Online application form
Make sure you know what classes of goods or services you are applying for as you will need these to make your application.
If you
do not know which class(es)
your goods or services are in, please use the new Classification search tool EuroClass 
,
this will help you to search for and classify Goods and Services (terms) needed to apply for trademark
protection or, alternatively, contact us via our e-mail advice service.
We cannot refund your application fee for any reason and you cannot alter your trade mark after you have sent us your form.
We will capture the text style as it appears on your form TM3. We can't make changes to the text style after the mark has been filed and so if your mark is accepted, the same style will appear in the advertisement in our journal and on the registration certificate.
After starting a form, you must submit it within six hours or you will lose any data you have input unless you use the save for later option. This allows you to save the form and complete it up to 28 days later. Details of how to recover and continue your form will be e-mailed to you.
Official filing dates
If your application meets the necessary filing requirements, we will usually award the date of receipt of the application as the official filing date. However, this does not apply to applications which include a claim to priority from an earlier application which are received in the Office on a Saturday, Sunday or public holiday.
For these applications, the official filing date will be the next working day as the Office is considered to be closed on weekends and public holidays for the filing of these types of application.
Further details can be found on our hours of business pages.
