EMS Copyright, 1984
In 1984, the U.S. Copyright Office issued TXu-169-126, the first Copyright for EMS (EMAIL Management System), to (V.A.) Shiva Ayyadurai. The EMAIL copyright had been awarded to Shiva two years earlier. This copyright recognized his additional contribution for creating all the internal tools needed by system administrators to maintain EMAIL and messages long-term, e.g. archiving, password management, etc.
Even in 1984, the only protection available for software was through Copyright. The U.S. intellectual property laws, at that time, treated software similar to music, art or literary work. The original Copyright application was submitted in 1980, following completion of the EMAIL software, two years after Shiva began its development starting in 1978.
