PATENT SECURITY CATEGORY REVIEW LIST

This is the first edition of an ASPAB composite category review list of the categories of inventions that should
be made available in accordance with 35 USC 181. It resulted from a review and revision of the composite list
previously used by the Patent Office. The list was compiled by the ASPAB Sub-Committee for Revision of the
Category List comprised of representatives from the Army (AMC), the Air Force, and the Navy with the co-
operation of CE, AEC, NASA, and NSA. The assistance of Mr. Charles Pistorino, CE; Mr. Anthony
Campana, AEC, Mr. Howard Maines, NASA; and Mr. John Utermohle, NSA was of significant value in this
