An anonymous reader sends word that many online systems at the United States Patent and Trademark Office are down due to damaged equipment after a power outage. A statement from the USPTO reads in part: "A major power outage at USPTO headquarters occurred last night resulting in damaged equipment that required the subsequent shutdown of many of our online and IT systems. This includes our filing, searching, and payment systems, as well as the systems our examiners across the country use. We are working diligently to assess the operational impact on all our systems and to determine how soon they can be safely brought back into service in the coming days. We understand how critical these systems are for our customers, and our teams will continue to work around the clock to restore them as quickly as possible, though the impacts may be felt through the Christmas holiday. We know many people have questions regarding filing and payment deadlines. We are reviewing this topic and will provide an update when we have further information."
