The online marketplace said the decision was an ‘important judgment because it ensures that consumers can continue to buy genuine products at competitive prices on eBay'.
eBay has also won legal victories in the US, France and Belgium.
Next month eBay in Europe will launch an online petition to try to amend EU competition law to remove barriers to trade.
While eBay claimed victory, L'Oreal said the court agreed that eBay could do more to stop trademark infringement. The High Court referred a number of items to the European Court of Justice for clarification and confirmation.
eBay said the European Commission is already addressing online trading issues with the drafting of new guidelines on the extent to which companies can restrict online trade.
L'Oreal argued that restricting the distribution of their products and preventing them from being sold on eBay protected consumers against counterfeit products. In court, of the 15 products hand-selected by L'Oreal as evidence against eBay UK, none was proven to be counterfeit.
