Avoiding Fake Invoices
The U.S. Trademark Office routinely publishes allowed trademark applicationsfor potential opposition, prior to issuing the registrations. Similarly, some patent applications are published prior to patents issuing. These publications are available to the public and include the names and addresses of the applicants.
Patent and Trademark Offices do not send invoices for "issue fees" directly to companies (or individuals) already represented by attorneys. Instead, they send any notices or
invoices directly to your attorneys. If patent and trademark applicants receive these types of invoices and are unsure as to whether or not they are legitimate, they can simply forward them to their attorney.
