For UK trade mark applications, the basic costs are:
£200 for a paper application (Form TM3) for a single UK trade mark, registering your trade mark in one category of goods and/or services (class);
£170 for an online application (using Form e-TM3) for a single UK trade mark, registering your trade mark in one category of goods and/or services (class);
£200 for a paper application (Form TM3) for a series trade mark of two UK trade marks, registering your trade mark in one category of goods and/or services (class);
£170 for an online application (using Form e-TM3) for a series trade mark of two UK trade marks, registering your trade mark in one category of goods and/or services (class) only;
£50 to add an extra class (category of goods and/or services) for each class above the one class already included in the base fee for a paper or online application; and
£50 to add an additional mark (after the first two) in a series mark application (paper or online).
For example, if you apply online to register a trade mark in three classes, your fee will be £270 (£170 application fee + £50 additional class fee + £50 additional class fee). Similarly, if you apply via paper form to register a series of three trade marks, your fee will be £250 (£200 application fee + £50 additional series fee).
Note that there are usually additional costs if you need to amend your application during the registration procedure or if you apply for an extension of time. However, the UK IPO is waiving the fee for extensions of time from 30 July 2020 until 31 March 2021 due to the coronavirus pandemic. There are also costs involved in renewing your trade mark every 10 years.
