US Patent and Trademark Office notifies filers of years-long data leak

The federal government agency responsible for granting patents and trademarks has confirmed it inadvertently exposed about 61,000 filers’ private addresses in a years-long data spill.
The U.S. Patent and Trademark Office (USPTO) said in a notice sent to affected trademark applicants that their private domicile address — often their home address — inadvertently appeared in public records between February 2020 and March 2023.
U.S. law requires applicants to include their private address when submitting a trademark application in efforts to crack down on fraudulent trademark filings.
