Question: What Are "89-" Trademark Registration Numbers?
In searching the trademark data base on the Web there are records that appear to be a registrations but the registration numbers are shown as 0000000. Is this an error?
Answer: No, this is not an error. The registration number 0000000 is associated with USPTO records that have serial numbers that begin with "89-". The prefix "89-" is assigned to material that the USPTO is obligated to protect either by law or treaty. However, since this material is not actually registered under the Trademark Act, it is not issued a registration number.
There are two types of material that are assigned "89-" serial numbers.
- One type is material that is used by U.S. federal agencies that should not be registered as trademarks unless the agencies themselves are filing the trademark applications.
- The second type is material that must be protected under various international treaties. The entities holding this material may be international organizations or foreign governments.
