The UK Intellectual Property Office (UKIPO) is set to abolish series marks as part of its digital transformation programme. This change is expected to take place in Autumn 2025 and will have significant implications for brand owners, IP managers and counsel who currently rely on the cost-effective and flexible benefits of series filings.
What are series marks?
A series mark application allows an application to register up to six marks in a single filing, provided the differences between them are non-distinctive and minor e.g. variations in punctuation, colour, spelling or font.
For example, a series might include:
The above would all be filed under one application and one fee in the UK.
Why is the System Being Abolished?
Following a public consultation in 2023, the UKIPO decided to scrap series marks entirely. Key reasons included:
- Low usage – fewer than 1% of trade mark filings make use of series applications.
- Inconsistency – there was significant variation in how examiners interpreted the rules.
- Confusing – applicants often misunderstood the limitations.
- International mismatch – most IP offices worldwide do not recognise series marks, creating extra complexity for global brand strategies.
In light of this, the UKIPO has opted to retire the system in favour of a more streamlined and internationally aligned approach.
Applicants will no longer be able to file a single application for similar marks. Each variation will require a separate application, including separate fees and individual examination.
What's Changing – and What's Staying?
- Each version of a trade mark will need to be filed separately, with its own application, fee and examination process.
- Existing series marks will remain valid and enforceable – the change applies only to new filings made from Autumn 2025 onwards.
What Now?
If you have previously relied on the series mark system to protect your brand, you should take early action:
- If you're planning to launch or renew a brand, consider filing series applications as soon as possible to take advantage of the current rules.
- Review your existing portfolio: Are your series marks still providing the right coverage? Are additional applications needed to support enforcement or future growth?
- Prepare for increased filing costs: Post-abolition, brand variants will each require a separate application – budget accordingly.
- Think globally: This move aligns the UK more closely with EU and international practice. Now is a good time to ensure your global IP strategy is consistent.
