Lacoste appealed this and was successful in the High Court, where Justice David Collins overturned the assistant commissioner of trademarks' decision.
Crocodile International then went to the Court of Appeal, which was satisfied Justice Collins' identification was correct, saying the crocodile image was the "central idea and message" of the logo, not the word crocodile or the combination of the word and logo.
"It is all about the crocodile," the appellate court said.
Crocodile International last year was given leave to take the case to the Supreme Court, which allowed its appeal in a decision this morning.
The country's highest court today revoked registration of the disputed trademark from December 1999.
"Lacoste has never used the trade mark anywhere in the world. There is no reason to retain it on the register [of trade marks]," the Supreme Court said.
Whether Crocodile International or any other company can now register a similar trademark was a different question, the judge said.
The judges awarded $25,000 in costs to Crocodile International.
