Registering a UK series trademark, several close variants under one number, is a legally sound way to cover minor differences in a logo or name.
Fox tried a last-ditch argument that the Glee Club's trademark registration was invalid because it was registered as a "series" of two similar marks. The Court of Appeal disagreed, so the earlier finding that Fox's Glee show infringed the mark stood.
What happened
Comic Enterprises, which runs Glee Club comedy venues, had already won a finding that Fox's TV show Glee infringed its trademark and diluted its reputation. Fox appealed, lost, and then tried a new argument: that Comic Enterprises' trademark registration was invalid. The registration consisted of two very similar device marks registered together as a "series" under UK law. Fox argued this UK mechanism clashed with EU rules that a trademark must be one clearly defined sign. The UK Intellectual Property Office was asked for its view before the Court of Appeal ruled on the point.
What did the court decide in Comic Enterprises v Twentieth Century Fox Film?
The Court of Appeal held that a UK series registration isn't one combined trademark. It's a bundle of separate marks, each registered under a shared reference number, and each one still has to meet the normal rules on its own, including being capable of clear graphical representation. Looking at the relevant EU case law on what counts as a valid trademark, the court found no clash between the UK series system and EU law. It declined to send the question to the Court of Justice of the EU and rejected Fox's challenge, so the earlier infringement finding against Fox stood.
What we learned from this
- What I'd take from this is that business owners who register a name or logo as a UK series trademark don't need to worry that the format itself is a weak point to be attacked later.
- Each mark within a series still needs to meet the usual registrability tests on its own, so it's worth checking that every variant in a series registration stands up independently.
- A series registration can be a practical way to cover slightly different versions of a logo or name without filing separate applications for each one.
Things to be aware of
- Series registration is a UK-specific tool with no direct equivalent under EU trademark law, so this reasoning may not carry over to EU-wide trademark filings.
- The ruling confirms the format is valid, but it doesn't change the separate question of whether any individual mark in a series actually qualifies for protection.
- This case followed years of litigation, including an earlier High Court trial on infringement, so the series mark point was only reached after the main dispute was settled on appeal.
