The United States Patent and Trademark Office (USPTO) is pleased to announce that, over the weekend, the Centers for Disease Control and Prevention (CDC) confirmed that all 88 samples taken at the USPTO tested negative for Anthrax. Consequently, the tests taken to date indicate that the USPTO is Anthrax free. In the interest of continued safety, the USPTO will test for Anthrax periodically. For the most current information on mail safety, please contact the official websites for the CDC and the U.S. Postal Service.
