We recently filed a trademark application for our company, PageFair. This morning I received (by snail mail) this official-looking invoice from the "European Patent and Trademark Register" for extra filing fees. It turns out it’s a complete scam. A Polish company appears to be monitoring for new trademark applications and attempting to phish a thousand Euro from each applicant.
[UPDATE: See below for a second similar scam letter we received]
The small print says it all:
“Please notice, that this form is not an invoice. This is an offer for the annual registration of your Trademark in our Internet database.”
Better luck next time, losers.
