A Wimbledon businessman is celebrating slaying fast food giant McDonalds in a courtroom battle over the name of his Chinese restaurant chain McChina.

The High Court judge presiding over the case rebuked the inventors of the Big Mac for seeking to monopolise all names and words with the prefix Mc or Mac.

The fast food chain objected to McChina owner Frank Yu Kwan Yuen, registering the name as a trademark in 1992 and his application was refused.

But last week, Mr Justice Neuberger said Mr Yuen, who founded the first of his four-restaurant chain in Haydons Road in 1991, would be allowed to continue trading under the name.

A relaxed Mr Yuen told the Guardian he was relieved his six-year fight had been successfully won.

This is an important decision. Its very good news.

The judge agreed with Mr Yuens appeal that McChina would not confuse potential customers who would almost all be looking for oriental food.

Although McDonalds sells food bearing oriental-style names, such as Chicken McNugget Shanghai, Oriental McRib and McFortune Cookie, the judge said the range of food did not come on to the market until after 1992.

Mr Yuen will now be able to proceed with his plans for a national food chain offering Chinese cuisine.

A McDonalds spokesman told the Guardian: We are currently examining the issued judgment.

However, it is not possible to discuss any individual cases.
