The issue of patents for new discoveries has given a spring to invention beyond my conception.

THOMAS JEFFERSON

The Patent System added the fuel of interest to the fire of genius.

ABRAHAM LINCOLN

The American Patent System has promoted countless applications of the arts and sciences to the needs and well-being of our people.

FRANKLIN D. ROOSEVELT

Soundly based on the principle of protecting and rewarding inventors, this system has for years encouraged the imaginative to dream and to experiment-in garages and sheds, in great universities and corporate laboratories. From such explorations on the frontiers of knowledge has welled a flood of innovations and discoveries which have created new industries and reactivated old, giving more and more Americans better jobs and adding greatly to the prosperity and well-being of all.

DWIGHT D. EISENHOWER
