Patton returned to action and focused on the shorter sprint distance that year.
He finished eighth in the 100 m final at the 2007 US Championships and withdrew from the 200 m competition.
Based on his performance, he was selected to represent the United States at the 2007 Pan American Games.
He finished second in the 100 m behind Churandy Martina and anchored the relay team to a bronze medal.
He was chosen as part of the relay team for the 2007 World Championships and this time made the final after qualifying.
The American team (with Wallace Spearmon, Tyson Gay, and Leroy Dixon) became the world champions in a world-leading time of 37.78 seconds, fending off the Jamaican challengers who set a national record.

At the 2008 United States Olympic Trials, Patton achieved his lifetime best performance in the 100 m, running 9.89 seconds in the quarter-finals.
He went even quicker in the wind-assisted (+3.1 m/s) final, clocking 9.84 seconds, and came in third place behind Tyson Gay and Walter Dix.
He broke the 10-second barrier legally for the second time at the Herculis meet in Monaco, placing second behind Asafa Powell in 9.98 seconds.
During the 2008 Summer Olympics in Beijing he was the slowest qualifier for the 100 m final.
In the final itself he ran 10.03 seconds and was again the slowest and thus the eighth placed athlete.
Together with Rodney Martin, Travis Padgett and Tyson Gay he also competed at the 4 × 100 m relay, but they did not finish due to a mistake in the baton exchange between Patton and Gay and they were eliminated.

The following year Patton came second to Michael Rodgers in a close 100 m race at the 2009 US championships in June, running a windy 9.92 seconds.
This won him a place on the American team for the 2009 World Championships in Athletics.
Prior to the event, he was runner-up in Monaco and in Stockholm – running a wind-assisted 9.95 seconds behind Tyson Gay at the latter.
He managed to reach the final of the men's 100 meters after scoring a season's best of 9.98 in the semi-finals.
He performed poorly in the final however, finishing last with a slow time of 10.34 seconds due to an injury.
The hopes of the American men's relay team were again dashed by an illegal baton exchange, this time between Patton and Shawn Crawford.
Patton ended his season on a high: he ran a series of sub-10 runs including 9.95 for third at the Weltklasse, 9.94 to win the Hanžeković Memorial, and a personal record-equalling run of 9.89 seconds for third at the Shanghai Golden Grand Prix, behind Tyson Gay and Asafa Powell.
He also placed third in the 100 m at the Memorial Van Damme and the 2009 IAAF World Athletics Final.
