My brother recently started a new business called Solidlink Grating. He has been focused on getting all the products manufactured & ready for sale, whilst his competitors registered the 2 domain names he wanted
I suggested changing the trading name but all the casting for the manhole (covers) & gratings have been already fabricated with the solidlink grating name built into the casts.
After further investigation, I was told to take this to auDA the regulatory body to question the entitlement.
I hope this works, it would be devasting for a young bloke that's trying to get his business off the ground.
