Club accepts compromise after cease-and-desist dispute

Chelsea Football Club has backed away from a sweeping demand that a small west London software company abandon its name, change its branding and surrender its website domain.

The dispute began when Ben Auffarth, a computer scientist who founded Chelsea AI Ventures in early 2025, received an email from intellectual-property specialist Abion acting for Chelsea Football Club Limited. The club argued that the company’s use of “Chelsea” was too similar to its trademarks and could lead customers to believe the software business was connected to the football club.

The letter cited Chelsea’s extensive trademark portfolio, which covers “Chelsea” and “Chelsea FC” across numerous categories, including software. It said the addition of “AI Ventures” did not sufficiently distinguish the company because those words described the services it provided.

Abion demanded that Auffarth stop using the name, avoid registering similar trademarks and domain names, change the company’s blue-and-white colour scheme, apply to change its registered company name and transfer the chelseaai.co.uk domain to the club without charge. Failure to comply, the letter warned, could lead to claims for damages, an injunction, legal costs and other remedies.

“Chelsea is a place as well as a football club”

Auffarth said his business had never presented itself as affiliated with the club. He argued that Chelsea is also a geographic name used by local organisations, pointing to the Chelsea Flower Show and the Royal Hospital Chelsea as examples.

He also raised comparisons with other trademark disputes, including Iceland Foods’ unsuccessful attempt to retain broad rights over “Iceland”, Liverpool FC’s failed effort to trademark the name of the city of Liverpool, and the rejection of “Las Vegas Athletics” as too generic and geographically descriptive.

“At what point does protecting a football club’s brand become an attempt to control the use of the place name itself?” Auffarth asked.

Experts divided on the club’s legal position

Colin Bell, head of intellectual property and technology at Brabners, said Chelsea could argue that the word had acquired distinctiveness through the club’s global reputation. He also noted that trademark owners have a legitimate reason to enforce their rights so that marks are not diluted.

However, Bell said the club might struggle to show that the software company’s services were identical or sufficiently similar to the goods and services covered by its registrations. A claim that the company was taking unfair advantage of Chelsea’s reputation would also require the club to prove economic harm and show that the use lacked “due cause”.

Jasmine Fearnley, a senior associate at Mills & Reeve, was more critical. She described the dispute as “a classic example of a brand owner trying to monopolise the use of the name of the geographical area they operate in”.

“Chelsea is a geographical name, and its use can’t be monopolised across all products, services and sectors,” Fearnley said. She added that the club’s rights were likely to be stronger in football, sporting services and merchandise than in software.

Fearnley also warned that an aggressive legal demand can create a damaging David-versus-Goliath narrative for a major brand. In this case, she said, a request to change the colour scheme might have addressed any concern without forcing a complete rebrand.

Agreement ends the dispute

Auffarth’s lawyer ultimately offered a compromise: Chelsea AI Ventures would change its colour scheme and would not use “Chelsea” on its own in company documents, marketing or products. Abion accepted the proposal.

“It’s a huge relief,” Auffarth said, explaining that losing the email address and domain name could have cost the company leads and business opportunities. He said the original letter felt aggressive and had potentially threatened his livelihood.

The football club declined to comment, but the settlement avoided a court battle and allowed the software company to retain its core identity while addressing the club’s branding concerns.
