of goods and services bearing the mark
  • Determine business activities of the trade mark owner
  • Extensive Internet and media searches to determine coverage of the mark and sales figures


Cerberus personnel can either speak or have easy access to a speaker of the following languages: Turkish, French, Spanish, German, Italian, Russian, Georgian, Bulgarian, Polish, Portuguese, Chinese (Mandarin and Cantonese) and Arabic. This allows us to offer international verification of use enquiries at a very competitive rate.
