You've heard of fake news, but what about fake invoices?  Beware of bogus notices and invoices from imposters. 

Recently, there has been a proliferation of companies that pose as the U.S. Patent & Trademark Office (USPTO) which try to fool trademark owners into paying to them amounts needed to maintain or renew their trademarks.  These fraudsters mail trademark owners phony notices with names and typefaces so realistic that even sophisticated clients have been fooled.
