The logo of LONSDALE is typefied by a large L that underlines the entire trademark. The letters of the trademark also have a cinematographic lay out. This makes it a strong logo.
When LONSDALE found out clothes from LONDONER were using a similar logo, they were able to stop the import of these clothes from China, based on infringement of their logo. The LONDONER logo also used the same L and the letters had a cinematographic lay out.
