“The Trademark Trial and Appeal Board (TTAB) of the U.S. Department of Commerce’s United States Patent and Trademark Office (USPTO) has expanded the options for electronically filing documents in trademark disputes. Using the Electronic System for Trademark Trials and Appeals (ESTTA) system, parties to a dispute now can file more documents electronically with the TTAB, including requests for extension of time to oppose and notices of opposition. Parties also can use ESTTA to file motions and other documents in inter-partes cases.” [Link]
