 From 1999 to 2008, a change in the statute governing the United States Patent and Trademark Office ("USPTO") permitted a number of judges of the Board of Patent Appeals and Interferences and the Trademark Trial and Appeal Board to be appointed by the USPTO Director.This arrangement was challenged as unconstitutional under the Appointments Clause because the appointing party was not the Heads of the Department.In order to avoid the crisis that would result from new challenges to many BPAI and TTAB decisions made in that period, Congress passed a 2008 amendment to the statute which specifies that the Secretary of Commerce is responsible for such appointments, and permitting the Secretary to retroactively appoint those persons named by the USPTO Director.
