The company, which employs just four people, registered the Chelski trademark, which was adopted by the tabloid media after billionaire Russian owner Roman Abramovich bought the club in 2003.
After two-years of legal wrangling, the Patent's Office's Trademarks Registry has found in favour of Europa Wines' rights to keep the Chelski name, with Chelsea being ordered to pay 拢2,750 towards the small wine firm's legal costs.
Chelsea FC had previously registered its own trademark rights to Chelski, but the deal did not cover "possible brand extensions as products of interest".
The decision means that Europa Wines can continue to market the Chelski name across its range of drinks, and the company now plans to sell Chelski Blue, a blue vodka-based alcopop, across the UK.
Europa Wines, which is owned by Richard Gibson and Robert Gillard, have used the name to produce a range of products, including bed sheets, bath linen and, most lucratively, the Chelski Blue brand.
One-time Chelsea chairman Ken Bates had previously approached Europa Wines with proposals to sell its rights to the Chelski name or to enter into a joint venture with the club.
It is understood that Gibson and Gillard refused, prompting Chelsea to file a lawsuit against Europa Wines in March 2004 for "passing off" and making its application in "bad faith".
It is understood that Chelsea strongly oppose the Chelski Blue brand, citing that its choice of blue is very similar to the club's home kit.
But despite the club's considerable financial muscle, it could not stave off the challenge of Europa Wines.
According to Forbes, Abramovich is the second-richest person in the UK, just behind steel magnate Lakshmi Mittal, and the 11th richest person in the world. He acquired Chelsea FC for around 拢140m in July 2003.
