For anyone interested. This is a website about Australian IP and trademarks. It looks like Rickenbacker forgot to renew the trademark back in 2007, and as a result the trademarks have been removed from the register. So these kits, which only have a resemblance to Rickenbacker, are legal anyway because Rickenbacker's IP has not been protected in Australia for the past 7 years.
Furthermore, as this company is producing a kit which is not an exact copy of a Rickenbacker trademark, a local trademark could then be registered in Australia for this design, guaranteeing the legality of this production.
