At last.... a case of a win for the little guy.
After some big American 'Johnny-Come-Lately' decided to hijack the name...by registering it....it all looked like the 'bastards had won again'....but no, what has been a generic term for sheep-skin boots, in Australia for around a half century has been determined in court as Generic....and SO IT SHOULD.
The biggest insult was the demand-letter to the Australian Macquarie Dictionary to alter its definitions to include 'Dekker' as trademark owner, etc.
You can sell the bloody shoes...but you cannot own the idea.
Stick that in your corporate pipe....and smoke it....
