Abstract
This article surveys the history and development of the public
domain in intellectual property law. The public domain has existed
since time immemorial, and was first recognized in the Statute of
Monopolies and the Statute of Anne, which placed time limits on
patents and copyrights, after which the invention or work could be
copied freely by anyone. The concept was enshrined in the U.S.
Constitution and reflected in American patent and copyright laws.
Before 1896, courts referred to matter not protected by patent or
copyright law as public property or common property.  In 1896,
the U.S. Supreme Court imported the term 'public domain from
French law, and it was popularized by Learned Hand in the first
decades of the 20th Century. Since 1960, the U.S. Supreme Court has
repeatedly emphasized the Constitutional dimensions of the public
domain. Those dimensions include two important principles that have
been obscured in recent years: public ownership of matter in the
public domain and the irrevocable nature of the public domain.
I. INTRODUCTION
The public domain is something that we enjoy every day without
thinking about it. We take it for granted that the plays of Shakespeare and
the symphonies of Beethoven are in the public domain and may be freely
copied, adapted, and performed by anyone. Our theaters are filled with
movies and musicals based on public domain works. We daily use
technology derived from earlier inventions, such as the car, the airplane, the
telephone, and the computer. We understand intuitively that any scientist
may rely on Newton's laws of motion or Einstein's theory of relativity as he
or she sees fit. We use common words that once were brand names such
as, aspirin, cellophane, thermos, and escalator. Students and scholars debate
historical events, ranging from the origins of man to the impeachment of
President Clinton.
