What is the filing fee required for a request to update ownership information?

The filing fee for a request to update ownership information in a trademark registration with the U.S. Patent and Trademark Office is indeed $100. This fee reflects the administrative costs associated with processing the change of ownership and is applied to maintain the integrity and accuracy of the trademark registry. When a trademark is assigned or when ownership starts to involve a new party, filing this request ensures that the register accurately reflects the current owner, which is important for maintaining the rights and obligations associated with the trademark.

It's crucial to properly update ownership to avoid any potential disputes over rights and to facilitate any future dealings with the trademark, such as licensing agreements or additional filings. Other choices reflect incorrect amounts, which do not align with the current established fee structure of the USPTO for such updates.
