Scam letters soliciting renewal of your federal trademark registrations are more prevalent and sophisticated. The most recent believable scam comes on letterhead marked “Patent and Trademark Office,” lists your registration number and mark, offers to renew the mark, provides a business reply envelope, and has a QR code that links to the actual US Patent and Trademark Office. Like other scammers about trademark registrations, it is not a legitimate company and may misstate the year in which you need to renew. Throw the document away. Do not send money. The real PTO does not send these solicitations. Your trademark registration might not be eligible for renewal for at least a year after the notice indicates. Stay vigilant.
