The IPKat hopes that everyone at WIPO is well and that the Office will be able to encourage creativity and innovation again on Monday. In the meantime, Richard Gallafent might be pleased to read that the German Patent and Trademark Office (DPMA) has a similar "warning against misleading requests for payment" on its website (English).
UPDATE: as just pointed out by the IPKat's observant friend Keith Gymer (Page Hargrave) OHIM also provides a scam list with images on its website "....but CRPT isn't there yet...!"
