HISTORIC PATENTS  
Although there is some evidence suggesting that something like patents were used among some ancient Greek cities, most historians agree that patents in the modern sense originated in Italy in 1474. The Republic of Venice issued a decree by which new and inventive devices had to be communicated to the Republic in order to obtain legal protection.

In the United States, during the colonial period and Articles of Confederation years (1778-1789), several states adopted patent systems of their own. The first Congress adopted a Patent Act, in 1790. Since its founding in 1790 the United States Patent and Trademark Office (USPTO) has issued over 7 million patents, of that number approximately 70 thousand have become legitimate products. Although most patents are obscure and long forgotten, in the 1% that did become successful are some very significant inventions that have changed the way we live our lives. We have grouped these historic patents into three distinct time periods to ease your review of these inventions.

Historic Patents 1790 -1836
