He studied Civil Engineering at Georgetown College, graduating in 1838, and returned to the Navy, assigned to work with the U.S. Coast Survey.
He graduated from Georgetown College in Kentucky as a civil engineer in 1838, and was attached to the United States Coast Survey from 1838 to 1841.

[7] When California was made a state by Act of Congress, it was Patterson who brought the news to San Francisco, arriving on October 18, 1850, resulting in city-wide celebrations lasting well into the night.
During the Civil War, the role of the Coast Survey included preparing charts and other material to help United States Navy ships execute the Union blockade of Confederate ports (the strategy known as the "Anaconda Plan").
As a result of these pre-war and wartime connections, the Pattersons were well-known to Grant and other leading Union officers.
Patterson was one of the early members of Washington's Metropolitan Club, which included numerous Union generals, admirals, and other officers.
A large oil portrait of Patterson's brother-in-law, David Dixon Porter, hangs in the first-floor lobby (as of 2007).
Another sister, George Ann, and her husband David Dixon Porter were interred at Arlington National Cemetery.
