It is official now. "Shier" is a registered U.S. trademark. I received this certificate in the mail along with a notice about scam artists who mine the USPTO registration database and send fake invoices to anyone who registers a trademark. The scammer letters say "you owe us x amount for registering your mark internationally." The x amount is typically $2500, which they ask you to wire directly to a Czech or Russian bank. There were 5 scam letters arriving at the same time as the certificate.
