In 1790, Paterson was one of the investors in the Boston Patent, a large land grant in Broome and Tioga Counties, New York.
 In 1791, he moved to Lisle, a newly-organized town in Tioga County.
 He was a member of the New York State Assembly in 1793.
 The area of Lisle where Paterson settled was later organized as the town of Triangle; the site of his home and farm was in what is now the village of Whitney Point.

In 1798, Paterson was appointed judge of the Tioga County Court, and he served until 1806.
 When Broome County was organized separately from Tioga in 1806, Paterson was appointed judge of the new county's court.

In the late 1700s and early 1800s, Deborah Sampson published a memoir and made a lecture tour in which she gave presentations about her military service.
 Her tour took her to New York, and from November to December 1802, she visited Paterson in Lisle.
 While she stayed with Paterson, Sampson was able to take part in reunions with other former Massachusetts soldiers who had settled in the area of the Boston Patent.

In 1802, Paterson was a successful Democratic-Republican candidate for the United States House of Representatives.
 He served in the 8th United States Congress (March 4, 1803 – March 3, 1805), and was not a candidate for reelection in 1804.
