Valuable Patents Unearthed

Recently, some rare copies of early American patents were discovered in a library at Dartmouth College.

A fire at the U.S. Patent Office in Washington in 1836 destoyed most of the country's 10,000 or so early plans.

Host Lisa Peakes speaks with Attorney Scott Asmus who was doing research on New Hampshire inventor Samuel Morey when he and a colleague found copies of 14 early patents.

Copies of many existing historic patents can be viewed at the U.S. Patent Office website at http://www.uspto.gov/
