In brief - Beware of false billing scams and consider an
internal process to manage this risk
You are more than likely to receive scamming notices and bogus
invoices in relation to your registered trade marks.
Unscrupulous operators can find you easily because trade mark
registration details are available on the web.
Often what you will receive looks like the real deal. So it is
easy to be conned and you end up paying 10 or 20 times more what is
a fair charge for a process in connection with your trade mark, or
paying for something that isn't even needed.
IP Australia, the government agency for trade marks, regularly
issues warnings of its own. However, there is not much that can be
done to stop those operators.
