On December 19, the U.S. Copyright Office published an interim rule in the Federal Register amending its regulations governing the appearance of law student representatives before the Copyright Claims Board (CCB), district court referrals, proof of service forms, and default proceedings. The interim rules allow the CCB to modify or suspend certain rules when a claim is referred by a district court and, in cases that are first filed before the CCB, accept alternative proof of service forms. The new rules also clarify the rules governing default proceedings and law student representations. Comments are due by February 2, 2023.
