Trade mark series applications

Around 40% of series applications don’t meet the requirements. We recommend you read this guide if you are considering making a series application.

If you have different variations of your trade mark then they might qualify as a series.

A series of trade marks consists of up to six marks in a single application.

For a series to be acceptable, the marks should:

  • look the same
  • sound the same
  • mean the same

Any differences must be minor.


A series of more than two marks is subject to an extra fee of £50 per mark.

This fee is non-refundable, even if we refuse your series application.
