Explanation:

In the late 18th and early 19th - centuries, the U.S. patent system had low fees which made it accessible to more inventors, and public displays which showcased inventions and inspired participation. Restricted access would discourage participation, private patents and international - companies were not key early incentives, and high fees would be a barrier.

Low fees and public displays
