I don't think it will be the Chinese they have to worry about. Objections can and probably will be made to their patent applications by their competitors here in Australia.
Lifestyle could potentially be turning the camper trailer market into a litigious nightmare.
This is simply a shot across the bow to deter those who may wish to copy it. Applying for a patent and having it registered are two vastly different things.
I have been through the process somewhat, and unless you have a bonafide original idea AND lots of money to engage a international patent, lawyers etc, you will never stop someone from copying your product. And then if they do, you have to take action against them in their own country - that's if their govt gives a toss. Imagine not being able to speak the language, don't know the customs, not even a citizen - trying to sue some Chinese bloke!
Best to get your product out there quickly, with lots of publicity, and let everyone know you have the original and genuine product.
