They defeated second seeds and all-American pair of Scott Lipsky and Rajeev Ram 6-2, 6-7 (7-1), 10-7 in the semi-final. Paes and Tipsarevic were staring at defeat, down 0-5 in the final tie-breaker, but clawed their way back into the game to win 10-7.
Earlier, in the other semifinal, fourth-seeded pair of Andy Ram and Jonathan Erlich sent the top-seeded Indian duo of Mahesh Bhupathi and Rohan Bopanna crashing out of the tournament with a 4-6 6-3 10-8 upset win.
Paes said he wished it had been easier, but added, "One thing we share is the work ethic. To come back from 0-5 down just shows a lot of heart. I love it how Janko puts it on the line every time he's on court."
Tipsarevic, who was playing his second match of the day after winning his singles semifinal against Go Soeda of Japan, said, "I haven't had this much fun in a long time. I played a tough match. I am really happy."
After the ouster of Bhupathi and Bopanna, it looked as if the doubles final would be void of Indians with Paes and Tipsarevic staring defeat in the face in the decider.
However, the Indo-Serbian pair bounced back thanks to some superlative netplay by Paes and strong returns from Tipsarevic to which their opponents had no answer.
They wrapped up the match when, with Paes and Tipsarevic on 9-7, Ram and Lipsky let a Tipsarevic screamer from the baseline go past between them.
