Can you trademark a foreign word?
Yes, you can trademark a foreign word. You may use a foreign word or phrase to brand your goods or services, and therefore can trademark it.
For example, the French phrase “C’EST LA VIE” is a registered trademark for a line of cigar products. If you select a distinct foreign word or phrase, you may trademark it the same way that you would any other name, slogan or logo.
When you successfully trademark a foreign word or phrase, it will prevent any competitors from using that particular word or phrase to promote or sell similar products or services. It will not prevent people from using the word or phrase conversationally. The Trademark Office may decline your application if the foreign word serves as a generic term for your goods or services.
