WARNING: IP-Data.biz appears to be operating a scam, preying on ignorant trademark registrants. The modus operandi appears to be the active monitoring of the trademark registrations, whereby they send fraudulent invoices to the trademark registrant, asking for $2000 or more, in what appears to be an official looking invoice somehow related to the trademark registration process. However, these invoices are unsolicited, they are noted with order numbers, invoice numbers, bank wire transfer information etc. It appears that this is a fire-and-forget invoicing scheme, issued in the hope that ignorant accountants will pay the invoice without first checking it out with their intellectual property lawyers.
