timely warning from IPAustralia.
This kind of thing has been going on for a while, but seems to have developed more momentum lately.
Please remember to contact your patent attorney if you receive an offer of IP services before spending any money. Such an offer will invariably be a scam of some sort.
The above link is very useful because it sets out a list of companies known to send offers of IP services. But just because the company is not listed, don't think it's not some sort of scam.
