The Supreme Court of the United States will begin electronic filing next month!  The announcement from the clerk of court states:

“On November 13, 2017, the U.S. Supreme Court’s electronic filing system will begin operation. While paper will remain the official form of filing as under existing practice, parties represented by counsel will also be required to submit most documents through the new electronic filing system. Attorneys who expect to file documents electronically will need to register in advance for the system.
