What does it mean to transfer or assign ownership of a trademark?

An ownership transfer or assignment occurs when the trademark's ownership changes hands due to a transfer of rights, sale, gift, merger, or similar reasons.

All transfers or assignments must be reported to the Trademarks Office to ensure the trademark is registered under the correct owner.

The ownership transfer or assignment must be submitted to the Trademarks Office (which may or may not charge a fee depending on the country) along with the necessary documentation that verifies the transfer of rights, sale, gift, merger, etc.
